ABOUT.TXT / A LONGER INTRODUCTION
A few connected worlds.
The career is part of the story.
So are the people, the workshop, and the time outside.

01 / SYSTEMS
An engineer who kept widening the lens
I'm Matija Turk, based in Varaždin, Croatia. My career has moved through networks, telecom products, running companies, mobile-core architecture, and AI developer tools. The titles changed as the scope grew, but I kept wanting to understand the system underneath them.
I started close to the machinery: Linux, IP networks, voice services, and the practical business of keeping an operator's services working. At Novi-Net I led voice services and later became CTO. SIP, interconnections, WiFi, WiMAX, cable, and service rollout gave me a grounding in systems that people actually depend on.
That background still shapes how I work. I want to know where state lives, what happens when a dependency fails, and who will own the result after the interesting part of the project is over. I enjoy moving between the big picture and a very specific technical problem when the detail changes the decision.

02 / BUILDING COMPANIES
The product also has to survive the business
I co-founded and led OVIS from 2016 to 2022. We built our own telecom BSS/OSS products: billing, provisioning, monitoring, and the workflows behind an operator's services. Consulting and systems integration sat alongside that product work.
Running a company means that architecture, customer requirements, staffing, partnerships, and cash flow eventually meet in the same room. I also ran or helped manage smaller ventures, including Clino, AVIS, and Actum Media. They added different kinds of operational problems to the technical ones.
As Group COO at K3 Telecom from 2017 to 2022, I worked across markets, technical operations, architecture, and service delivery. I stayed involved in network design and difficult escalations. Those overlapping chapters taught me to consider the people, commercial constraints, and ongoing effort behind a technically attractive choice.

From carrier networks to engineering agents
At Enea, from May 2022 to March 2026, I worked as a Senior Solutions Architect with international operators on 3G–5G mobile-core environments. That included AAA, policy control, subscriber-related services, BGP, integration, and troubleshooting. Much of the interesting work happened at the boundary between products and an operator's existing infrastructure.
At Augment Code, my work combined enterprise customer engineering with AI developer tooling. I helped teams build and adapt workflows on Cosmos, connect tools, and work through real developer environments and deployment constraints. I also created ARF, a coordinated multi-agent engineering system, and applied it as part of a small team responsible for the VS Code and IntelliJ extensions.
I'm interested in both sides of agentic work: how to make the system dependable, and how a human stays capable of understanding and directing it. My AI Working Framework grows out of that second question. Faster execution is useful; I also want room to think about what is being executed.

Making useful things happen in Varaždin
Since 2020, I have provided voluntary management and strategic support to UGSO Varaždin, the local association of deafblind people. My contribution includes organizational planning, financial analysis, project development, events, stakeholder engagement, and working through operational or funding questions.
This is a different setting for some familiar skills: bringing structure to an idea, understanding what is feasible, and helping an organization turn plans into something it can sustain. It also puts those skills in service of people and activities that matter in the place where I live.
The association's work includes communication support, assistance, social activities, and education with schools and other institutions. Those are the organization's activities; my role is to support its management and development. I want this part of the site to make room for that quieter work behind the visible events.

05 / KIDS & EDUCATION
Give someone a way into the subject
Community involvement started well before my management titles. From 1999 to 2003 I was a Croatian Red Cross youth counselor, helping young teams learn and prepare for activities and competitions involving first aid and humanitarian principles.
At the Faculty of Organization and Informatics, I co-founded STAK and served as president from 2005 to 2008. Student participation, events, projects, and representation were an early education in bringing people together around something they wanted to change.
My radio-club involvement connects that history with a continuing interest in practical technical education. I've explored partnerships with schools around radio, electronics, and STEM, including ways to support equipment, training, and cooperation. There is room here for stories about working with children, learning by doing, and giving curiosity something concrete to work on.

06 / ON THE AIR
What still communicates when the usual network doesn't?
I'm a licensed amateur-radio operator, callsign 9A3CQO, and involved with a Varaždin radio club. My interests range from VHF/UHF repeaters and operating while travelling to digital modes, position and telemetry systems, and packet/BBS ideas. Radio keeps the communications problem tangible: the terrain, antenna, power supply, and protocol all matter.
With Meshtastic, I've been exploring a small network built around a continuously powered house node, a mobile GPS-capable node, and a Raspberry Pi bridge. Dashboards, short-term history, BLE connectivity, and MQTT/Home Assistant integration make it a useful meeting point between radio and my other systems.
I like that this work has a physical geography. Coverage is something to investigate outside, and a network is something you can carry. The blog will collect the experiments, the useful results, and the things that did not behave as expected.

07 / HOME INFRASTRUCTURE
A house with a few extra services running
My homelab centres on Unraid and Docker, with Home Assistant, networking tools, dashboards, and self-hosted services around it. OPNsense and Grafana are part of the wider picture. I like knowing where the data goes and being able to inspect the system when it behaves strangely.
Local LLMs, Ollama, OpenWebUI, automation workflows, and GPU compute give me a place to experiment with AI while owning the runtime and its constraints. A home setup makes memory, storage, power, and maintenance costs much less abstract.
I also operate a solar-PV system and follow household production and consumption. That connects energy, measurement, and automation to everyday decisions. Sometimes the most useful outcome of a dashboard is simply understanding a pattern well enough to stop guessing.

08 / THE PHYSICAL WORKBENCH
Measure. Model. Print. Try it again.
I use Fusion 360, a Bambu Lab A1, and Bambu Studio to make and adapt functional parts. The satisfying part is usually the gap between the drawing and the object: clearances, captured hardware, fit, strength, and the moment a revision finally works.
That can mean modifying an existing mesh, designing a bracket or adapter around real hardware, or choosing a material for a particular job. PETG and TPU bring different questions from a straightforward rigid print. The useful lesson tends to arrive when the part meets the thing it was meant to fit.
The same habit follows me into DIY and mechanical work. I would rather understand why something is wrong and whether it can be repaired than treat every object as a sealed product. Not every experiment needs to become a polished project.

09 / AWAY FROM THE DESK
There is a world outside the terminal
Caravanning combines family travel with a very hands-on set of questions. Layout, towing, moisture, heating, power, and the small things that make a limited space comfortable are all part of it. I want the travel notes here to include both the practical work on the caravan and the reason to take it somewhere.
I ride a Suzuki Intruder C800/C50 and do hands-on maintenance and modifications. Motorcycling and cycling give me a different pace from work. Gardening, home projects, and coffee have their place too; I don't need every interest to justify itself as professional development.
I enjoy science fiction, especially stories with large systems, long time horizons, and consequences that unfold across a civilization. Family travel and ordinary time outside provide another kind of perspective. A useful day doesn't always end with a new file, a finished task, or a measurable improvement.

10 / HOW I WORK
Make the problem concrete
I tend to start with the outcome and work back through the constraints. I appreciate direct explanations, explicit trade-offs, and a concrete next step. If a detail changes the decision, I'm happy to go down a level and investigate it.
Across work and hobbies, my way of learning is practical: run it, measure it, compare alternatives, and revise the model when the evidence changes. I work well with people who can explain their reasoning and change their minds without making it a ceremony.
I'm also learning to leave space between inputs. With AI making it so easy to open another thread or generate another answer, deciding what deserves attention has become part of the work itself. That is a continuing experiment, and one I want to write about here.
