About Anthony

I transform scattered data and manual processes into clear dashboards and automated reports that save you hours every week and show you what decisions to make.

I am a Data Analyst / BI Consultant with over 6 years of experience helping companies extract, validate, and visualize their information to make data-driven decisions, not just intuitive ones. I have worked in banking, telecommunications, and IT, on projects involving data modeling, reporting, and business analytics.

🔹 How I help you

Interactive dashboards in Power BI and Looker Studio that your team truly understands and uses.
Reliable data modeling and KPIs, so your numbers add up and mean something.
Automation of reports you currently do manually (Python, Google Apps Script, VBA): from hours to minutes.
Integration of data from multiple sources (SQL Server, BigQuery, PL-SQL, ETL) into a single, consistent place.
Validation and cleaning of large volumes of data, eliminating errors before they reach the report.

🔹 Concrete results

Automated the consolidation of 17 monthly Excel files into a single model: what used to be manual work of hours is now updated automatically.
Power BI dashboards with multi-level drill-down for real-time project tracking.
Data architecture in BigQuery for multi-source marketing analytics, connecting campaign performance and leads.

🔹 How I work

Agile methodology, clear communication, and deliverables aligned with your needs. I explain the 'why' behind each technical decision, not just the 'what'.

✨ My goal: to turn your data into clear and strategic decisions, with efficient and scalable solutions.
