Senior backend JVM engineer scaling resilient microservices with Java/Kotlin, Kafka, and end-to-end product ownership.
ColombiaWhat I'm looking for
I’m a Senior JVM backend engineer with 5 years of experience designing and scaling resilient microservices end-to-end. I build high-performance solutions with Java and Kotlin, using Spring Boot to deliver maintainable, production-ready systems.
I’m strongest in API and architecture decisions—designing RESTful APIs, applying Hexagonal Architecture, and practicing TDD with JUnit and Mockito. I also turn complex integrations into reliable services, including migrating monoliths to AWS and Docker with robust CI/CD pipelines.
Beyond traditional backend work, I engineer event-driven integrations with Apache Kafka to improve cross-service communication for mission-critical systems. I continuously incorporate emerging AI technologies into my development lifecycle by integrating agentic AI tools and LLMs to accelerate investigation and strengthen workflows.
