What I'm looking for

I seek remote-friendly roles in EU time zones focused on billing/payments or infrastructure-heavy backend systems, with strong team collaboration and technical ownership.

I am a Senior Backend Engineer with 6+ years building backend systems, specializing in Ruby on Rails and payments-adjacent, data‑heavy domains.

I've designed APIs, state machines, and background processing for transaction-critical environments, improving reliability and handling complex money flows and edge cases.

I have hands-on experience decomposing monoliths into microservices using Ruby and Go, and I author open-source RubyGems used by the community.

I thrive in remote-first and early-stage teams, collaborate closely with product and DevOps, and focus on delivery, code quality, and scalable architectures.
