I design and run infrastructure that stays up: scalable, stable, available and secure.
Over 6 years running Linux systems and multi-cloud infrastructure in production, with containers, infrastructure as code, CI/CD and cybersecurity, and managing projects and technical teams end to end. Self-taught, results-driven and focused on solving problems.
