You work directly with me — delivering results backed by years of experience and intuition
Oskar Mieta is the Founder, Designer & Developer behind Desses. Framer Partner & Pro Expert. Winner of the DCT Award for UX Design 2026 and the Framer Agents Hackathon 2026. Creative Talent Award finalist 2025, and named in Financial Times TNW's T750 2025 and T500 2024
Desses started long before it had a name. Back in 2018, I was already working with companies across different countries, figuring things out as I went. What began as curiosity for design and building quickly sharpened into something more specific: a focus on clarity, structure, and making things actually work.
Over the years, the same pattern kept showing up. Great ideas held back by messy execution, unclear UX, or websites that look good but don't perform.
That shaped the way I work. Impact first. Not just how something looks, but what it actually does. Whether it guides users, removes friction, and moves the business forward.
Desses exists to close that gap. I combine UX design, Framer development, and an AI layer that connects them, all in one flow. No handoffs, no relay race between disciplines, no idea lost in translation between design and build. Everything is intentional, built with care, and made to last.
Communication plays a big role in that. Clear and no unnecessary back-and-forth.
I care about the small things, even the ones most people won't notice, because that's where the difference is made. With a full-stack approach across design, development, and AI, what gets designed is exactly what gets built. And it actually works in practice.

Three principles, each with the test that proves it. If any of them reads like the opposite of how your last project ran, that's not an accident, that's the pitch.

You work with one person from the first call to launch day, and nothing you say gets lost passing through a team you never meet
You talk to the person doing the work. No account manager passing your feedback to a team you never meet, no version of the brief that got lost somewhere between the call and production. The same person who scopes the problem builds it, and answers when you have a question at 9pm.
That changes how the whole thing moves. Decisions happen in the same head that's writing the code, so nothing leaks out in translation. Fewer meetings, faster turns, and a straight line between what you meant and what ships.

You get the hundred small details handled that you'd never think to ask for, so nothing feels off and nothing gets sent back
Most of the work is the part nobody sees. The spacing that took four tries, the empty state the flow forgot it had, the line of copy rewritten until it says the actual thing.
Those details are what a visitor senses before they can name anything. A site that's slightly off makes people hesitate without knowing why. A site that's right earns their trust before they've read a word. That gap almost always hides in the small stuff, and the small stuff is where most of the hours go.
So you won't have to send it back three times to get there. The extra hour goes in up front, instead of landing on you to catch what's missing.

What the work earns you matters as much as how it looks, and that's the honest way to measure whether it was worth it
The work has to do its job as much as you need it to. So if what you're asking for won't get you where you're going, you'll hear it before we start, while it's still cheap to change course. Better that conversation early than a clean handover that quietly misses the point.
Your users and your numbers get the same attention they'd get on my own project. What people actually do on the page, where they drop off, what the site is supposed to earn you. If a prettier version would convert worse, you'll hear that too, even when it isn't the easier thing to say. The result it brings you is the point, and that's the thing worth judging the work on.
