Full Stack Developer at Hue Technologies building a two-sided marketplace backend with hardened authentication and Stripe billing.

At Hue Technologies, I architected the production TypeScript backend for a two-sided marketplace using Bun, Hono, Prisma, PostgreSQL, and Redis. I hardened authentication and rate limiting, shipped Stripe subscription billing, and resolved documented race conditions.

Previously, I built a React Native client and Node.js backend from scratch at Consul Inc, and owned iOS and Android delivery at Nexmedis. I also teach React Native and React.js bootcamps at JValley.
