Infrastructure
by profession.
A home lab
by curiosity.

I look after systems that people depend on. At home, I explore what I can build with my own hardware, open source and a little persistence. From private infrastructure to a local AI agent.

01 / After hours

Projects I actually
use every day.

I build services for myself and my family, measure how they behave and improve what falls short in everyday use. Running another container is only the beginning.

01 — HOME AIRunning · evolving

An assistant connected
to my environment.

I connected a local language model to web search, Windows diagnostics, SSH, email and calendar tools. Open WebUI is the conversational interface; my own PC handles inference.

The interesting part was getting from “I don't have access” to a real tool call, with an actual result that I can verify.

  3. Control over actionsI approve email drafts before sending.

02 — NETWORK & SERVICESRunning

My own infrastructure.
Accessible from my phone.

MikroTik with WireGuard, Synology with Docker and a shared Homepage dashboard. Availability monitoring, connection speed history, a password vault and my own music library.

03 — OBSERVABILITYRunning

Visibility into my network
and connected devices.

600 / 100

My connection speed in Mbps, checked through measurements. Uptime Kuma tracks availability, MySpeed records throughput and Homepage brings the results together. I can investigate with data when the network feels slow.

02 / My approach

I like understanding
what runs underneath.

My professional work centres on Linux infrastructure, reliability and automation. I care about the whole chain: networking and storage, configuration, logs and the experience of the person using the system.

After hours, that same curiosity takes me into self-hosting, local AI, photography and 3D printing. I like testing an idea on my own hardware, understanding its limits and then building on it.

My home lab should make everyday life easier. It also gives me room to take an idea from a first script to a working service.

03 / Professional background

Linux at the core.
Responsibility for
the whole system.

My background spans large private cloud environments, identity infrastructure, third-line support and operational automation. I combine day-to-day operations with root cause analysis.

04 / Next experiments

A home lab is
never quite finished.

These are the next items on my development list. I introduce them in stages, starting with a small use case I can verify.

PLANNED / KNOWLEDGE & VOICE

Closer to everyday life

RAG over my own documents, answers with source references, spoken Polish and convenient access for family members from their phones.

PLANNED / MEDIA & 3D

From images to stories

Consistent characters across illustrations, additional ComfyUI workflows and experiments with video, music and 3D model generation.

PLANNED / AUTOMATION

Less manual operation

Waking the PC on demand, improving GPU resource management and connecting more devices. Independent backups and restore testing for essential data are also on my list.
