Back to original languageAbout Helton
Manager, B2B consultant, e-merchant — in every role of my career, I have driven with data without having the title. Today, I am training as a Data Analyst (RNCP level 6, diploma December 2026), and I am putting this dual expertise to work for your projects.
What sets me apart: 10 years at the crossroads of commerce, management, and analytics. I have managed advertising budgets by optimizing ROAS, built weekly dashboards for teams of 8 people, and tracked B2B sales cycles using real data. This is not theory — this is what I have concretely done.
Assignments: data cleaning and structuring, exploratory analysis, SQL queries on business databases, dashboard creation, reporting. I work remotely, I deliver cleanly, I communicate clearly
