50+ sprints. Ethereum to ConsenSys. The UX behind some of Web3’s most important launches.
Read the story“I’m amazed. Unbelievable. Everything was done so fast and the quality of the insights from the user validation is incredible.”
BartoszCo-founder, Research Tech“Shortest design cycle available on the market. Charlie is a master of communication, so working with him is not only very effective, but also a real pleasure.”
Szymon SypniewiczCo-founder of Ramp Network“In a mere two weeks, they took a high-level concept and turned it into a visually stunning leaderboard app that delights our users. As a small, highly technical team, we found that because they were able to own all the design, UI/UX and front-end engineering related to the project, it allowed us to concentrate on back-end and data engineering, where our strengths lie.”
MikeCo-founder, Hummingbot“We found Charlie by searching for the Ramp designer — we needed someone who actually understood fintech UX. His user testing caught what we never would have: users freezing on the first screen, not understanding why verification was needed. Insights that would have killed adoption. He delivered it all in production-ready code we could integrate directly — no Figma translation, no months of back-and-forth. His work was instrumental to securing our next round of funding.”
