Small, focused tools, mostly Python, shipped and public.
One API and a YAML manifest for running SQL across Oracle, PostgreSQL, and pgduckdb — transactions, retries, execution-plan capture, and alerts to Discord/Telegram when something breaks. Grew out of actually needing this at LabMA.
A zero-dependency CLI that checks Markdown citations against arXiv, Crossref, and OpenAlex — catches fabricated references before they ship into a report or a paper draft.
A native desktop flashcard app — FSRS spaced-repetition scheduling, KaTeX math rendering, no Electron. Built because I wanted spaced repetition for math!
A RAG pipeline for talking to a webpage — chunk it, embed it with FAISS, then ask it questions through a Telegram bot. Kinda old, was made in 2024, so lots of old tools =)
