What I'm looking for

I seek senior backend or tech-lead roles where I can modernize legacy systems, design microservices on cloud platforms, mentor teams, and deliver scalable, secure solutions.

I am a senior Java software engineer with deep experience designing and migrating large-scale backend systems to modern microservices and cloud platforms. I specialize in implementing resilient APIs, event-driven integration, and performance-tuned data access layers.

Across telecom, banking, payments, rail and insurance, I led technical teams to deliver features for millions of users, integrate biometric SSO, and build anti-fraud and financial tooling. I have repeatedly modernized legacy systems (Delphi, Java portlets, JSF) to Spring Boot, Hibernate and containerized deployments.

My strengths include architecting microservices, migrating monoliths, and applying Kafka, Kubernetes and AWS to production environments. I also design cost-saving generic solutions and optimized SQL for complex business domains.

I bring leadership from tech-lead roles and hands-on engineering skills, committed to fast learning, self-driven improvements, and delivering measurable impact on reliability, security and operational cost.
