Experience

Co-founder & sole developer

Built online casino & sportsbook with 5 provably fair games (HMAC-SHA256), 5,000+ aggregated slots, and designed 500+ custom game card images served via Cloudflare's R2.
Rust/Axum backend with atomic financial transactions, Redis caching, and real-time WebSocket server for live bet feeds, chat, and spectating.
Implemented multi-cryptocurrency payment system (NOWPayments Custody API) with IPN webhooks, idempotent payout processing, and automated failure refunds.
Built SvelteKit frontend on Cloudflare Pages with edge-cached sessions via Cloudflare KV, and an admin dashboard with user management, revenue analytics, and feature flags.
Deployed on Hetzner VPS with GitHub Actions CI/CD, with automated PostgreSQL WAL backups to Cloudflare R2.

Built a custom launch monitor featuring a stereoscopic, dual global-shutter camera system and IR lighting, powered by an Nvidia Jetson Orin Nano.
Developed a real-time C++ application (CMake) using OpenCV for object tracking and ImGui to create a diagnostic UI for live data display and camera view control.
Implemented physics logic to test simple tracking data and calculate key metrics such as ball speed, launch angle, and estimated spin rate.

Developed and deployed a full-stack help queue dashboard, currently used by 5+ computer science classes serving 100+ students daily in my high school's CS department for over two years, as well as professors at universities like Carnegie Mellon.
Built the application using Next.js (TypeScript) for the frontend, with Firebase Auth for secure user authentication and Cloud Firestore for real-time data.
Designed a multi-role system (student, TA, teacher) for efficient classroom support and queue management.

Built an open-source, self-hosted affiliate tracking system with a Rust API and SvelteKit dashboard for monitoring clicks, conversions, and revenue across affiliate networks.
