Three I'd most like to talk about. Every project, with the details, is on the projects page.

• Running on alexandria2026s3ntryDeploys and monitoring for my homelabThe deployment pipeline and monitoring for alexandria.

There’s a live demo.Python · FastAPI · SQLAlchemy · SQLiteRead the details ->
• In daily use20261337Spaced repetition for interview prepA spaced-repetition tracker for the NeetCode 150. It schedules each problem for review after a day, a week and three weeks, paces me toward a deadline, and emails a digest every morning. Mostly built with Claude, and a tool I use daily rather than a portfolio piece.Python · Flask · React · TypeScript · SQLite · DockerRead the details ->
