What I'm looking for

I'm looking to build reliable, scalable backend systems where I can work on Java, Spring Boot, system integration, asynchronous processing, and performance optimization alongside cross-functional teams.

I've built Java backend services for enterprise applications, including a Change Data Capture service at Andersen Lab that decoupled search indexing and reduced RAM usage sixfold versus the legacy Logstash pipeline.

At Andersen Lab, I also delivered parallel Excel import pipelines that saved marketing teams an average of six hours weekly, replaced legacy email handling with RabbitMQ processing achieving 99%+ reliable single delivery, and collaborated on build-cache improvements that reduced average build times by 40%.

Through freelance work, I've developed REST APIs and microservices with Java, Spring Boot, and PostgreSQL, using RabbitMQ for background tasks and webhooks. I work with Hibernate, JDBC, QueryDSL, OpenAPI/Swagger, JUnit, Mockito, and Docker to create maintainable, documented backend systems.

My background in control and automation engineering, along with hands-on testing and automation internships, helps me connect reliable systems engineering with practical business needs.
