Heinz Duyao
Say it doo YAH oh. Auf Deutsch: Du Ja Oh.
I see patterns.
I build systems around them.
Deals. Code. Life.
Same precision.

Story
Radically curious. I stay with things, turning stones until a simple path appears. That started early — taking apart whatever was in reach to understand why it worked. The drive never left. It just moved to larger things.
I started at Sun Microsystems in 2008, fresh out of HTL and military service — a junior engineer on pager duty at 2am, wrestling with tape libraries in dimly lit data centre rooms. Oracle followed: eight years moving from technical support through account management across Austria and CEE, learning how enterprise decisions are actually made. Dell Technologies showed me the infrastructure layer from the outside. At AWS I work with financial institutions across Austria and CEE, where one architectural decision ripples through a regulated industry. Seventeen years. Each place was a different system. The question underneath never changed.
The curiosity eventually started generating infrastructure. Agentic AI systems that pull context before a meeting, surface patterns across accounts, reduce the friction that burns hours. A homelab running the backend. Generative AI arrived at the right moment — a way to externalise structure at the speed it forms. That changed what I build. A well-architected system follows the same logic as a precisely timed recipe: if the system is right, the outcome is inevitable.
Outside work I cook. My meditation. I test, refine, and plate with intent. It keeps me precise and honest.
Enterprise taught me to operate at scale. Now I am compounding that into something of my own.
Thinking
Every field guards its own language. Underneath, the structures repeat. A pricing model for enterprise software and a precisely timed braise are both optimisation problems with constraints, feedback loops, and diminishing returns. Once you see that, you cannot unsee it.
I call it structural transfer — taking a framework from one domain and applying it where nobody expects it. The negotiation tactic that unlocks a stalled deal is the same tactic that fixes a flaky home automation. The debugging method that isolates a network fault finds the flaw in a recipe. The pattern is never obvious at the surface. You have to go one level deeper.
Most expertise runs vertical. The rarest skill is horizontal fluency — moving between domains without losing rigour. The interesting problems almost always sit at the boundaries. That is where I work.
Connect
I enjoy conversations with builders, operators, and anyone who gets excited about the space between disciplines. Whether you are working on something ambitious, thinking about a deal, or simply curious — I would like to hear from you.
If you are the type who looks a little deeper — you will find something. Reach out when you do.
