About
Full stack developer, systems architect, site reliability and DevOps engineer with over 22 years of experience.
I design, build and run software end to end: from systems and software architecture, through React and Python application code, game engines and AI-driven automation, down to the Linux servers, Docker images, Ansible playbooks and observability stack that keep a server fleet healthy in production. Over the years I have architected and operated large-scale, multi-service production platforms — dozens of services running across a dedicated server fleet.
