Hi, I'm
Kiavash.
I build things
that ship.

Solo designer & full-stack engineer based in Denmark. I take software from initial concept to live production app — mobile, web SaaS, and AI infrastructure — with total ownership. No agency bloat.

The person behind KD Studios

I'm Kiavash — designer, engineer, and solo founder.

I've been building digital products since 2019 — first out of raw curiosity, then out of conviction. What started as learning to code turned into a full-stack discipline that spans native mobile apps, web platforms, AI pipelines, and cloud infrastructure.

I started KD Studios with a simple conviction: the best digital products are built when design and engineering happen in the exact same head.

When you work with a traditional agency, your project gets passed down a long chain — from a salesperson to an account manager, down to a junior designer, and off to a developer. By the time it ships, the original vision is diluted, communication lags by days, and every small adjustment requires a change order.

KD Studios is intentionally small. I personally design every interface, write every line of code, architect the cloud setup, and answer your messages directly. You get high-craft design, production-grade engineering, and zero agency friction.
