What I'm looking for

I'm looking for senior backend engineering roles, remote or relocation, where I can take end-to-end ownership—from shaping the architecture to supporting production—and be accountable for the outcome.

At X5, I helped build the x5paket.ru loyalty subscription platform from its initial backend through growth to 350K+ active subscribers. I co-designed its architecture and recurring billing service, which reliably processed millions of transactions.

At ANNA Money, I automated complex compliance workflows for a UK fintech platform, enabling a new revenue stream and avoiding a projected 1+ FTE in operational overhead. I also developed integrations with Companies House and HMRC and owned L3 production incident investigations.

I enjoy taking end-to-end ownership, from understanding a business problem and shaping the architecture to deploying and supporting the solution. My experience includes distributed backend systems, event-driven workflows, recurring billing, and production LLM features.
