Seventeen years, measured in shipped work.
Counts, context, and the people who paid for the work — in their own words.
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.

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.

04 · How I work
Scope · Build · Ship · Support
Four steps, eight weeks typically. Twelve worst case — because twelve-week rewrites are how projects die.
01
Scope
One call, three sharp questions, one architecture proposal. I qualify the fit before anyone commits.
Discovery sprint (1-2 weeks) produces: problem framing + user map, stack + architecture decision, scoped roadmap with estimates, working prototype where it adds value.
02
Build
Small commits, fast feedback. Production-grade from day one — observability, backups, docs.
Milestone-based. Design + code in the same hands, so no telephone-game loss between surface and system. Staging deploys from commit 0.
03
Ship
Launch with monitoring wired, CI green, rollback plan ready. No 'we'll fix it in the next sprint.'
Vercel preview → production with DNS cutover runbook. Sentry + Vercel Analytics active before first real user touches it.
04
Support
Retainer or hand-off — your call. Documented either way, so the next person knows what they're looking at.
Retainer: reserved hours/week, priority response, quarterly roadmap reviews. Hand-off: onboarding doc + architecture diagrams + 2 weeks of overlap.

Every engagement starts with a paid Discovery Sprint — €1,500, typically 1–2 weeks. Output: problem framing, architecture decision, scoped roadmap with estimates, working prototype where it helps, and a fixed-price build proposal. The sprint fee credits toward the first invoice if we continue to build.

The Solo Studio Is the Highest-Leverage Business Form of 2026
Five years ago, a solo consultant lost almost every pitch to an agency. In 2026 the math reversed — and most agencies have not noticed yet. Here is why one person, one mind, one decision is now the operating model that out-competes a 12-person team on most projects under €80,000.
AI Chatbots for Small Business in 2026: What Actually Works
Most AI chatbot pitches promise the same thing — deploy and watch your support costs vanish. Here is the honest version, from someone who builds them: when they pay back, when they fail, and how to budget for either outcome.
How to Hire a Full-Stack Developer in 2026 (Without Getting Burned)
Most full-stack hires fail not because the developer is bad — they fail because the company hired the wrong shape of person for the actual problem. Here is how to tell the difference, what to ask, and what real EU rates look like.
