AI-powered learning platform

A study system that turns Markdown lessons into interactive cards, AI-generated quizzes, and a progress dashboard.

Lesson pipeline: Detects new Markdown files, parses their structure, and creates searchable lesson sections.
Three study modes: Read full lessons, review flip cards, or answer generated quiz questions with explanations.
Smarter review: Tracks progress and uses spaced repetition to bring concepts back at useful intervals.
Full-stack system: A React front end connects to an Express API and SQLite data model for lessons, quizzes, and attempts.

How I work

I start by listening.

Before engineering, I worked in enterprise software sales. That taught me to ask better questions, explain tradeoffs plainly, and pay attention to what people actually need.

I bring that into product work now. Retro games, pixel art, music, and animation influence how I design, but the thing still has to be useful.

Applied AI

I turn models and research into products people can test, learn from, and trust.

Full-stack products

I take ideas from an early sketch through the database, interface, testing, and launch.

Freelance websites

I design and launch thoughtful websites for local businesses, independent clients, and community groups.
