Back to original languageAbout David
Senior BI and Data Consultant with over 15 years of experience, I work with the business and IT departments of my SME and mid-cap clients on BI and decision support projects, from defining needs to providing reliable and usable indicators.
Most recently Head of Data & BI at ABILWAYS, I managed the group's BI roadmap, supervised a Data/BI team, and worked with the Finance, Sales, and Marketing teams on defining, validating, and leveraging their KPIs. I led the implementation of a structured BI platform (modeling, datamarts, quality rules), scaled to meet business needs without unnecessary cost or complexity.
My profile combines BI and decision support expertise with strong technical mastery (SQL, modeling, ETL/ELT, Power BI, Tableau), allowing me to bridge the gap between business needs, technical constraints, data quality, and cost/value trade-offs. I work pragmatically and iteratively, with progressive deliveries to quickly validate usage.
I primarily focus on BI project management, decision support platform structuring, data quality, and indicator management missions, favoring sober and open-source solutions where relevant, which are easy to maintain and economically controlled.
Skills: BI Architecture, KPI, Data Analysis, Data Quality, Data Governance, Data Engineering, SQL, ETL/ELT, Power BI, Tableau.
