Lead Software Engineer Open Government Products

• Evolved OGP’s internal design system into oui, an SSR-compatible successor with 36+ accessible components for Next.js App Router — now the default design system for newly created products across the organisation.
• Diagnosed ask.gov.sg’s end-of-life framework as a maintainability and open-source risk and led a 4-month rewrite through influence rather than positional authority — zero regressions, with measurable performance and SEO gains; the architecture patterns became the org-wide Starter Kit.
• Inherited maps.gov.sg as a hackathon POC and hardened it with queuing, auth middleware, and rate limiting — sustaining 20× growth (25k → 502k views) with no app-level incidents before a clean handoff to a dedicated team.
• Built an internal CLI tool that replaces multi-day manual infrastructure provisioning, generating isolated, production-ready AWS environments with CI/CD in ~10 minutes — now the standard for new product infrastructure.
• Embedded in the Isomer rebuild to set up engineering foundations: CI/CD, Storybook and Chromatic for design–engineer handoff, and lightweight ADRs — practices that persisted after handoff.

Senior Software Engineer

• Tech-led MyActiveSG+ end-to-end, building a one-day prototype that secured internal buy-in and countered a vendor lock-in (saving ~S$12M), and drove it through two pilots to public launch at ~150k bookings/month at handoff.
• Led the zero-downtime migration of FormSG’s frontend from AngularJS to React 17, eliminating a critical maintenance liability while keeping the service live throughout.
• Authored OGP’s internal design system (adopted by 70% of live projects) and the starter kit template used to bootstrap 70% of all products in 2024.

Software Engineer

• Led the full TypeScript migration of FormSG’s REST API, refactoring to RESTful conventions with end-to-end type safety across the backend.
• Built the clinician-facing frontend for Singapore’s national COVID-19 vaccination appointment system — the primary interface for clinic staff managing patient vaccinations at scale.

Software Engineering Intern G o o g l e

• Interned for 14 weeks as part of the Google Pay team in Singapore
• Completed and had full ownership of one new feature in the Android application, including but not limited to high level architecture, design decisions, implementation, and testing
• Work closely with peers to ensure good architectural design and strong software engineering principles in code commited
