What I'm looking for

I’m looking for a senior engineering role where backend robustness and full-product ownership drive meaningful outcomes—building secure, scalable systems with strong architecture, reliable delivery, and measurable performance improvements.

I’m a senior full stack engineer with 11 years of experience designing and scaling distributed systems for fintech and enterprise SaaS platforms across Europe and the Asia-Pacific region. I’ve led backend modernization at WebTown, cutting API response time by 47% and sustaining 3M daily requests at 99.97% uptime. At Xurge Digital Lab, I led a team of 6 engineers building a secure, multi-tenant messaging and financial data platform, reducing message delivery latency by 62% while supporting up to 500K concurrent sessions.

My work consistently connects the data layer to client-facing outcomes, with deep expertise in TypeScript, Node.js, PostgreSQL, and AWS. I’ve built multi-tenant APIs with NestJS and role-based JWT authentication, delivered GraphQL reporting consumed by 40+ enterprise clients, and improved test coverage from 28% to 79% through TDD and CI/CD. I’m especially driven by backend robustness and full-product ownership—delivering secure, reliable systems that teams and enterprises can depend on.
