I map how your company really works, pick the places where AI pays off, build it myself and keep it running. With commercial models, or open-source ones on your own servers when the data can’t leave the building.

Free consultation. I normally bill by the hour, but the first 30 minutes are on me.
My classes come straight from systems that are live today.
Postgraduate programme in critical infrastructure management, under the patronage of the Government Centre for Security. 2026
For my class I built a live platform and ran a two-day GenAI crisis exercise. A model drafted the replies, and I had 90 seconds to veto each one.
AI in finance and accounting, Master’s studies. 2026
From data quality and classic machine learning to document automation, chatbots and the AI Act. Each student ends by defending a prototype of their own.
Before I built AI with my own hands, I ran product and sat on two boards. Budget, risk, payback, what happens when it breaks: I asked those questions for years. Now I plan for them from day one.
Chief Product Officer, then board member
The partner programme I built in more than 50 countries grew annual recurring revenue from $250K to $1.2M. With our CTO I rebuilt the core product, and we built custom solutions for McDonald’s, Ericsson, Orange and Marriott.
Co-founder and board member
A football app taken from zero to a commercial contract with PZPN, the Polish Football Association. In equity crowdfunding we raised about 1M PLN from more than 50 investors, the second-largest such round in Poland in 2022.
Co-founder
Two platforms for transport companies: a freight exchange and a transport management system. Both are live, and I still write most of the code.
Owner of Lynxon, AI consultant to JP Weber since 2023
My own company. Since 2023 I’ve been building AI for JP Weber and its clients: knowledge assistants, analysis of call-centre conversations, forecasting for solar farms.
It’s the first rule of diving, and it’s how I run AI projects. The planning happens on the surface, and I stay for the whole dive, including the slow climb back up.
I sit with the people who do the work and write down how it really flows. It’s rarely what the org chart says.
Together we pick the two or three places where AI pays off, and a model that suits the task and your rules for data.
I build it myself. A person approves what matters, costs have a ceiling, and there’s a plan B for the day a model misbehaves.
Monitoring, fixes and training your people. It’s the safety stop: nobody likes paying for it, everybody needs it.
It just runs. You get on with your job, and I’m a message away.
A few of the systems I built and still run. Since 2025 I’ve shipped more than 35 projects, and plenty of them are internal tools or client work I can only show you on a call.

Transport management for hauliers and forwarders
Orders, fleet, drivers and invoicing in one system, in eight languages, with Poland’s KSeF e-invoicing live in production. When a transport order arrives as a PDF or a photo, AI reads it and fills in the order. A person checks it before it’s saved.
Reading one order costs less than a twentieth of a cent.

GLM 5.3 Flash through OpenRouter$0.00045 per documentMove the lens over the screen to see what’s underneath.
A free freight exchange for carriers and forwarders across Europe.
The AI part. Forwarders e-mail their loads in any language. Gemini turns each e-mail into a structured listing, placed on the map.
Visit eTrans24: etrans24.comConsumer bankruptcy applications, prepared online.
The AI part. An OpenAI model drafts the official court form from the client’s answers. An automated test checks every release, and personal data never goes into the prompt.
Visit ZgłośUpadłość: zglosupadlosc.plCase files, statutory deadlines and 18 ready-made documents for bankruptcy trustees.
The AI part. Claude reads the court ruling and fills in the case, marking how sure it is about every field.
Visit Restrio: restrio.plWebsite and shop for a symphonic orchestra that plays the music of Heroes of Might and Magic.
The AI part. The concert list updates itself every morning. If one model is down the next takes over: Groq, then Claude, then Llama.
Visit Heroes Orchestra: heroesorchestra.comThe platform of divers looking after a flooded quarry lake in Kraków.
The AI part. A two-hour City Hall meeting became a bilingual public record on the same evening, every claim linked to its timestamp in the recording.

I’m a technical diver and an SDI instructor, and I dive sidemount: two independent tanks.
I build AI the same way. Every system I ship has a plan B for the day a model misbehaves, and notes your team can follow while I’m underwater.
I teach Solo Diver and Sidemount at DiveBay, my small dive school in Warsaw, and I look after the platform for Podwodny Zakrzówek.
Tell me how it works today. In 30 minutes I’ll tell you honestly whether AI helps, what it would cost and how long it would take. The call is free and you’re not committing to anything.
