What I'm looking for

I seek senior backend or architecture roles where I can design scalable Java/Spring systems, lead teams, drive CI/CD and deliver measurable business value.

I am a Senior Java Architect and Technical Lead with extensive experience designing and implementing Java 17 and Spring Boot solutions, focusing on microservices, Maven multi-module architectures and WildFly deployments.

I have led backend development for enterprise clients, building APIs with Spring Boot, Spring MVC and Apache Camel, integrating data stores such as PostgreSQL, Snowflake, MongoDB and Dynamo, and implementing CI/CD with Git, Jenkins and Concourse.

My work emphasizes automated testing (JUnit, Mockito), messaging (Kafka), cloud platforms (AWS), containerization (Docker) and pragmatic agile delivery—consistently aligning architecture and sprint execution to client objectives.
