About Me
Engineering that feels like craft.
I'm a senior software engineer specialising in website development, mobile apps, Chrome extensions, interactive experiences, AI integrations, modern UI/UX, automation and full stack development. I've shipped products to the App Store and Google Play, published extensions used daily by professionals, and built platforms that carry real revenue.
My work sits at the intersection of engineering rigour and design taste. I care about type safety, architecture and performance budgets as much as I care about easing curves, spacing and the feel of a hover state — because both are what make a product trustworthy.
Most of all, I enjoy solving complex business problems with elegant digital solutions. Tell me the outcome you need, and I'll design the system that gets you there — then build, ship and support it.
