Software DeveloperI'm a Software Developer who has worked with local and international startups. Since December 2025, I've freelanced for Singapore-based clients. I plan the work, AI agents build it, and I set the checks it must pass. Building software is still the part of the job I enjoy most.
Experience
FreelanceDecember 2025 - Present
Software Developer, AI agent workflows- I ship live web apps for Singapore-based clients. I have been lead developer on 4 of them: Catalyst Time Tracker, Catalyst Hiring, AdLauncher and the MoneyBees site. I am a core contributor on 2 more: Catalyst Workspace and SearchBlueprint.
- I build with Claude Code and Codex agents. I write the plan and the task specs, and I set the checks each change must pass. Several agents build at once, and each builds into its own folder.
- Each task in the queue carries a tag that sets its checks. For a [PLAN] task, 2 to 3 agents read the code first, and a reviewer agent approves the plan. Before a nontrivial change ships, two more reviewer agents read only the change. They have no memory of how the code was written.
- My stack is React, TypeScript, Next.js, Tailwind CSS, shadcn/ui and TanStack Query. The backends run on Supabase (Postgres, RLS, Edge Functions). I also ship a Python desktop app for Windows and macOS.
- The build must pass before every commit. UI tasks tagged [TEST] get a Playwright check in a real browser at desktop and mobile widths, then a QA agent signs off. Vitest suites cover the logic. On the live Catalyst apps, a task is done only after a check on production.

Technical Skills
Backend DevelopmentI have experience building backends using Laravel, creating APIs, integrating WebSockets, and managing databases with MySQL and PostgreSQL in various projects. Frontend DevelopmentI’ve worked on several projects using modern frontend frameworks like React, Vue.js, and Next.js. I’ve also utilized UI libraries such as Vuetify and Tailwind CSS for building responsive, user-friendly interfaces. Development ToolsI use Git and GitHub for version control and Vercel for deployment. I build with Claude Code and Codex agents. I set up the rule files, task queues and skills they work from. A skill is a set of reusable task instructions. Agents apply Supabase migrations through its MCP server, a direct tool connection. I test with Vitest and Playwright. I also build AI features with the OpenAI API.
