Summary
🤩
RockstarRoger Duran is an embedded software engineer with 17 years of experience building reliable, production-grade systems and a track record of introducing Rust into embedded products. Based in Cardiff, he blends deep Linux expertise (since 2005) with hands-on work in Python async stacks, microservices, CI/CD and device fleet management for EV charging and embedded controllers. He co-founded a product-focused engineering cooperative where he led CI/CD, offline-first POS and workflow engine development, and earlier delivered large virtualization and migration projects that cut costs and improved security. An active open-source contributor, Roger has made notable enhancements to the Qtile tiling window manager—adding dynamic tagging and robust floating/fullscreen handling—that reflect his full-stack problem solving. He excels at defining pragmatic architectures and contracts between local services and cloud APIs to scale constrained devices, and is comfortable shipping across firmware, backend and operational tooling. Uncommonly for embedded engineers, he pairs systems-level thinking with a passion for improving developer experience via changelogs, canary deployments and strict service contracts.
