Rockstar🎓
Top SchoolGökhan Özeloğlu is a pragmatic software engineer with eight years of hands-on experience building and hardening payment infrastructure at scale, currently shaping Getir’s payment stack from Java Spring Boot services to Grafana and OpenTelemetry observability. He has a strong backend focus—implementing new payment methods, RabbitMQ consumers, Redis/Mongo token logic, and preparing multi-service blue-green deployments—while also owning on-call incident response and architecture reviews. Gökhan elevated test coverage dramatically (consumer service from <5% to >95%) and contributes to open-source Go projects, improving reliability through thorough unit and integration tests for libraries like knadh/koanf. His background includes roles at Delivery Hero and TÜBİTAK, and a Computer Engineering degree from Hacettepe University, reflecting solid institutional and startup-style experience. Notably, he combines production debugging skills (e.g., fixing refund/balance inconsistencies via MongoDB change streams) with a penchant for practical automation and monitoring migrations. Colleagues know him as an engineer who bridges deep technical fixes with clear operational improvements.
