About me

Engineer at heart,
craftsman by practice

I'm a Senior Frontend Engineer with over 6 years of experience shipping high-quality React applications across healthcare, e-commerce, and enterprise software. Holding an MSc in Advanced Software Engineering from the University of Strathclyde, I combine academic rigour with deep production instinct.

My work spans from architecting entire frontend systems as a sole engineer, to leading teams building AWS cloud-native applications. I currently lead frontend development at DrugStoc, and have previously shipped across Trilogy's portfolio of cloud platforms.

I believe great frontend is about more than visual output — it's about systems thinking, predictable component contracts, and building interfaces that scale without degrading. I care deeply about performance, state predictability, and measurable UX outcomes.

Component architecture that scales without drift
State management with clarity and minimal side-effects
Performance as a feature, not an afterthought
UX driven by empathy for the end user
