About Dieudonné Mayi

I’m a data architecture and analytics leader with 20+ years of experience designing, scaling, and modernizing enterprise platforms, from cloud migration and reporting optimization to regulatory governance and insight delivery. My work centers on architecting data ecosystems that turn complexity into clarity—bridging technical execution with business impact. Whether migrating 60+ enterprise databases to Azure, delivering real-time BI for Fortune 5 leaders, or implementing compliance-ready data frameworks, I’m brought in when performance, precision, and partnership matter most. I’ve built full-stack data solutions across industries and led globally distributed teams through multi-cloud transformations. My strength lies in connecting architecture to outcomes ensuring every pipeline, model, and dashboard delivers business value at scale: Data pipeline orchestration using Azure Data Factory, Databricks, SSIS, and Matillion Data warehousing & modeling with Synapse, Azure SQL, Snowflake Executive-ready BI using Power BI, DAX, Power Query/M, SSRS, and SSAS Tabular Performance tuning and data optimization across SQL Server, Oracle, and PostgreSQL Cloud platform integration across Azure (ADF, Synapse, Analysis Services), AWS (S3, EC2, Redshift), and hybrid environments Governance and compliance including SSN/PII obfuscation, encryption, and secure architecture Cross-functional collaboration with engineering, finance, operations, and compliance teams : Power BI, SSRS, Tableau, Alteryx, Excel PowerPivot : Python, T-SQL, C#, C++, JavaScript : Azure Synapse, ADF, Databricks, Analysis Services, Azure SQL DB, Snowflake, AWS S3/EC2/Redshift, Oracle SQL, PostgreSQL & : SSIS, SSAS (Tabular & Multi-Dimensional), DAX, Power Query, Kusto : Data privacy enforcement, regulatory compliance tooling, metadata & lineage tracking & : End-to-end dashboarding with backend logic, semantic layers, and front-end design If you’re building for scale, governance, or modernization in your data ecosystem—I’d be glad to connect.
