What I'm looking for

I want to lead Java microservices and Big Data projects in an Agile team—designing systems on AWS/Kubernetes, improving quality with testing and code reviews, and delivering real-time capabilities.

I’m a Skilled Lead Software Engineer with over 11 years of experience designing, developing, and maintaining complex software systems, primarily with the Java technology stack. I focus on microservices architecture, Big Data integration, ETL, and cloud infrastructure management using AWS and Kubernetes, and I enjoy taking ownership across full-stack development with technologies like Spring Boot, Kafka, and modern front-end frameworks.

I thrive as a team leader—implementing Agile methodologies, strengthening code quality through rigorous testing and code reviews, and guiding delivery from architecture to production. I’ve also built and migrated systems around ClickHouse and real-time reporting, improved authentication and security with JWT-based approaches, and contributed UI and business logic work in major enterprise products (including open source contributions to Apache Syncope).
