About02

Turning ideas into useful software people want. Building products from 0 to 1. Design, engineering, AI.

I work at the intersection of AI, software, and product. I like taking ideas from zero to launch, building the underlying systems, and iterating quickly until the product is useful, scalable, and real.

My background spans full-stack development, data systems, and startup execution, with a focus on useful software, fast iteration, and real-world impact.
