About Boris

Data Analyst / BI Engineer / IT Analyst consultant, graduated from EFREI Paris in Computer Science with a specialization in Big Data, with over 5 years of experience in large enterprise environments: banking, media, telecom, retail/luxury, and HR.

I work on missions with a strong technical and functional dimension, at the interface between business, data, BI, and IT teams. My role involves analyzing needs, ensuring data reliability, producing reliable indicators, and supporting users in the use of their decision-making and application tools.

My areas of intervention notably cover Business Intelligence, operational reporting, data quality, SQL analysis, KPI production, data flow reliability, BI/application support, and data incident management.

I support teams on:

BI & Reporting
Creation, maintenance, and migration of Power BI, SSRS, Excel BI, and Tableau reporting. Production of dashboards, KPIs, SQL extractions, operational reports, and business steering tools.

SQL & Data Quality
Data analysis, SQL querying, consistency checks, cross-source reconciliations, variance analysis, anomaly investigation, data correction, and reliability.

Application Support / IT Analyst
Handling and qualification of incidents, database investigation, root cause identification, tracking fixes with technical teams, business communication, and process documentation.

Business / IT Coordination
Accustomed to international and multi-perimeter environments, I have worked with business stakeholders in finance, retail, supply chain, HR, subscriptions, and B2B. I know how to translate a business need into a BI solution or an analysis usable by IT/data teams.

My goal: to help teams have reliable data, clear reporting, and useful BI solutions that are maintainable and adapted to business needs.
