01 ABOUT

About

I got interested in programming at a young age and quickly fell in love: from websites, games and teaching tools into cloud infrastructure, data systems, WASM solutions, and full-stack products.

Most of my work sits somewhere between product and engineering. I’ve worked directly with clients on requirements, tracked down production data problems, designed APIs, and cleaned up interfaces that were harder to use than they needed to be.

I’ve also spent several years teaching computer science to more than 200 students and tutoring C/C++, Python, and Java. It taught me how to explain technical ideas clearly, notice where people get stuck, and build software that behaves the way people expect.

PYTHON / EDUCATION / BROWSER RUNTIME

pyDraw / pydraw.dev

pyDraw started as a graphics library and grew into a complete place to learn Python: documentation, a browser IDE, interactive courses, accounts, progress tracking, and workspace sync.

The runtime executes student code in a sandboxed Pyodide environment using Web Workers and cross-origin isolation. The surrounding platform adds local-first persistence, conflict-aware cloud sync, deterministic lesson feedback, and tests around the boundaries where application code meets untrusted user code.

JAVA / EDUCATION / GRAPHICS

javaDraw

A companion graphics API for learning Java. It keeps the setup small and the objects expressive so students can spend more time thinking about the program they want to make.

Terminal portfolio

The original version of this site, built as a terminal emulator in high school. It’s a little impractical, still fully functional, and worth keeping around.
