Services

Whether you're hiring for a role or scoping a project, here's where I can help. Every service is backed by shipped work you can review.

Full-stack Web Development

My core discipline. I build complete web products from database schema to responsive UI: REST APIs with Spring Boot or Node.js, front-ends with React and Next.js, authentication and role-based access control — ready to have AI features plugged in.

AI & Automation

AI integrated into the product, not bolted on: chat over your documents, agents that call your APIs, and automated workflows that remove busywork. Built on retrieval so answers come from your data — and wired into the same full-stack apps I build.

Mobile App Development

Production-ready mobile apps built from Figma with pixel accuracy. I build in React Native and Flutter, integrate REST APIs and Firebase, and care about the details that make an app feel native.

UI/UX & Product Design

Hands-on UI/UX experience from designing a multi-platform POS system for a Singapore brand. I map user flows, build design systems, and create interactive prototypes — and because I'm an engineer first, every design is grounded in what can actually be built.

Quality Assurance

Hands-on testing experience on production apps used by companies in Singapore. I test the critical paths — auth, permissions, payments, reports — and document bugs developers can actually fix.
