At Scissero, I built a Jest testing solution powered by a PDF-to-JSON validation algorithm that reduced production errors by 90%. I also built workflow helpers in a Node.js API that cut debugging time and task completion time.

At HiveFuse, I built a full-stack healthcare application with React and NestJS that helped secure the company’s first clients. I also optimized a user-data endpoint with Redis caching, reducing response latency from 200 ms to 30 ms.
