From idea to operations. One accountable partner, predictable pricing.
I build websites, business systems and the digital backbone behind them — and then I run them too. From idea to operations you work with one accountable partner at predictable pricing: no need to coordinate a developer, an ops person and a consultant.
Four pillars, one accountable partner.
You don't need to coordinate a separate developer, ops person and consultant — the whole technology stack runs through one hand.

What I build for clients, I first try on my own products.
I design, build and operate three systems of my own — with the same method I would use for you.
MesterKontroll
Verified professionals, digital contracts and photo-proven completion — no disputes afterwards.
MűhelyKontroll
Work orders, parts and appointments in one system, so the garage stops running on paper.
SiteKontroll
A website builder for small businesses: from a ready template to your own domain, no coding, with built-in search optimisation.

This is the professional background behind every project.

What I build, I use myself

Web development (corporate sites, client portals, landing pages), custom software (ERP, CRM, booking systems), cloud and infrastructure consulting (Microsoft 365, Azure, virtualization, networking), and long-term operations and support.
Both - closing a project does not end the relationship. I run my own products (MesterKontroll, MűhelyKontroll, SiteKontroll) live myself, with the same methodology I apply to client projects.
.NET, C#, Blazor, TypeScript, React and PHP on the development side; Windows Server, Azure and Microsoft 365 on infrastructure; PostgreSQL, MySQL and MSSQL for data storage.
With a free 30-minute consultation to discuss your business goals and current setup - that feeds the Discover → Architect → Design → Develop → Launch → Operate → Support lifecycle.
Both - from a single landing page to a full custom system, applying the same enterprise mindset (security, scalability, documentation) at every size.
