Senior🎓
Top SchoolSiarhei Dounar is a DevSecOps SRE based in Dubai with a long technical career transitioning from system administration into cloud-native reliability and security. He brings deep hands-on experience building and migrating large-scale AWS and Alibaba Cloud infrastructures, Terraform/OpenTofu automation, Helm and EKS migrations, and production Postgres operations. Known for establishing CI/CD best practices, cost-optimized cloud architectures and observability stacks, he combines developer support with strong security controls across the delivery lifecycle. His background spans consumer tech and marketplace platforms including Yandex, Bumble and Zendrop, giving him experience across both massive-scale services and fast-moving startups. A physicist by training, he pairs analytical rigor from radiophysics with pragmatic SRE engineering, often driving migrations and infrastructure-as-code transitions end-to-end. Despite an 8-year formal DevSecOps tenure listed, his operational roots date back to early 2000s telecom and billing systems, which informs a reliability-first mindset.
