JonathanSolvesProblems/README.md

Jonathan Andrei, Senior Full Stack Developer. github.com/JonathanSolvesProblems and jonathansolvesproblems.com. Python, TypeScript, React, Next.js, LLM Agents, RAG, AWS.

I'm looking for a few Android beta testers right now (through September 2026, for the RevenueCat Shipaton).

I'm shipping Cooldown, a wishlist that saves you money by making you wait: add something you're tempted to buy, let it cool off, and watch the money you didn't spend add up.

If you have an Android phone and two minutes: sign up (your email stays private) with this quick form, I'll add you, then opt in to the closed test. Thirty-second demo. Happy to test yours back.

I build software that actually ships. Most of what is below started as a deadline and ended as something that runs, against real data, in front of real users.

I work mostly in TypeScript and Python, lately on AI agents and developer tooling, and I care more about whether a thing survives contact with real input than about how clean it looks in a diagram.

I take on project work: AI agents, RAG pipelines, developer tooling, and integrations. Details and selected work at jonathansolvesproblems.com.

How this page keeps itself current

The board is not a third-party widget. It is an SVG this repo generates from my own push history, so it reflects what I actually touched last rather than a static image I updated once and forgot.

scripts/build_profile.py     queries the GitHub API, renders both themes, rewrites the table
scripts/build_banner.py      renders the banner from assets/portrait.png
assets/board-*.svg           dark and light boards, swapped by prefers-color-scheme
.github/workflows/           re-runs the generator every Monday and commits any change

Run python scripts/build_profile.py to refresh it by hand.
