Mateusz Kubiak

I look for solutions to concrete problems — through research, code, networking and automation.

I study Computer Science at Lodz University of Technology, after graduating from a technical secondary school in IT. I enjoy projects that make someone's work or daily life easier most: a registration system handling nearly 2,000 people every year, Zigbee / Wi-Fi devices integrated with Home Assistant, a home network designed from the cabling up to VLANs.

Currently Experimenting with upgrading my home for Home Assistant integration — the automations are meant to add comfort and genuinely cut some costs, e.g. heating in winter.

PPLv2 — registration system for pilgrimage participants

Problem

Registration for the Łódź Walking Pilgrimage: nearly 2,000 pilgrims every year and around 60 staff members with different responsibilities.

A web application for registering participants, built for the Łódź Walking Pilgrimage but designed to be general-purpose — ready to serve other pilgrimages and to be extended further. Staff work in a role-based system where each role can access only the features it needs. The system processes Polish national ID numbers (PESEL), so sensitive data is encrypted at field level and retention periods follow GDPR-compliant rules.

My role
I've been developing this project from requirements gathering to deployment. I wrote the code together with AI tools — deliberately, to learn application architecture, new languages and a proper workflow on a real project. I learned security along the way: I chose solutions based on my own research to protect participants' data as well as possible.

Homelab and smart home

Problem

A home that runs more comfortably and cheaply, and infrastructure where I can safely test my own ideas.

Home infrastructure I keep developing: a virtualization server, a network segmented into VLANs, remote access via Tailscale / Twingate, and device integration with Home Assistant. Automations add comfort — e.g. locally controlled lighting with no dependency on the manufacturer's cloud.

My role
Every dependency and idea tested by me — from cabling and hardware to configuration and automations.

How I work

The problem matters more than the technology

I get the most satisfaction from projects that solve a concrete problem or improve a workflow — so that something runs more smoothly and the time saved can go towards something more valuable.

Criticism is information

I value specific criticism because it's the fastest way to find the core of a problem. For the same reason, I enjoy discussions that broaden my perspective.

A team of different people

I do well in dynamic team projects and in organizing events. I learn the most from people who think differently than I do.

AI as a tool

I deliberately use AI tools for prototyping and learning, but I make a point of understanding and verifying every change. This lets me focus more on architecture and infrastructure while exploring new solutions, approaches and technologies.
