Background
With nearly two decades in the software industry, I've spent the majority of my career building enterprise-grade platforms in the Microsoft ecosystem. My journey started at MRMLS (now CRMLS) in 2007, where I grew from Systems Developer to Director of Engineering over 19 years.
I have a passion for systems design and architecture. I believe the best engineers stay hands-on while leading — and that's the approach I bring to every team I join.
AI & Innovation
These days, I'm particularly interested in AI-assisted development workflows. I was an early adopter of tools like GitHub Copilot, Claude Code, and custom AI agents — and I evangelize their use to accelerate delivery without sacrificing code quality.
