chadworks is a one-person web studio run by me, Chad Lewine. I build custom coded websites and platforms for motivated individuals and organizations that want to double down on authentic digital presence as a counter measure to social media burnout and AI saturation. Every build is written from scratch. No Squarespace, no Wix, no Divi, no Elementor, no templates (unless a template makes sense.)
Recent:
- Rising Compass, https://risingcompass.net - reads popular music against a published rubric and sorts it by the messaging contained in the lyrics
- Chad Lewine, https://chadlewine.com - World's most immersive artist website
- The Illus Caden, https://illuscaden.com - independent publication, custom WP theme
- SFVV, https://demos.chadworks.co/sfvv - freeing the vertical scroll from the clutches of big tech so brands can use the format on their own website.
Twenty years building for the web.

Background:
- coding since 2010, 6+ years working for startups & scaleups, generalist engineer with strong fullstack experience
- contributed to a few open source projects, reported critical vulnerabilities on a bunch of major websites
- worked across web, mobile, AI, security, automation and scraping
Currently bootstrapping an AI product, so I'm ideally looking for part-time/freelance work, unless the product is truly interesting and/or beneficial to society (climate change, healthcare, education...)
SEEKING WORK | Remote
Location: Los Angeles, CA and San Francisco, CA
I'm a seasoned generalist with deep focus in certain areas such as game development, performance engineering, systems engineering, low-level engineering and embedded software.
What I shipped this year for money: Performance improvements to HFT code (Rust & C++) for financial trading. Firmware for the hardware of an ereader (Rust+ARM).
Current side-project: Deep internals work on VS Code Web: using quilt to maintain patches against upstream, extending it with inline agent panels and custom completion providers, backed by a bespoke C# server replacing the Node.js REH with my own dedicated server - similar in spirit to Coder's Code Server or OpenVSCode-Server.
Technologies: kernel drivers, systems engineering, video games, AI, LLMs, caching, graphics, rendering, assembly languages, generative AI, heavy focus on back-end systems, and to a lesser degreee, full-stack.
- Languages: C++, C, C#, Go, Rust, TypeScript, JavaScript, Python, Ruby, Lua, + more.

Currently in South America and planning my move back to the US once a role is secured (whether in San Francisco or another city) to avoid relocating twice.
Due to high interest in my work with recursive self-improving coding agents, I've shared an example repo at https://github.com/adam-s/agent-tuning. I'm always open to discussing how I optimize agents for complex, repetitive workflows.
I bring 13 years of full-stack UI development experience alongside deep expertise in browser automation and agents, which I've been engineering since 2018. This blend makes me particularly strong in QA automation engineering, browser automation, and complex frontend architecture.
Notable projects include custom legal document management dashboards and a drag-and-drop CRM email builder for social marketing campaigns. As a consultant and full-time engineer, I’ve led 0-to-1 product development across fintech, streaming, real estate, edtech, marketing, and media. Having worked at companies ranging from a 130-person AI organization to a scrappy 7-person team, I thrive most in fast-paced, high-ownership environments.

Hands-on engineer and former Head/VP of Engineering with 15+ years of experience across software engineering, AI/LLM systems, backend and full-stack development, distributed systems, platform and cloud engineering, architecture, and production delivery.
I am a backend expert, having built and maintained mission critical, low latency and highly available systems for many companies over the last 10 years, in addition to over 20 total years of software development experience. I learn new things extremely quickly. AWS preferred but not required (I hold a variety of certs, available here: https://www.credly.com/users/jon-north.ad78f0c8)
You will like working with me because I:
* hold your goals as my priorities
* communicate verbosely yet synthesize well
* my rates are reasonable in exchange for the value I deliver
* I guarantee I will get the job done
* built the primary streaming data architecture for realtime game player tracking information (all games, 50ms SLA) and game stats for one of the top 3 US sports leagues (can’t name drop!) using Redpanda/Kafka on Azure+Terraform, and implemented its developer portal using Gravitee to provide first class streaming API support and monetization. Also built, deployed and maintained their ask-a-question-get-a-true-answer AI bot to expose 20+ years of stats to natural language fan questions! (this was the third of currently four times I’ve built similar architectures for different companies)
* Implemented a vector DB for one of the leading AI image hallucination platforms (millions of users) to provide an image similarity service.
* replatformed dozens of complex quant jobs to AWS Lambda for a startup hedge fund (~$1B AUM), vastly improving QoS and maintenance cost. Line 1 to platform-in-prod time 3 months, including refactoring for fit. This was mission critical cannot-fail stuff and required extensive proof of correctness.
* built a framework to collapse dozens of singleton ETL programs into one config-driven, simple C# application performing the same functionality at ~80% reduction in maintenance cost year over year.

I have a deal for you:
1. Your monthly cloud hosting bill goes down. 2. You get an experienced DevOps engineer to manage your infrastructure, optimize things, and be on call, all included in that smaller bill.
That is it. Interested? mail to: contact@jordanschatz.com
Long time experienced DevOps engineer. I hate systems that are slow, expensive and hard to change. If you do to, let me know ;)
