AboutDesigner & developer,
Designer & developer,
from idea to launch
I'm Ajda, based in Ljubljana. I build products solo from start to finish, so nothing gets lost in translation between designer and developer.
At Popsy (Y Combinator), MooHero, and Topsi AI I learned to move fast and build things that work for real users. Same energy whether you need a site, an app, or a brand.

FAQ
Frequently Asked Questions
How much does a website cost?
It depends on scope. A simple presentation site starts at €500. More complex sites with booking or e-commerce cost more. I estimate each project after a free 30-minute call.
How long does it take?
Most sites ship in 1–2 weeks. A simple landing page can be ready in a few days. Larger projects with custom design or a mobile app take 3–4 weeks.
What technologies do you use?
Next.js, React, TypeScript, and Tailwind CSS. Fast to load, easy to maintain, ready for SEO out of the box.
Do you also offer design?
Yes. Figma UI/UX through to development and launch. You don't have to coordinate a separate designer and developer.
Is the website mobile-optimized?
Yes. Every site I ship is fully responsive and technically ready for SEO.
