What I'm looking for

I'm looking for a remote or on-site opportunity in Europe where I can build maintainable, high-performance web applications across frontend, backend, APIs, integrations, and cloud infrastructure.

I'm building scalable third-party integrations at Reva, creating API clients and data synchronization pipelines while modernizing legacy systems.

I've improved performance through query optimization, batch processing, and resilient background jobs, while expanding automated test coverage to support reliable deployments.

At HiVelocity, I built Vue and TypeScript web applications, reduced the bug backlog by 20%, and created reusable components that cut code duplication by 40%.

I've also delivered React components at Kammeko, optimized real-time dashboards at Cesanta, and mentored new developers as a LeWagon teaching assistant.
