What I'm looking for

I'm looking to build and operate scalable backend and cloud-native services, solving performance, reliability, and distributed-systems challenges across the full production lifecycle.

At Klika-Tech, I developed and maintained production-grade backend services using Java, Spring Boot, MongoDB, and PostgreSQL.

I designed scalable REST APIs, distributed integrations, and business-critical components focused on reliability, fault tolerance, and maintainability. I also deployed cloud-native applications with Docker and Kubernetes across AWS and Azure.

Earlier, I built backend services for an enterprise geographic information system and led development of a high-load video streaming platform, including video processing and live, scheduled, and on-demand delivery.
