About
Engineering that respects your time.
I build practical web and mobile applications that solve real problems without unnecessary complexity. My work blends engineering, UI design, and product thinking - from Angular and Cordova apps to Node.js APIs, ColdFusion systems, and AI-powered workflows using tools like OpenAI and Claude.
With over 2 decades of experience across web and mobile development, I focus on cross-platform apps with reliable, maintainable systems and UI that just works. I treat AI as a tool for better workflows, not gimmicks.

Approach
How I build.
I care about products that feel obvious, fast, and trustworthy. Whether it's a simple password generator, or a business workflow tool, the goal is the same. Remove friction, make the useful path easy as possible.
01
Understand the workflow
Before writing a line of code, understand how people will actually use the product. What's the real job to be done?
02
Design the simplest useful version
The first version should do one thing well. Simplicity isn't laziness, it's the hardest part of product design.
03
Build fast, reliable interfaces
Clean code, performant UI, tested flows. The polish isn't decoration, it builds trust with every interaction.
04
Iterate with clarity
Ship, observe, improve. Good software isn't finished - it evolves as users and needs change.
