What I'm looking for

I'm looking to build responsive, reliable interfaces across mobile, web, desktop, and spatial surfaces, with ownership from architecture through release. I value performance, maintainable systems, real-time product experiences, and collaborative engineering teams.

I've built and shipped production interfaces for Hashbuzz, Pickload Logistics, Zidio Technologies, Dowell Technologies, and Sarutech Institute across web, mobile, and blockchain products. At Pickload, I rebuilt real-time tracking and communication experiences, contributing to an estimated 50% improvement in delivery speed and a ~90% reduction in payment-related support escalations.

I work across React, React Native, Flutter, TypeScript, Electron, and Three.js, owning frontend architecture from technical direction through release and iteration. I also lead teams, mentor engineers, and treat performance, maintainability, and human interaction as core product requirements.
