What I'm looking for

I am seeking a role building scalable, microservice-based systems where I can drive backend architecture, improve observability, and deliver reliable, testable software within Agile teams.

I am a Full-Stack Developer with extensive experience designing and implementing Java Spring Boot microservices, building resilient event-driven systems, and optimizing enterprise application performance. I have a strong background in PostgreSQL, Cassandra, Elasticsearch, Redis, Kafka and message brokers such as RabbitMQ, and I consistently deliver testable, maintainable code across the full software development lifecycle.

I have contributed to cross-functional Scrum teams on cloud-based bookkeeping and healthcare platforms, led migrations of core business processes to microservices, and authored automated test suites using JUnit, Mockito, Groovy and Spock. I prioritize clean architecture, observability with Datadog/Grafana, and CI/CD practices to ensure reliable delivery and scalable production systems.
