About Roger

10+ years of backend and infrastructure experience, with a specialization in microservice and event-driven architectures.

I take ownership of complex, fast-moving projects end-to-end — combining deep technical knowledge with a solutions-first mindset. I stay current with modern best practices and bring the kind of autonomous, self-directed approach that lets teams move fast without constant hand-holding.

Whether you're scaling an existing system or building something new from the ground up, I focus on delivering robust, maintainable solutions that hold up as requirements evolve.
