Senior🎓
Top SchoolOrhan Onar is a Senior Software Engineer based in Kadıköy, Istanbul with eight years of hands-on experience building backend-first, enterprise-grade systems. He has led end-to-end development and architecture decisions—from founding a back-office app using Java Spring Boot, PostgreSQL, MongoDB, Redis, and Kafka to contributing core platform work on a no-code/low-code framework at Turkcell. Currently focused on treasury analytics, he combines Java Spring and React expertise while driving a microservices transformation to improve scalability and operational resilience. Orhan is comfortable across stacks and languages (including C# .NET and JavaScript), with a track record of implementing robust CI/CD, testing, and observability practices. He pairs practical engineering with formal study (MSc in Information Technologies) and an eye for system-level design that reduces technical debt. Despite limited public GitHub activity noted, his career shows repeated ownership of complex, production-critical systems.
