“Maty designed the UI/UX for our PlusKotas mobile app, and working with him was a great experience from start to finish. He delivered a clean, modern interface in both light and dark mode, communicated clearly, welcomed feedback, and collaborated seamlessly throughout the project. His designs were thoughtful, developer-friendly, and helped us deliver a product our client was genuinely excited about. I highly recommend Maty to anyone looking for a talented and reliable product designer.”
LUIS RIVERA
AVANTE-LOGIC FOUNDER
“Maty is a rockstar. I came to him with a need for someone who could get up to speed quickly, and think about solutions in a holistic, scalable way. He delivered in every possible way I could’ve imagined. I highly recommend working with him.”
MADISON GREEN
FOUNDER OF KEISH STUDIO
“Maty was very good to work with, continuously delivered high-quality work and went above and beyond for us to deliver a dark-mode and liquid glass version of the app that was not part of the original spec. He has a good grasp of industry trends and best practices and helped us to create a very good app that is the cornerstone of our business.”

What working together looks like.

Intro call

30 minutes on the problem, scope and constraints. You leave with a written scope and a fixed price.

GOOGLE MEET

Audit and research

Your existing product, your users, and whatever system is already there. You get the findings, not just the conclusions.

FIGMA + FIGJAM

Design

Screens and the system underneath them, reviewed with you as they happen, not revealed at the end.

FIGMA

FRAMER

CLAUDE

Code-ready handoff

Tokens, components and documentation your engineers can build straight from, not a spec to translate.

CURSOR

CLAUDE CODE

GITHUB

After handoff

Support while it gets built, because a system nobody can implement is not finished.

SLACK
