Hi, I'm Serg 👋

DevOps / Platform Engineer · Stuttgart, Germany · serg-markovich.de

What I do

I build and operate infrastructure. Linux servers, Docker stacks, CI/CD pipelines, automation.

In 2025 I deployed a self-hosted 14-service Supabase stack on Hetzner VPS for a production healthcare platform — Kong API gateway, GoTrue auth, PostgREST, Realtime, Storage, Edge Functions, Supavisor, Caddy, Vector. Zero critical downtime migration from Supabase Cloud.

Before that: 700+ live web properties, team of 20, full server stack ownership for 8 years (2017–2025).

Currently: building self-hosted infrastructure projects, AZ-104 in progress, open to DevOps / Platform Engineer roles in Germany.
