01Index

Full-cycle engineering, from discovery to on-call.

For 7 years I have been building the parts of the internet that are not allowed to fail — high-traffic checkouts, event-driven backends, and AI systems that have to answer for themselves. I care less about clever code and more about systems that are still simple to reason about two years later.

Senior Software Engineer working across the full lifecycle: technical discovery, architecture decisions, implementation, deployment, monitoring and continuous improvement. Most of my work lives in Node.js, TypeScript and AWS, on top of event-driven architectures built to survive real traffic.

I work closely with product, design and QA, because the interesting constraints are rarely purely technical. I also mentor engineers, review architecture and run technical assessments — helping teams modernise legacy modules without stopping delivery.
