About

I'm a Senior Frontend Engineer with 9+ years of experience building large-scale web products that directly impact revenue, seller growth, and user experience. Currently at Carousell — one of Southeast Asia's largest C2C marketplaces — I own end-to-end frontend delivery for seller monetization and professional account platforms, working across React, Redux, and TypeScript on products used by millions of sellers across SG, MY, HK, TW, and PH. Before Carousell, I spent 4+ years at Works Applications in Singapore, leading frontend development for enterprise-grade Supply Chain Management and E-Commerce systems, collaborating with cross-functional teams across multiple countries. What sets me apart: 🚀 I go beyond the scope. I delivered a full analytics dashboard that exceeded the original brief — adding a responsive mobile web version on top of the planned desktop-only build, without compromising quality or timelines. 🤖 I build AI tooling for my team, not just use it. I designed and rolled out a GitHub Copilot workflow and AI agent instructions that helped my team cut integration test writing time by up to 60+ minutes per file — with a 100% recommendation rate from engineers who adopted it. I'm the engineer who introduced and scaled AI-assisted development practices across the team. 🤝 I go beyond the ticket. I mentor engineers, contribute to shared design systems, platform migrations, and actively shape engineering practices at both team and org level. Tech I work with: React · Redux · TypeScript · React Testing Library · Angular · GitHub Copilot · Mobile Web · Desktop Web
