Bilal Köse
Computer Engineer
Computer engineer with 10+ years of hands-on experience. My day-to-day work is software engineering in the .NET ecosystem — scalable microservices, cloud-native APIs, and production-grade backend platforms — but my engineering background is broader: computer networks, Linux systems, security, and infrastructure from on-prem to cloud. I care deeply about clean architecture, maintainable code, and engineering excellence, and I bring the same rigor whether the problem is a distributed system, a Kubernetes cluster, or a mission-critical ERP.
