Available for new projects
A developer who cares about craft & impact.
I'm a full-stack developer with 6+ years of experience turning ideas into polished, production-ready products. I've shipped web apps, developer tools, and cloud infrastructure used by teams around the world.
I care deeply about clean architecture, delightful user experience, and writing code other developers actually enjoy maintaining. Outside client work, I build and run my own products under the FlazHost brand.
