About Me
Software Engineer with 3+ years of experience designing and building scalable web applications across finance, government, and edtech sectors. Strong expertise in React, TypeScript, and modern frontend architectures, combined with hands-on backend development using NestJS and PostgreSQL.
Alongside my day job I have built and shipped three products: Teachi, an AI lesson-planning platform for tutors; Danaangi, a multilingual QR menu SaaS for restaurants; and KIRA Prints, a photo-print store with its own production back office. All three are live in production.
I take on freelance work where that experience helps: building an MVP end to end, adding AI features (OpenAI, document import, AI-assisted editing) to an existing Next.js app, or cleaning up a slow React front end. I have worked with teams in Singapore, China and the US and write clear async updates.
