I work out what software should do, then get it built. I have done it for banks, oil-rig management and the aeronautics industry. These days I consult on strategy, run a few products of my own, speak in public whenever I get the chance - and I am still trying to make it on YouTube.
Two live, two in the works - things you can actually open and use, not slideware.
Your whole garage in your pocket - track every car & bike, get reminders before things break, never miss an oil change or inspection.
See Carteca →Waste-registry software that facilitates Poland's national BDO system. Lets you log waste events on time instead of reconstructing paperwork every year, and keeps waste volumes under control.
Open Recyapp →A 30-day season for a group of friends or a couple: one question a day, guesses about each other, and a constellation that grows with every round. Built once, shelved, now rebuilt properly.
A Nokia-3310-era game. You live inside a phone - when the screen goes dark, your world wakes up. The phone is dying, and you keep it alive.
I don't sit on ideas - I try them. Apps, a startup, podcasts, even a campervan and a real-estate experiment. Some are alive, some are buried, none were wasted. The only real mistake is the thing you never tried.
Four that didn't make it. Each one paid for itself in lessons.
Pooling small investments into property. Killed by regulation - taught me how hard “simple” financial products really are.
Converted a van, rented it out, then lived in it. A crash course in ops, logistics - and unit economics.
Product-analytics-as-a-service. We got it launched and working, but it never found enough traction.
One with people living after an amputation, one (Fractional Ventures) on tech in business. Both ran out of energy before they ran out of ideas.
…and there's always a next one. That's kind of the point.
Eight-plus years as a product manager and business analyst has put me on delivery teams building for Crédit Agricole, Warner Bros. Discovery, The World Bank, Moreld Capnor and Boeing.
I've also worked with Deviniti, the company behind BIELIK, Poland's open-source LLM, and helped the Neoteric team become a top AI company on Clutch.
Company and product names above are used descriptively, to identify work I contributed to. No endorsement, sponsorship or affiliation is implied.
Building my own things is half of it. The other half is helping other people build theirs - as a mentor, an organizer, and a judge.
Selected as a finalist in one of Warsaw's startup acceleration programs, pitching and validating a venture against a strong field.
Mentored and helped run a program supporting early-stage founders - from shaping ideas to getting them investment-ready.
Judged regional public-speaking contests and help run the club itself. I teach public speaking too - communication is half of product.
YOLO Driven Development was a rule before it was a channel: follow the curiosity, ship the thing, see what happens. It isn't recklessness - best case it works, worst case I learn something. There's no losing move. The channel is where that ends up, when time and energy allow.
The valuable part is doing the thing at all. Why not?
What's on the channel
Carteca, Recyapp & whatever I'm building at the time.
Short, honest advice - the "why not?" in practice.
Reviewing the software in sci-fi films & games, rated like a PM who has to ship it.
Every now and then I post something in these places as well - some more often than others.
My framework for planning & running workshops that actually go somewhere.
Blog · SubstackLonger write-ups on productivity, product discovery, workshops & habits.
Posts · LinkedInWhere I show up most often - product notes and the occasional lesson learned.
Posts · XShort, unfiltered thoughts, posted whenever the mood strikes.
Fractional product management & workshops - I jump in, sharpen the roadmap, run discovery, and ship. Lower cost than an internal hire.
