By day, I architect enterprise systems, focusing on scalability and performance. By night, I transition into a full-stack builder, breathing life into independent products.
I believe in architecture that lasts. My approach combines technical rigor with a deep appreciation for refined user experiences.
“Done is better than perfect, but perfect is just... done right.”

Selected Technologies
A selection of things I’ve built to solve real problems or explore new ideas. I use each project to learn, experiment and build with purpose.
