About Me

I'm a Lead Frontend Developer with 7 years of experience building and scaling high-traffic web products. Most recently I led the frontend web team at SurveySparrow, where I owned everything from architecture and performance engineering to team leadership and hiring.

I've shipped full website migrations, driven Core Web Vitals from poor to 90–100 scores on a 1M+ monthly visitor site, built internal tooling, component libraries, and product websites from the ground up. I care deeply about performance, developer experience, and writing code that scales — both technically and as a team.

I've also conducted 200+ interviews and hired 10+ engineers. I've been writing code since well before the AI era — and now I use it to maximise what I can deliver.
