Summary
🤩
Rockstar🎓
Top SchoolMarcin Tojek is a Senior Engineering Manager based in Warsaw with over a decade of hands-on software engineering experience and a recent focus on building AI-driven cloud developer workspaces. He leads a distributed, async-first team across Europe, Africa, and the US, shipping features like sub-minute prebuilds, Dev Containers, and AI integrations with OpenAI, Anthropic, and private MCP servers. Technically fluent in Go, TypeScript, Terraform and PostgreSQL, he still contributes code and infrastructure—evidenced by work on projects such as Metricbeat, Echo, and the Coder provisioning stack. His background includes scaling observability platforms at Elastic and architecting high-throughput systems at F5 and Amazon, which informs his pragmatic approach to reliability, CI/CD and developer experience. He combines roadmap ownership and people management with active RFC-driven design and hands-on prototyping, helping teams move fast without sacrificing stability. A subtle differentiator: he pairs large-scale system design with marketplace tooling experience (Coder Registry), bridging developer ergonomics and infrastructure automation.
