What I'm looking for

I’m looking for a Java role building high-load microservices where I can optimize performance, strengthen reliability with monitoring and integration tests, and help teams through code reviews and mentoring—ideally with CI/CD and containerized deployments.

I’m a backend/full-stack Java developer with 5+ years of enterprise and fintech experience across banking, automotive services, and EdTech. I specialize in high-load applications, microservice architecture, and performance optimization—improving critical modules by 15-20% and reaching over 85% test coverage.

In my recent role, I’ve built and supported high-load Java applications for internal banking needs and tax reporting automation, delivered REST API + Jmix UI functionality, and integrated Artemis MQ for asynchronous flows. I also focus on stability and quality through monitoring (ELK, Grafana/Prometheus), strong JUnit unit/integration testing, CI/CD with GitLab, and regular code reviews and mentoring.
