What I'm looking for

I seek impactful roles building scalable frontend-first products within collaborative, engineering-driven teams where I can lead architecture, mentor engineers, and deliver high-performance user experiences.

I am a Senior Fullstack Engineer with over 15 years' experience delivering software across banking, e-commerce, and cybersecurity. I focus on frontend excellence with deep expertise in React, Next.js and TypeScript while also architecting backend microservices and scalable systems.

My recent work includes developing a global recruitment platform using Next.js, TypeScript, Node.js microservices and a GraphQL BFF in a serverless AWS environment, and leading a migration to a modern React stack that delivered significant performance improvements for a major bank.

I mentor teams, drive clean architecture and DevOps practices, and consistently deliver projects on time and within budget by combining pragmatic engineering, strong testing and CI/CD discipline, and a user-focused approach.
