Email: suvarnanarayanan2g (at) gmail.com
I have quite some experience dealing with LLM based applications - taming them into giving more sane answers. The best one that I have built so far lets you attach to any data sources (SQL/NoSQL/Files) etc and then just ask questions about them. Literally any question (even outside the schema) and it never makes up stuff.
My going rate at the moment is $5 per hour (subject to complexity and my preference) - capped at 8 hours a day for 5 days a week, which is around $200/wk at minimum.
I am very transparent about my work and I do not ask for payment beforehand and no compulsion to pay if work is not up to your standards. Also, before I take you as my client, we will do a call - this helps me to have a measure at your expectations/requirements and helps to build a bond which is something I really value.
If you prefer - you could directly schedule a meet @ https://calendly.com/suvarnanarayanan2g/30min?month=2025-07
If you cannot make the slots to work for the calendar above, please shoot me an email and I will do a meet at a time you are comfortable with. Cheers!

Major Incident: Take Command before your IT hits the fan.
Hi, I’m Vincent — a one-man consultancy for service managers who need a second brain, a sounding board, or someone who’s seen worse.
With over a decade of hands-on experience in IT and Logistics operations, service quality, and process improvement, I help teams under pressure make sense of what’s actually happening, and what to do next.
Common reasons clients call me in: – Support is overwhelmed and nothing’s improving – Tooling, processes and roles are unclear, but nobody has time to fix it – Team leads or Service Managers are stuck and need a sparring partner – Leadership wants answers, and all you have is noise
This is call-a-friend consulting. Tactical. Direct. Remote-first.

The usual topics are various AWS services, Elastic Stack, Linux, wide range of troubleshooting, infrastructure as code, logging & monitoring, managing cloud costs, but I find it rewarding to venture into new areas together with the team.

Hey, I'm James! I have my company (OneVariable), and have 7+ years of embedded Rust experience, and 10+ years of embedded experience. I've been helping teams start using Rust, or scale up their use of Rust, through advising, training, and development assistance, as well as "Senior as a service" to help teams that are ramping up but still need help with questions around embedded/rust. Happy to help customers in EU and NA time zones.
Let me know if you need any help getting big computers talking to smaller computers!
I'm a data scientist, I'm looking for hard problems to solve. Hair on fire "This is causing lemon-law recalls and we can't solve it."[1] type problems.
I love avant garde problems, and have a pretty unique toolset (LLMs+KB, OR+ML, etc). I've worked with names you know in automotive, tech, and other spaces. Recently I've been working with Oil & Gas - Production estimates, pricing, and things I'm not allowed to talk about.
I've worked on projects including LLMs, knowledge extraction, automotive part failure prediction, translation, maintenance optimization, automated sports highlights, and more. I've also done some more interesting work including vehicle route planning in constrained environments.
Get in touch. Even if you're unsure, get in touch. Referals welcome. Email in profile.

Freelance Product & Technology Consultant with 20+ years of experience helping startups and mid-sized companies build and scale SaaS/web products. I specialize in MVP development, product-led growth, and modernizing legacy systems.
Notable work includes:
Designing MVPs that helped startups secure funding
Revamping infrastructure for real estate, sports, and publishing firms to cut costs and boost performance
Building AI/data-backed tools for decision-making and SEO-driven growth
I bring a business-oriented, collaborative mindset. Whether launching something new or fixing what’s broken, I aim to ship fast and drive real impact.
Looking for freelance or fractional roles — short or long-term.
I can provide the following for you:
- Product Design — Whether you need a design from scratch, a redesign, or you're having issues with a small part of your product, I can design it.
- Front-end Development — I can build the design into a pixel perfect product. This is rare among us designers and has proven to be extremely powerful for the result since there is less wasted effort. I've worked with a wide range of frontend and backend technologies and can hit the ground running on new projects. I pick up new tech quickly, which makes it easy for me to adapt to different environments.
- Analysis — Your users, know everything that's wrong with your product but have difficulty communicating it. Often it comes out in anger and frustration. That's where my usability analysis comes in. I'll review your app from an outsider and expert point of view, and give you actionable feedback.
- Free advice — You might not be sure if I am the right fit, and I very well might not be. I can help you figure out the best direction to go for free.
I take my work very seriously and put a lot of work into excellent communication, proper planning, and, last but not least, properly understanding your product so that we can produce great results.

Hello, I am Ken. About 4 years experience total. Most recent was at Dropbox, but the contract came to an end. While looking for a job, I am working on a couple of hobby projects, most notable of which is a new language in Go.
Currently working remote from Thailand (UTC+7), with potential for short on-site trips if necessary. Relocating to Australia soon(ish).
I have 20 years experience across a mixture of Ops/Infrastructure/Dev-Tools and web application architecture/development, with a focus on solving unique/uncommon problems.
I’m looking for opportunities to help companies with
- server infrastructure setup/maintenance;
- backend/server-side architecture & development (primarily PHP MVC);
- system integration;
I currently work remotely from Thailand, on a reasonably flexible schedule (I can schedule work hours to get overlap with most other timezones when required) but on-site visits to pretty much anywhere are a possibility if required too.

Like this Ask HN: Recommend employers with positive social impact [https://news.ycombinator.com/item?id=31518945], I am looking for similar work, but I am open to work on any interesting project. I am a European software developer who has lived and worked on four continents. Now it's time to move on and so I am in the process to relocate to Africa.
I have more than a decade of experience running a company, doing software development, support and training and mentoring adults and students, as well as working on educational projects, and I am willing to take on a mixture of roles as needed to support a project.
I value good teamwork over fancy tech, and I don't shy away from working on legacy code. I am primarily motivated by solving problems, so let me help you solve your problems.
I am open to work for companies anywhere as long as the work can be done fully remote from Africa.
While I could find a job elsewhere I believe that the experience living in an area where my work is going to have an impact gives me a better understanding of the needs of the location I am serving. Whether it is through direct contact with clients and users or just by being part of a local community and learning about the reality of living there.
In addition, I want to use some of my income to hire local interns and junior developers and train them in order to pass on my experience. I also sponsor children that otherwise can't afford to go to school (see my website). If you want to support this, I would love to work with you. Also if you are interested in hiring African developers yourself. I can help you build up your team.

Hi there! I'm Mark and I've worked alternately as an engineer and entrepreneur for fifteen years, in Beijing, in the SF Bay Area and remotely. Most of my work has been with smaller startup teams, but I've worked at a large scaleup as well. Experience building tech for education, real estate, automated trading, e-commerce and gig platforms. I also have some experience rescuing outsourced projects
I generally work in spurts 1-4 year spurts (either a single role or a series of contracts) and then take an extended break to learn new skills. Now looking for a contractor role at a 5-20 person startup. I prioritize learning and impact.

While I'm familiar with various technologies, my passion lies in programming with Rust. Whether it's backend development, blockchain, compilers, DevOps, embedded systems or mobile applications, I am totally onboard as long as there is a little bit of Rust involved.
For more information, take a look at my CV (https://c410-f3r.github.io/curriculum.pdf) or my GitHub account (https://github.com/c410-f3r).
I'm a jack-of-all-trades software engineer who's done extensive "founding engineer" work in the context of both VC-backed startups and for smaller contract gigs over a period of about 10 years.
I have strong technical foundations, good product sense, and have gone deep with AI/LLM tech both in the sense of being able to use it effectively, and in exploring the design space for products/tools leveraging it.
Tools I use most frequently these days: Typescript, node, React, pnpm+vite. I've also done extensive work with three.js in the past. I used to write a lot of Java and a bit of Objective C, have dabbled in Rust and Elixir.
I've done a lot of work in developer tools and data visualization of various kinds. Data-rich, non-traditional UIs with highly optimized UX, and rapid prototyping are my forte.

Full-stack software engineer with machine learning skills. I have a decade of experience building successful products for early stage startups and larger organisations.
Most of my experience has been developing new greenfield projects in contexts with significant uncertainty. I navigate this through careful consideration of stakeholder needs, business requirements, and an iterative approach. Beyond new projects, I have also worked extensively with a wide range of existing front-end and back-end systems. I get up to speed and can be effective quickly.
I am familiar with cross-functional teams of 5-10 people in design, product, and engineering roles. Alongside this, I have experience working with smaller select teams tasked with building the technical foundation of a startup.
I consider myself a “product engineer” in the sense that I focus on the product as a solution to end users’ problems, not a technical challenge. Over the years I have worked with many designers, user researchers, and user experience professionals who have shaped my attitude towards software. User experience is paramount to me and I can create effective user interfaces without aid of an existing design. My overall outlook is entrepreneurial and product-focused.
I have a GitHub with open source projects that have thousands of active users, and the bulk of an MSc in artificial intelligence.
Available for remote opportunities. I can accommodate flexible working patterns to suit different needs. I am also open to project-based work at a fixed price dependant on scope and complexity.
What I do:
- Lead greenfield projects, navigate ambiguity, and translate non-technical ideas into a technical product
- Innovate solutions to hard problems with high complexity that touch on areas such as algorithms or system design
- Design robust front-end and back-end systems, such as web apps with complex interfaces, or Serverless architectures
- Implement supervised, unsupervised, or semi-supervised machine learning techniques. Including use of LLMs and associated tooling
- Debug and fix bugs in existing software, including both front-end and back-end systems
- Collaborate and work with teams on existing projects

I’m a web and app developer with over 15 years of professional experience. I’ve worked at startups, mid-sized companies, and large corporations including Apple, eBay, and the Comcast Silicon Valley Innovation Center. Since starting my freelance business in 2020, I’ve done a lot of work with Rust, Stripe payment APIs, and multiple GPT/LLM APIs. I specialize in full-stack web development, but I’m also experienced in iOS development, server administration, database design, API integrations and more. I'm happy with both short-term jobs (alone or on a team) or medium-term contracts in an agile environment.

ABOUT:
Congratulations, you've turned an idea into reality, now it's time to scale. But how? You want someone who's your idea partner, a maker, a doer. But who?
I thrive in the chaotic in-between, wearing multiple hats and taking products from zero to market fit and scaling them to success. I've built and grew products at VEED.IO (Series A - Sequoia), Filmhub (Seed - a16z), Native Instruments, & many more.
If you don't waist time and you want more than the cookie-cutter slop, reach out & ship!

Hi. I'm Craig. I'm an experienced Senior Software Engineer, Systems Architect and Microsoft Certified Professional with a passion for software development.

I'm passionate about distributed systems design, CQRS and event sourcing and a proponent of domain-driven design to ensure that solutions are laser-focused on solving real business problems. I'm an open source enthusiast and advocate using the best and most appropriate tools available, providing for an effective and pragmatic solution that delivers genuine and quantifiable business value.

I am a seasoned (>13 years experience) full-stack staff-to-principal-level software engineer/consultant specializing in the backend, systems architecture, platform engineering, internal tools, prototyping, and data engineering. In addition to strong programming and architectural skills, I'm a force multiplier for any team in either role through the three T's -- teaching, talking, and tooling.
In the past, I've taught a number of scientists and students to code in python; I've led and managed a number of high-impact engineering teams of up to 12; and pioneered a number of no- and low-code solutions for stream processing, data model and query generation, form building, workflow systems, and front-end construction for a variety of industries, including those with strong regulatory requirements and complex business rules such as healthcare and fintech. >10% of all medicare applications and millions of individuals currently flow through pioneering no-code systems I conceived and built and have ran in production for over a decade
More recently, I've built a no-code automated form-filler and a workflow engine for coordinating LLMs and other generative AI processes, and on top of this a platform for both minimizing hallucinations and working with documents that are far too large for existing context window inputs or outputs using a novel, patent-pending process; and applied these tools to various contracted projects requiring analysis and and cross-checking of information and other forms of integrity across textual and video/audio corpus data in a variety of domains (fiction and non-fiction).
I am also an improvisational pianist, published poet, and I've created novel algorithms and tools for studying and composing both music and poetry.
I have extensive experience working for and running startups, software consulting shops, with some mid-sized company engineering experience as well; these give me a unique insight into speaking with customers and internal stake-holders, translating between engineering and other departments, gathering requirements, aligning stake-holders across departments on a vision and attainable timeline, and architecting/building/taking ownership over significant internal and customer-facing areas of responsibility.
If any of the above seems like a match for you and your organization or project, don't hesitate to reach out.
Technologies: Familiar with the entire ecosystem, including but not limited to TypeScript, Next.js, shadcnui, AI SDK, Expo, Tailwind CSS, Node.js, Prisma, PostgreSQL, Vercel.

I like to make GUI/backends that makes sense, are easy to understand (test with users) and performant/fast. Also to last years, with minimum dependencies.
I also have experience with live events setup for small broadcast of events, networking experience
I did tons of remote support with people around the world, also know how to use this information to make better programs (or design...).
I do not have any experience with AI.
Looking for 20-100 hours per month.

I'm experimenting with a new model for CS education using advisors who follow and adapt to students' interests. The core idea is that students should learn how to learn early and to self-direct their own education. However, they need support for when they get stuck.
At the moment, I'm looking to work with students who have deep interests in CS/tech, but want something more dynamic than a fixed curriculum program.
Experience: * Self-taught programmer. * Worked on data engineering at a large hospital. * Ex-VC - worked on technology due-diligence. * Started independent R&D lab (www.ithron.com). * Designed this model based on my experiences hiring engineers.
Engagement model: * Work with students 1 on 1 * ideal age range is 16-21, * 2-3 hours of meetings per week + 15-20 hours of self-directed time * 3 month batches, can be extended to a full-year. * More info at: https://www.divepod.to

I'm an experienced backend developer currently working for a large web hosting company, looking for a nights and weekends gig to learn new things and make a bit of spare cash.
I've got a fair amount of web development experience, I've written a ton of Go for my day job, I'm quite familiar with Postgres and MySQL and I've played around with Rust, Elixir, Zig, and C.
Because my primary motivation is learning, I have a "pay what you'd like" pricing scheme for my freelance work.
You contact me with a project, and if I accept it, you only pay me if I deliver something that has helped you, and you chose a price that reflects how much my work has helped you.
The one thing I do want, however, is feedback. If you didn't like it, you have to tell me why, with as much detail as possible. If you really liked it, I'd also appreciate you taking the time to tell me what your favorite parts were.
In terms of tasks, I'm open to anything, I'm mostly doing this to learn (although, obviously, money is nice too ^_^)
I’m a senior developer and infrastructure consultant with 15+ years of experience
— available for part-time work (24h/week). I help teams move fast without breaking things, bringing deep infrastructure expertise alongside strong full-stack execution.
What I Do Best:
• Cloud & Infrastructure: AWS (primary), Azure, GCP, Terraform, Kubernetes, Serverless, CI/CD (GitHub Actions, etc.)
• DevOps Workflows: Monitoring, cost reduction, zero-downtime deploys, secure secrets management, staging/preview environments
• Full-Stack Development: Node.js, React, React Native, Next.js, Tailwind, Postgres, MongoDB
• Delivery-First Mindset: Recently helped a client setup up CI/CD, staging, and production environments via Kubernetes — from scratch to deploy — in just 3 weeks part-time
What I’m Looking For:
Teams with meaningful technical challenges — ideally past the MVP/PoC stage and ready to do things properly. I’m most effective where there’s a need to scale infra, clean up dev workflows, or modernize architecture.
Engagement Style:
• Part-time (24h/week)
• Open to short/middle term high-impact contracts, retainers, or embedded support
• Happy to mentor as part of the engagement
Projects: • deepstream.io – Real-time messaging infrastructure (co-founder)
• pikku.dev – Open-source framework for building transport-agnostic TypeScript APIs
