CV

Tomas Dabašinskas

Team Lead, Site Reliability. Lithuania, remote; twenty years in IT.
GitHub · LinkedIn

I lead a small DevOps and database team that keeps a multi-region AI platform running on AWS, GCP and Cloudflare. Before that I spent over a decade at a global open source software company, building and operating managed Kubernetes services. I care about boring, measurable reliability, infrastructure kept in git, and teams where no one person is the bottleneck.
