About Me

Passionate and results-driven backend developer with 3+ years of experience building robust, scalable systems for high-traffic platforms like Bilyoner and GittiGidiyor. I specialize in Java, Spring Boot, and Python, and thrive in microservice architectures where performance and reliability are key. My toolbox includes modern infrastructure tools like Kubernetes, Kafka, Jenkins, and GitLab, as well as both SQL (Oracle, PostgreSQL, MySQL) and NoSQL (MongoDB, Redis) databases.

I enjoy solving complex engineering challenges, building clean APIs, and writing maintainable code that supports long-term product growth. Currently expanding into full-stack development, I’m always exploring new technologies and pushing myself to grow—because great software starts with curiosity and craftsmanship.
