Some systems I've worked on: a voice chat service for the Brazilian market, the market leading open access e-Print server, e-business systems for car dealerships, wineries and a pallet recycling company, decision support systems for sales territory assignment, a collaborative visual editor for knowledge graphs, a social network for a secret society, a rich metadata database for the global performing arts with hundreds of Postgres tables that we should have built in RDF, a similarity metric for generic concepts (people, places, creative works, ...), a search engine for patents powered by a neural network, conversion of Freebase to an RDF graph with perfect referential integrity, an automatically curated collection of more than 1 million images of thousands of topics, a study of statistics of the sound of crumpling paper, and two efforts to commercialize foundation models before LLMs.

I served on a committee researching the application of OWL, RDF and other semantic web concepts to the ISO 20022 financial messaging standard which culminated in the publication of ISO/TR 22126-2:2025 "OWL representation of the ISO 20022 metamodel and e-repository"

My submissions to Hacker News are chosen by myself working together with YOShInOn, a smart RSS reader that couples a workflow engine with a BERT-based classification, clustering and recommendation engine.

Software-related side projects are going slow while I focus my effort on building up a large stock of photographs to post to my socials. These show up first here:
