Selected work

Video Studio

Problem
Managing large video libraries usually means waiting minutes for media indexing, fighting fragile transcode pipelines, and jumping between separate apps just to compress, trim, upscale, or find a spoken quote.
My role
Sole engineer
Stack
Python, Cython, FFmpeg, WebAssembly, WebCodecs
Result
Compresses, trims, joins and checks your own videos with nothing to install, and the files never leave your device.

Vox

Problem
Modern web apps force teams to write the same data structure four times—in database migrations, backend models, API validators, and frontend types—creating bugs every time a field changes.
My role
Creator and lead engineer
Stack
Rust, Compiler design, Code generation
Result
Lets humans and AI coding assistants build complete, type-checked web applications in a single `.vox` file with APIs that stay in sync and strict compile-time error handling.

GigMe

Problem
Job boards flood people with keyword-matched listings without telling them which skills they are actually missing or whether their application strategy is working.
My role
Sole engineer
Stack
TypeScript, PostgreSQL, LLM extraction, Ranking
Result
Guides you through focused modes for career discovery, mock interviews, skill practice, and application tracking, while aggregating public role and compensation signals.
