Freelancer profile translated to English.
Back to original languageAbout Mathis
With two years of experience at Orange in financial management and automation, I support companies in optimizing their administrative and financial processes.
My daily work: transforming time-consuming manual tasks into reliable and automated systems. Specifically, this involves automating data processing (VBA, Python, Excel), structuring and validating databases, creating automated reporting, and simplifying tools for non-technical teams.
I also implement systematic quality controls on data and document processes to facilitate their transfer and auditability.
My approach is pragmatic: I start with your real constraints to deliver operational, documented, and maintainable solutions.
SMEs, small businesses, financial or administrative departments — available to discuss.
