Client Work & Builds

Creator of the Rex Framework

I built the Rex Framework to unify the full-stack experience.

Rex is my architectural solution to configuration fatigue. It merges React and Express into a single monolith where the frontend and backend share the exact same origin. By running Vite as middleware inside Express, it provides lightning-fast HMR while completely eliminating CORS issues and reducing setup time to under 60 seconds.
