Things I've built.
Tools, experiments, and shipped products. Source on GitHub — some with live demos.
Veil
Chrome extension that adds end-to-end encryption to any web messenger — AES-256-GCM, ECDH key exchange, zero external dependencies.
VoiceShield
Desktop app that anonymizes voices in video files — three presets, advanced controls, 100% offline processing with FFmpeg.
AuthGuard
Drop-in auth microservice — email/password, MFA, Google & Microsoft SSO, JWT with key rotation, session management.
Protest Match Bot
Telegram bot connecting travelers to protest rallies with supporters willing to fund their trips — built for the Iran solidarity movement.

Selenium bot that sniped a road test cancellation in 5 days instead of waiting 4 months — Python, browser automation, and a little patience.

CarX
Car-sharing API with Stripe payments, trip management, and user auth — containerized and deployed to AWS.
Fitness Tracker
Full-stack PHP app with auth, email verification, and recipe filtering — learned PHP from scratch for a college term project, no AI.
