Headline: 25 years building enterprise software · Now embedding AI into production systems
About: I have spent twenty-five years inside one company watching technology change in cycles — from desktop to client-server, to fully web-based, and now to AI-native.

What that teaches you, mostly, is humility. Every wave looked transformational. Most were. But the ones that delivered lasting value were rarely the ones that arrived loudest. They were the ones that earned their place inside systems that already worked.

This shapes how I think about AI today. Not as a replacement for what works, but as a layer that earns its place inside systems that already serve real customers.

As Chief AI Officer at AccountTECH, I lead the company-wide adoption of AI across products, operations, and team capability. My approach favors production over pilots, integrating over rebuilding from scratch, and delivery speed over endless planning cycles.

Twenty-five years in, I still find this work interesting — and that surprises me as much as anyone.
