What I'm looking for

I’m looking to own the hardest frontend problems end-to-end—microfrontends, performance, and accessibility—while partnering with product to turn evidence into outcomes like faster load times, better conversion, and durable engineering standards.

I’m a Principal Frontend Engineer with 10+ years designing and scaling high-traffic web platforms at Tesco, Upstox, and SAP. I specialise in microfrontend architecture, Core Web Vitals engineering, and frontend systems that compound into measurable business outcomes—doubled organic traffic, improved lead conversions by 60%, cut page load by 93%, and reduced cloud costs by 90%.

I operate at the intersection of deep technical execution and organisational influence: I author Architecture Decision Records, set cross-squad engineering standards, own frontend roadmaps, and grow engineers into senior and principal-track roles. From first principles through production at scale, I’ve delivered transactional performance improvements, built shared design systems, ran evidence-driven A/B experimentation, and led accessibility initiatives aligned to WCAG 2.1.
