CEO, Hedgehog

Fonseca has been an exceptional designer to work with. He combines strong visual intuition with a clear understanding of product goals, which consistently results in designs that are not only visually striking but also practical and user-focused. What stands out most is his ability to translate abstract ideas and rough direction into clean, well-thought-out design systems. He works fast without sacrificing quality, communicates clearly, and iterates thoughtfully based on feedback.

Founder, Transparent Space

Fonseca is my go-to designer for everything. I explain it once, and he comes back with something insanely premium. Zero back-and-forth, always top-tier.

Founder, Agent Arena

Fonseca is a hardworking guy and I decided to hire him for AI Agent Arena because of his outstanding skills on UX/UI and also his strong communication skills which led to the success of v1 for AI Agent Arena.

Head of Design, Picnic

Working with Fonseca was a great experience. He took our brand positioning and translated it into a cohesive visual identity system, defining clear standards and templates that made it so much easier to create social media content and apply our brand consistently across different touchpoints. His ability to understand not just what we needed, but why we needed it, made all the difference. Highly recommended.
