One person, one point of responsibility.
From the first conversation to deployment I run the project personally. I write the code. I make the technical decisions. When something breaks at 10 pm, I am the one who picks up the phone.
About me · Senior Fullstack Developer
One developer. From idea to deployment.
I work with B2B companies in Poland and abroad. For 8 years commercially, in production - since 2018. Most clients stay with me for ongoing care.
§ 01 How I work
What working with me looks like.
First contact is usually an e-mail or the form. I always reply personally. If the topic sounds sensible and looks like my territory, we book 30 concrete minutes about your project.
After that call you get it in writing: what I understand from your problem, the scope I propose, a concrete price and the date I can start.
Once we sign, I work in weekly sprints. Every week you get a demo (a 15-minute meet) and a concrete update on our shared channel. Everything lands in your repository from day one - the code is yours, not mine.
Most clients stay for ongoing care or a retainer after the first project.
§ 02 Rules that have proven themselves
The studio manifesto.
Written down after the tenth time I had to tell a client "no" - and it turned out better for both sides.
A concrete quote. Decision after one call.
I know what things cost. I do not drag it out - and I do not do that to you either. After the first call you know whether we are going ahead.
I speak plainly.
No "synergy", no "digital transformation", no "end-to-end solutions". I explain technical decisions so that your accountant understands them.
Client opinion
"Krystian talked less and did more. He quoted it, gave a date, delivered."
