For twelve years I built online shops for other people. Now I am building my own.

01Where I came from

Twelve years of PHP and Laravel backend

I started in 2013 as an intern. I worked my way from junior to senior at a single software house, and for the last few years I ran the backend for online pharmacies and drugstores. Real traffic, real money, and integrations that have to keep working at night.

Among other things I built two accounting systems, together with feeding document data straight into the warehouse.

After hours, across those twelve years, a great many websites came out — from simple one-pagers through complex software, currency-exchange integrations and blogs built for search, to plugins written to order. Plus advisory work, consulting and sharing what I know.

02What I am building now

My own e-commerce system

Everything I learned across twelve years on other people’s shops is going into a platform of my own — built from the ground up, on my terms.

Alongside it I am developing a résumé builder: a tool where the live preview equals the finished file, because both come out of the same engine.

There is also an AI-assisted investing tool in progress — an analytical layer over market data, which I am building first and foremost for myself.

Away from code I run BajeczkaTV, a channel of bedtime stories for children where the whole pipeline is automated, and a lo-fi music brand built on AI-generated tracks.

03AI and automation

More than one mechanism at a time

I work with AI agents and automation — not as a curiosity, but as a tool that genuinely changes how much one person can build and maintain.

I am going deep on it and bringing it into daily work: wherever something repeats, a machine should be doing it.

04Where I am headed

Senior developer, not code alone

Engineering stays my foundation, but I am open to roles wider than writing code — running projects, rollouts, working closer to the product and to people.

AI now does many things at once, and that changes what this job means. I want to find out how far I can take it.
