// About Me

WHO I AM

I'm Jasper — a full-stack web developer and published npm author building production-grade web and mobile apps. I work across the stack: React and React Native (Expo) on the front end, Node.js/Express and .NET on the back end, and Firebase and AWS in the cloud.

Right now I'm building ERP, authentication, and QR-verification platforms at Lumina Tech. I've validated AI training data with RAG pipelines at MineBright, applied XGBoost to transit-ETA prediction for my thesis, and shipped freelance products end-to-end. I care about clean code, strong security fundamentals, and software that solves real problems.
