Senior Backend Engineer — Java · Spring Boot · Kafka

Senior software engineer with 11+ years of experience designing and building backend systems and APIs. I specialize in the Java/Spring Boot ecosystem, with hands-on experience in secure API design (Spring Security, OAuth2, JWT), relational data modeling and migrations (PostgreSQL, Flyway), and event-driven architectures with Kafka. I'm also comfortable across the stack, having worked on Angular front-ends that consume the services I build.

• 💰 algamoney-api — a Spring Boot REST API for personal finance management, with JWT/OAuth2 authentication, PostgreSQL and Flyway migrations.
• 📨 spring-kafka-payment-processor — exploring event-driven payment processing with Kafka and Spring.
