About Jakub

I spent 18 years operating IT infrastructure — networks, servers, virtualization, security — at companies like Ceske Radiokomunikace, Alza, and currently a banking IT provider in Prague. Senior sysadmin, then team lead. I know how systems break in production, not just in docs.

Last year, that experience collided with AI. Today I build production AI agents that take over real employee work in small and mid-sized companies: content scheduling, customer communication, ops monitoring. Each agent owns a defined responsibility, connects to the client's existing tools, and delivers measurable results.

My main project is MujAsistent — a multi-tenant AI agent platform on Kubernetes (k3s on Hetzner): per-customer isolation, OpenBao secret management, observability stack, automated end-to-end onboarding, Meta App Review approved, GDPR-compliant. Built solo in ~3 months.

I also deliver web projects end-to-end: a recent client got a static site (Astro + TypeScript), email infrastructure with deliverability fix (rspamd 9.46 to 0.36), GA4 with Consent Mode v2, and full handoff documentation — agency-quality work at fixed-cost solo delivery.

Available for short, fixed-scope engagements: AI audits, automation builds, web projects, infrastructure consulting. Remote-only. English: written and async fluent, calls work better short with translator help.

Not a 10x engineer. Just a senior systems guy who uses AI to deliver more, faster, and to translate it to non-technical clients.
