I'm a software engineer and technical lead with 24+ years of experience building, modernizing, and shipping production software.

I spent much of my career developing mobile applications, but my work has grown to include software architecture, enterprise integrations, cloud platforms, and AI-assisted engineering.

I enjoy solving complex problems, learning new technologies, and building things that actually make it into production.

• AI-assisted development — Exploring agentic workflows, GitHub Copilot, Claude, and ways to make software engineering more effective.
• Software architecture & modernization — Making existing systems better, not necessarily rebuilding everything from scratch.
• Hands-on engineering — .NET, C#, TypeScript, Kotlin, Azure, and whatever tools make sense for the problem.
• Personal projects — Building useful applications, experimenting with ideas, and occasionally scratching my own engineering itch.

You'll find a mix of older mobile development projects, sample applications, and experiments here. Some date back to my Xamarin and native Android days, and I keep them around because they've been useful to other developers.

Most of my recent professional work and personal projects live in private repositories.

AI makes me faster. Engineering judgment, quality, and accountability are still my responsibility.
