What I'm looking for

I’m looking for a backend role where I can own Java/Spring Boot services, build reliable APIs with Elasticsearch and Kafka, and use AWS observability to improve reliability in an Agile team.

I’m a Java backend developer with 3+ years of experience designing and developing scalable web applications using Spring Boot and Grails. I build RESTful APIs, integrate Elasticsearch, and optimize databases like MySQL and Redis, with code quality supported by reliable JUnit unit tests.

I automate workflows with AWS Lambda and strengthen production visibility using AWS CloudWatch and Kibana. I conduct root cause analysis (RCA) and deliver actionable incident reports, and I implement secure authentication using Keycloak IAM.

In Agile teams, I collaborate through sprint planning, reviews, and retrospectives. From upgrading Redis architecture for fault tolerance to delivering analytics dashboards and implementing API rate limiting with Bucket4j, I focus on dependable systems, measurable performance, and clear stakeholder communication.
