Building with
Modern Tools
Composable when ROI is clear, monolithic when it makes sense. Strong focus on Cloudflare edge for performance and global reach.
20+ Years Building Software
Full-Stack Developer → Tech Lead → Solutions Architect → Director of Engineering. I've worn many hats and I still love the craft.
I can advise from the outside or roll up my sleeves and build with your team. Microservices when they make sense, monoliths when they don't, and edge computing to make it all fast.
