about me

I'm a Computer Engineering graduate from TED University (2022) who turned a passion for technology into a thriving career in backend development. My journey began with mastering Python and Java, and evolved into building cloud-native solutions on AWS and Azure.

Most recently at Goctur. I built scalable backend systems andcloud-native applications using Java, Spring Boot, Azure Services, MongoDB, and Apache Airflow. My previous role at Neurocess Limited sharpened my skills in Python development, AWS cloud services, React framework, Docker containerization, and NoSQL databases, giving me a solid foundation for building scalable applications.

What drives me? Solving complex problems with elegant code. I love architecting solutions that not only work flawlessly but also scale efficiently. Whether it's optimizing database queries, designing RESTful APIs, or automating workflows, I'm always pushing the boundaries of what's possible in backend development.
