What I'm looking for

I seek frontend or fullstack roles where I can lead feature delivery, improve performance and reliability, mentor engineers, and build maintainable agentic tooling.

I am a Senior Software Engineer with 9+ years of commercial web development experience, focused on frontend technologies like React, Next.JS and NodeJS. I combine hands-on engineering with technical leadership and product-focused thinking.

I've led feature delivery from product documentation through technical specification and execution, driven performance and bundle-size improvements, and conducted technical R&D and PoCs including ServiceWorker usage and monorepo/web components experiments.

My work spans streaming (HBO Max), ML platform tooling (Determined AI / HPE), biomedical products (Elsevier DDI Risk Calculator) and analytics platforms, where I improved reliability, testing, and observability while mentoring engineers.

I also work as an independent contractor building and maintaining agentic tooling, automation and workflows, emphasizing code quality, performance optimization, testing and maintainability.
