What I'm looking for

I seek roles where I can improve system performance and reliability, lead technical upgrades, work with modern Java/Spring stacks, and collaborate in Agile teams focused on measurable impact.

I am a backend-focused software engineer with hands-on experience improving performance, stability, and developer workflows across production systems. I have led database migrations, upgraded core platform dependencies, and applied TDD to raise code coverage substantially.

At Klika I delivered major efficiency gains—doubling product synchronization speed, cutting backend response times by 50%, and increasing test coverage from ~50% to ~80%—while upgrading the stack to Spring Boot and Java 21. At Zira I contributed to CRM enhancements, implemented SonarLint build checks, introduced view models and dependency injection, and led an Angular v12 to v18 migration that improved maintainability and UX.

I build reliable full-stack solutions using Java, Spring Boot, Angular, PostgreSQL and related tooling, embrace Agile practices, and prioritize measurable improvements in performance, stability, and developer productivity.
