What I'm looking for

I seek a role where I build impactful frontend products, mentor engineers, influence product design, and grow into technical leadership.

I am a Senior Frontend Engineer with extensive experience designing and building user interfaces and data visualisations for web applications. I have led frontend efforts at startups and established organisations, delivering production-ready products from concept to deployment.

My work spans React, TypeScript, Node.js and modern frontend tooling where I build full-stack MVPs, dashboards, and complex UI features. I regularly contribute to backend microservices and integrations when needed.

I have a track record of mentoring and recruiting junior to mid-level engineers, and I have held technical leadership roles including CTO, shaping technology strategy and driving engineering output.

I hold a BSc in Information Systems Sciences (First Class Honours) and I seek roles where I can deliver high-impact frontend experiences, influence product design, and grow engineering teams.
