Seventeen years in the field.Now I build the software for it.

From a hardware-store floor at fourteen to a STIHL territory today. I ship AI products, agent systems, and the software around them.

About

I know how field sales actually works — dealers, inventory, sell-through, and the relationships that decide whether any of it moves. That is not something a requirements document teaches you.

It is why the software I build tends to be right about the unglamorous parts. Every project above began as a problem I hit myself, so the edge cases showed up before the features did.

And because I run all of it end to end, nothing gets handed off and lost — the person who designed it is the person who fixes it at six in the morning.
