At Carousell ChoTot, I accelerate delivery through a Spec-Driven Development workflow and AI coding assistants, while building scalable, high-performance product systems.

I led migration of 20+ app modules to SwiftUI, transitioning 65% of the codebase, and architected a SwiftUI car-inspection app with Combine and Realm that digitized offline field workflows.

Previously, I built real-time iOS streaming and multi-camera calling platforms at Est rouge, inc, and led five iOS developers at Sun*, improving stability and reducing crash rates by 99.9%.
