Rockstar🎓
Top SchoolHasan Turken is a Founding Engineer and Principal Software Engineer with 11 years of experience specializing in Go, Kubernetes, and Crossplane, currently based in Istanbul. He has driven enterprise containerization and SaaS automation through custom Kubernetes controllers and platform work at Upbound and early-stage engineering at Limrun. A certified CKA and CKS, Hasan blends deep distributed-systems design with hands-on DevOps practices—Helm, Bash, CI/CD and provider integrations—evidenced by contributions to Crossplane core and multiple Crossplane AWS provider projects. His background in real‑time embedded systems and DSP at Aselsan gives him an unusual low‑level performance and concurrency perspective that informs his cloud-native architecture decisions. He regularly improves developer experience—adding e2e workflows, Makefile tweaks, quickstarts and partner Helm chart polish—to make complex infra consumable. Hasan balances production-grade reliability with pragmatic automation, making him a go-to engineer for platformizing enterprise products.
