Our experience at ERESfacility, and mine personally as managing director, with Norbert has been entirely positive. Highly professional approach, responsible and accommodating when meeting agreed deadlines. The price for his work was very acceptable for our company. Our ERESfacility portal gives our clients a perfect 24/7 overview of the outsourced facility-management services we provide. It positions us in an entirely different place relative to the competition. Having seen similar portals, I can say ours is unique. I warmly recommend the programming services provided by Norbert Kovalčín.
Dr. Ján PavlisManaging Director · ERESfacility s.r.o.
He immediately grasped my vision and offered expert advice that pushed the result to a higher level. The overall experience was outstanding. I recommend his services without reservation.

What started as an app for AI postcard analysis grew into an all-in-one platform that helps us build our brand. I’m glad I chose Norbert. He turned a basic idea into a masterpiece.

Four shapes. One operator.

Every engagement starts with a free 30-minute call. We work out whether I am the right fit, frame the problem, and sketch a rough direction. If we go further, you get a scoped proposal with a fixed price before any build contract. No obligation, no lock-in.

Pick
a week.
I'll have it live
the one after.
