What I'm looking for

I’m looking for a team that values Agile delivery, secure microservices, and measurable quality. I want to build cloud-native systems end-to-end—automation, testing, and observability included—while partnering closely with product and engineering to ship reliably.

I’m a Full Stack Java Developer who builds end-to-end solutions across SDLC—requirements to deployment—using microservices, robust REST APIs, and secure authentication. I focus on scalable, maintainable systems in fast-moving Agile teams, using Spring Boot and Spring Security (OAuth2/JWT) to protect APIs and deliver reliable integrations.

I bring strong event-driven and cloud automation experience, creating Kafka-centric pipelines and Spring Batch workflows, while provisioning resilient AWS infrastructure with Terraform and deploying on Docker/Kubernetes. I also care deeply about quality and visibility—covering automated testing (JUnit/Mockito/Selenium) and observability with Splunk/Grafana/Log4j to keep performance and reliability measurable.
