01 / About

About me.

I'm a full-stack developer at Danphe Innovations, where I work on Optonome, a workforce platform serving more than 2,000 users, including around 200 concurrent users. I develop APIs, web applications, and React Native features.

I've also worked on Next.js projects using server-side rendering (SSR). I maintain a legacy PHP application and supported its upgrade from PHP 5 to PHP 8, along with a database migration from MySQL 5 to PostgreSQL 15.

I build real-time messaging, offline features, integrations, and deployment workflows. I reduced one MongoDB query from about 30 seconds to 5 seconds and helped lower AWS costs by roughly $280 per month. I also build mobile apps and small projects in my spare time.
