The person behind KD Studios

I'm Kiavash: product designer, full-stack engineer, and founder.

I began building software in 2019 out of curiosity. Over the years, that work grew into an end-to-end discipline spanning mobile applications, web platforms, custom AI integrations, and cloud infrastructure.

KD Studios was founded on a clear principle: digital products are strongest when interface design and backend architecture are built by the same hands.

Traditional agencies push projects down an assembly line of sales reps, account managers, junior designers, and external developers. The original product vision gets diluted, progress slows, and simple updates turn into costly change requests.

I operate differently. As a solo studio, I design every screen, write every line of production code, configure the deployment pipeline, and communicate with you directly. You get senior execution, rapid iteration, and zero agency overhead.
