Full-Stack Product Engineering

Frontend-focused full-stack delivery across product interfaces, APIs, dashboards, and polished web experiences — from system design through launch-ready implementation.

Rezerv

A booking and membership platform for 1,000+ fitness, education and entertainment SMBs - from the admin calendar to a no-code storefront.

Lime

Virtual Office Platform

08

A virtual office for small studios - an office floor with voice rooms, chat, projects and approvals in one TypeScript app.

The future isn’t just chat.

AI is the new interface — but intelligence alone isn’t a product. The craft lives in the flows, the edge cases, and the details that turn a clever demo into something people trust every day.

About me.Designing for what’s next.

Full-stack craft. Frontend taste.

I'm a senior full-stack engineer with 5+ years architecting and delivering AI-integrated web platforms, enterprise dashboards, and consumer products across Southeast Asia and Singapore. I led frontend engineering for an AI-driven ERP platform, and I'm currently freelancing — building LMS platforms, interactive games, and AI image-generation services for remote clients. I specialize in React/Next.js, TypeScript, and LLM integration.

I like the hard middle of product work: shaping ambiguous ideas, building the interface system, connecting the AI or backend layer, and polishing the path until people can trust it.

My current focus is AI-integrated product work — using LLMs to amplify the craft and collapse the gap between idea and execution.
