  • Migrated CRA to Vite + TypeScript and upgraded React 17 to 18, adopting concurrent rendering, route-level code splitting, and dead-code elimination, reducing bundle size by 50%, TTI by 40%, halving CI build times, and improving load times by deferring non-critical API calls and lazy-loading data.
  • Built an end-to-end POS loss-prevention platform for clients including Panda EPOS (5,000+ locations), surfacing live transactions and AI-detected CCTV exceptions with real-time alerts for fraud and shrinkage.
  • Built an in-house SDK for canvas-based ROI drawing and image overlay rendering, enabling precise event detection targeting across AI-monitored CCTV feeds.
  • Architected a shared component library of 30+ components with Storybook, WCAG 2.1 accessibility, and Jest/RTL coverage, adopted across 3 product teams and reducing UI defects by 50%.
  • Mentored 4 junior engineers through code reviews and pair programming; standardized CI/CD quality gates (lint, coverage, preview deploys), reducing production regressions.
