What I'm looking for

I’m looking for a Java backend role where I can own Spring Boot services and Kafka integrations, build clean architectures, and improve performance and reliability through CI/CD, monitoring, and incident-driven iteration.

I’m a Java Backend Developer focused on building Spring Boot REST APIs and Kafka-based integrations with an emphasis on clean architecture, validation, and reliable error handling. I work with Java 17/21 and design services that are both maintainable and performance-aware.

In my self-employed work, I delivered a multi-module Java backend with 100+ REST endpoints and a layered structure (domain, use case, persistence, web). I engineered Kafka workflows across 10–15 topics and separated synchronous REST boundaries from asynchronous integration flows.

I’ve also owned delivery and reliability end-to-end: I containerize with Docker Compose, use Nginx as a reverse proxy/gateway, and standardize database changes with Liquibase. I improved a deployment cycle from 20 minutes to 5 minutes, and stabilized runtime behavior by applying Nginx rate/connection limits and container resource limits—reducing load spikes from 430% CPU to about 0.2–1% steady state.

Previously, as a Full-Stack QA Engineer on a backend track, I strengthened quality gates by integrating Java API testing with REST Assured into CI/CD in TeamCity. I reduced incident triage from 1 day to 2 hours and cut regression time per feature from 12 hours to 4 hours, then supported backend release readiness with better automation and traceability.
