What I'm looking for

I seek senior engineering roles building scalable, high-availability systems with strong engineering practices, mentorship opportunities, and collaboration with international teams.

I am a Senior Software Engineer with extensive full-stack experience building scalable, high-availability systems using Java, Spring Boot, Jersey, JavaScript frameworks (Vue, AngularJS), TypeScript and Erlang. I collaborate with international clients, drive architecture decisions, mentor juniors, and deliver production-ready features for platforms serving tens of thousands of users with strong uptime and performance.

My background includes designing multi-tenant authentication, integrating payment gateways, improving release velocity through R&D and performance work, and maintaining high code quality via testing and reviews. I contribute technical writing on Java/Spring and build both professional and personal projects that demonstrate end-to-end backend and frontend expertise.
