What I'm looking for

I’m looking to build and scale Java microservices with Kafka, AWS, and strong CI/CD, while contributing as a Team Lead—focusing on maintainability, performance, and mentoring to ship reliable releases.

I’m a Senior Java Backend Engineer and Team Lead with 8+ years of experience delivering scalable backend solutions using Java 17, Spring Boot, and event-driven systems with Apache Kafka. I’ve built and optimized data crawling and scraping services, including multi-platform downloading using multithreading and efficient storage in ClickHouse for fast historical analysis.

I lead teams through code reviews, mentoring, sprint planning, and feature delivery, while also architecting backend improvements for scalability, maintainability, and high performance. Across platforms like health insurance and enterprise applications, I’ve resolved complex production issues (including Kafka processing bottlenecks), implemented microservices with CI/CD (GitLab/Jenkins), and supported reliable releases through strong technical documentation and cross-functional collaboration.
