Summary
👤
Senior🎓
Top SchoolMarek Jelen is a founder and seasoned software engineer with 16 years of experience building cloud-native platforms, developer ecosystems, and web applications from Prague. He founded FinForce and runs freelance engagements, combining hands-on engineering with product and go-to-market experience honed during seven years as a PaaS advocate and principal product marketing manager at Red Hat. His technical roots span Ruby, Java, PHP, Python and Node.js, and he has practical DevOps expertise—automating OpenShift deployments with Ansible and integrating persistent volumes and cloud droplet provisioning on GitHub. A former university lecturer and community builder (founder of the Brno Ruby Users Group), he blends teaching, public speaking and technical writing with system architecture work. Marek’s background in service science management and long track record across startups and enterprise projects means he navigates both code-level problems and strategic product decisions. He’s quietly pragmatic: equally comfortable scripting infrastructure for repeatable tests and explaining complex cloud concepts to developers.
