What I'm looking for

I’m looking for a team building modern SaaS products where I can own full-stack features end-to-end, collaborate across design and engineering, and keep improving frontend quality—while exploring AI-assisted development workflows.

I’m a Full-stack Software Engineer with 10+ years’ experience, and I focus on building software that is useful, well-built, and pleasant to use. I enjoy web technologies—especially frontend development—and I also love creative coding and side projects.

Recently at Infinity Tracking Limited, I’ve worked across customer portals, analytics dashboards, public APIs, backend services, and legacy systems. I built and maintained customer experiences for call activity, attribution data, and reporting, and I worked on the browser-side tracking layer used on customer websites. During a platform migration, I built new Vue.js features inside a legacy Ember.js and Symfony portal, and I also deployed serverless backend services to move away from legacy PHP functionality.

Earlier, at the Hong Kong Observatory, I created a full-stack scientific modelling system for departmental users, translating requirements into workflows for meteorological and radiological assessment. I also developed internal tools for map-based visualisation, reporting, and controlled access, plus documentation and user training. Before that, I delivered enterprise web frontend components at PCCW Solutions, and built education-facing robotics and face-recognition features while working on a programme portal at the Vocational Training Council.
