ABOUTDFIELD SYSTEMS
WHO WE ARE
I'm Dezső Mező, and I operate an independent engineering consultancy as DField Systems, part of the family-owned DField Kft.
As a freelancer, I build on 25+ years of professional experience gained across EPC, OEM, and owner/operator environments, primarily in gas turbine and combined-cycle power plants. I bring a full-lifecycle project perspective to every assignment, connecting technical details with their operational, maintenance, and commercial implications.
I work through a simple and efficient operating model from my base in Dunakeszi, Hungary. My work is defined by precision, sound engineering judgment, and personal accountability. Where it provides genuine value, I use modern AI tools to support research, analysis, and documentation; while always taking personal responsibility for every engineering decision, technical deliverable, and final outcome.
