What I'm looking for

I seek senior backend roles where I can design scalable Java-based systems, lead small teams, improve CI/CD and performance, and work in collaborative, delivery-focused environments.

I am a Senior Backend Java Developer with 21 years of hands-on experience designing and delivering production-grade backend systems across video streaming, CRM, photo hosting, and web-based equipment management. I specialize in Java, Spring Boot, Spring Data, Hibernate and relational databases, delivering robust API designs and backend services with strong emphasis on code quality and test coverage.

I have led small teams, designed system architecture, implemented CI/CD pipelines, and optimized performance—improving services by measurable margins such as 20% performance gains and dramatic reductions in manual work and release times. My work spans on-premise and AWS deployments, containerized environments, and orchestration with Kubernetes.

I value clear solution design, cross-team communication, and knowledge sharing; I aim to build maintainable systems that reduce operational overhead and accelerate business processes through automation and thoughtful architecture.
