About Tonio

Business Analyst Data / techno-functional, I help business, IT, and data teams secure their transformation projects around data: ERP, e-commerce, BI, CRM, data integration, and reporting... now boosted by AI.

My role: clarify needs, formalize business rules, frame flows, ensure data reliability, and secure testing.

🔎 Problems I often address:
- Data scattered across ERP, CRM, e-commerce, finance, or supply chain systems;
- Critical Excel files and manual data entry;
- Misaligned indicators between departments;
- Unstable or poorly documented data flows;
- Complex testing due to lack of formalized rules;
- Difficulties scaling in a multi-subsidiary / international context.

🛠️ What I bring:
- Functional scoping and workshop facilitation;
- Data mapping and transformation rules;
- Functional and techno-functional specifications;
- Business / IT / Data coordination;
- Functional testing, UAT, and post-go-live support;
- Structuring of reporting and steering indicators.

📊 Recent impacts:
- Automation of an order integration process: -70% processing time;
- Estimated saving of 1 to 2 FTE on data entry tasks;
- Implementation of a central multi-subsidiary middleware;
- Improved supply chain management and reduced supplier delays;
- Adoption of dashboards by over 90% of business teams.
