About Me

I'm a full-stack software engineer on the founding team at Voltade, where I build production AI systems for enterprise clients. I've worked on everything from supplier intelligence platforms and WhatsApp-integrated chatbots to OCR invoice processing and a no-code AI agent builder.

My go-to stack is TypeScript everywhere: React on the frontend, Hono on the backend, PostgreSQL + Drizzle for data, and OpenAI/Anthropic for AI. I care about shipping fast, writing clean code, and building things that actually get used.

Currently finishing my double degree in Computer Science and Economics at NTU Singapore (CGPA 4.5/5.0). When I'm not coding, I'm probably playing CS2, at the gym or hunting for good food.
