They’re the reason clients stay for years.
Clean, tested, maintainable code. We get the details right, and we leave a codebase the next engineer can work in.
“His code is clean and concise.”
We think in systems: the interface, the data, the integrations, and how it all runs after launch. Not just how it looks.
SelfManager.ai: designed, built and operated in production by Marian.
Building software since 2010 means risks get spotted early and decisions stay practical. You don’t pay for our learning curve.

We stay responsible through delivery and after it. Many clients keep working with us for years.
“I had the pleasure of working with Marian again after six years, and I couldn’t be more pleased with the experience.”
Clear scope, honest advice, reliable communication and a documented handover. If something is a bad idea, we say so before you pay for it.
“I got constant updates, smart suggestions, and honest professional feedback.”
"I can't recommend Marian enough. He stepped in to handle a complex, custom Squarespace project that two other coders couldn't complete—and he handled it with ease."
Every project has the founder on it: not as a sales overlay, but doing the engineering.
That line is how I’ve worked from the start. It means I begin with your business goal, not with a technology I’d like to use. I recommend the scope that makes sense for where you are, and I tell you when something is a bad idea before you pay for it.
And I stay accountable after launch, which is why many clients have worked with me for years. abZ Global is the studio built around that standard.
When a project needs more hands, I lead the team, with one person responsible: me.
