About Maëva

Are you wasting time with crashing Excel files, repetitive manual entries, or scattered tracking across multiple tools?

🎯 I design Excel and Google Sheets tools that simplify your daily tasks: automating your processes, centralizing your data, and creating clear dashboards to aid your decision-making.

I support micro-enterprises, SMEs, and large corporations in structuring their commercial and operational data, enabling faster and more confident strategic decision-making.

Thanks to my background in marketing and UX, I prioritize a user-oriented approach: accessibility, usability, and clarity of each file are as important to me as its technical performance.

Looking forward to working with you soon!

Cheffe de projet Back Office - AFIMES

Reviewed on 5/27/2026

I provided a project brief and a dataset. Maëva quickly understood my need and identified the information in the provided elements. She created a first summary in a clear document. We then refined some elements together via video call. Then, she worked autonomously and delivered quality work, with understandable deliverables as requested, one for users, another for a technician, with the expected high-performing tool. I recommend Maëva and will use her for future projects.
