About
I’m a software engineer based in Singapore who enjoys building production-grade web and backend systems, then shipping them end-to-end with solid testing, CI/CD, and performance in mind. Recently, I’ve been contributing to a two-sided food marketplace where I worked on a Node.js REST API using ORMs and validation, designed robust server-side pipelines for personalized discovery, and ensured reliable delivery from pre-launch to rollout.
I also collaborate across teams to deliver polished user experiences—revamping company sites with Vue.js, CMS integrations, and SEO improvements. Prior to that, I engineered mobile experiences and supported game/product development using React Native and React-based tooling, while working on internal frameworks and delivery workflows to improve UI development speed and overall engineering productivity.

Built and shipped a production-grade REST API on Node.js with a full backend stack (ORM, PostgreSQL, schema validation, and automated integration tests). Delivered the service from 0 to pre-launch within four months and engineered a multi-stage, server-side personalized discovery pipeline using distance/affinity-based scoring and stateless cursors for efficient pagination. Set up GitHub Actions for backend coverage, linting, TypeScript checks, database integrity checks, and test coverage on every pull request.
Migrated a corporate website from WordPress to Astro, acting as the sole developer to improve page load performance and modernize the codebase over a two-month engagement. Set up CI/CD using GitHub Actions to automate linting, formatting checks, and deployment to GitHub Pages on every push. Implemented technical SEO foundations including sitemap generation and Google Search Console indexing so links appear in Google search results.
Revamped and integrated the company website to improve aesthetics and user experience using Vue.js, CSS, and HTML with CMS platforms such as HubSpot. Partnered closely with UI/UX designers and product managers, increasing client engagement and improving site load times. Implemented SEO optimizations aligned with Lighthouse and best practices to improve search engine rankings and organic traffic.
