@furkanerenoglu

Experienced backend developer specializing in scalable Python and Java web applications.

I am a backend developer with 3+ years of hands-on experience building scalable web applications using Python (Django, FastAPI) and Java (Spring Boot). I have designed microservices, optimized databases, integrated payment systems, and deployed containerized services on AWS and Docker, focusing on clean, maintainable code and measurable performance improvements.

My work spans tourism platforms, payment APIs, and educational software where I improved test coverage, implemented real-time features, and delivered well-documented RESTful APIs. I collaborate effectively in Agile teams, mentor peers, and continuously apply best practices in architecture, security, and CI/CD to drive reliable production systems.
