Description

Expert UX/UI for SaaS & Business Software.

I help Tech publishers and startups transition from "functional" software to an "exceptional" product that teams love to use.

I don't just "make things look good": I design fluid work tools that save your end-users time.

My approach combines ergonomic rigor with an understanding of your business challenges (reducing churn, increasing adoption).

Charles worked on the UX redesign of our platform and the result met our expectations. He quickly understood the challenges of a mass-market platform dedicated to contesting property tax, where clarity of the user journey is crucial for conversion. His work on the conversion funnel - from the homepage to the simulator - was precise and results-oriented. He identified friction points, proposed concrete and prioritized solutions, and supported us through implementation. He was very proactive throughout the mission, proactive, and always one step ahead on the topics to be addressed. Smooth communication, deadlines met, real ability to translate complex business constraints into a simple user experience. We recommend Charles without reservation and hope to work with him again on our future projects.
