ABOUT

I bridge product goals and engineering delivery

Navigos Group operates VietnamWorks and NavigoSearch, the two largest job platforms in Vietnam. I've been building their employer-facing products since 2019: recruitment dashboards, candidate management systems, AI-assisted job posting workflows. Before Navigos, I built online learning platforms at EMG Edutech with Angular and NestJS.

The work mostly involves keeping large codebases productive as teams grow. On Navigos Talent One, I designed a state management system that lets 4 independent squads ship features on a 203K-line monorepo without blocking each other. On PRIMUS, I rewrote five fragmented React apps into a single Angular application because the legacy code was slower to patch than to replace. Load time dropped from 7 seconds to under 1 second.
