About.

I'm an Engineering Lead focused on building reliable products, stronger teams, and better engineering environments.

My background combines hands-on product development, technical leadership, mobile delivery, and operational thinking. Over time, that has evolved into a broader interest in how engineering teams scale well, make better decisions, and build systems that stay effective as complexity grows.

I care about delivery quality, clarity of ownership, technical standards, and helping engineers do strong work without unnecessary friction. The through-line in my career has been moving from implementation into leverage: improving not only what gets built, but also how teams build it.

My strongest foundation is in frontend and cross-platform product engineering, especially with React, TypeScript, Next.js, React Native, and Expo. Around that core, I'm deliberately expanding my scope across API design, backend fundamentals, cloud architecture, and broader systems thinking.

Based in the UK, I'm shaping the next phase of my career toward engineering management: broader technical judgment, stronger organisational impact, and leadership that connects product delivery with team effectiveness.

I see engineering leadership as a balance of depth and range — being strong enough technically to guide decisions, and broad enough organisationally to help teams move with confidence.
