About Cedric

Data / Cloud Azure architect and technical expert, I have been working for over 13 years on critical environments with high security and availability requirements. Specializing in databases and data platforms, I have led large-scale migrations (Datacenter to Azure, Azure to Snowflake), designed secure cloud architectures, and optimized SQL systems with high volumes and performance constraints.

My expertise covers the entire Azure ecosystem (Azure SQL, Data Factory, Functions, networking, automation, CI/CD) as well as the security of cloud and data environments (governance, access control, monitoring, compliance). A former CISSP, I bring a strong cybersecurity culture, both in architectural design and in operations and remediation. Recognized for my technical leadership, I support project teams on structuring choices, industrialization, and best practices.

    ENERGY AND UTILITIES
    January 2022 - March 2026 (4 years and 2 months)
    Bois-Colombes, France
    Data / Cloud architect and expert, I supported the data platform in its operations and transformation. I ensured daily monitoring, level 3 support, and the implementation of new data flows while guaranteeing security and compliance. I participated in T-SQL, SnowSQL, and PowerShell code reviews, and in technological watch to improve the platform.

    This mission included technical support for the migration of Azure databases to Snowflake, with target architecture design, development of Azure Functions for loading, and creation of a declarative deployment framework with static analysis. I also led the review of the security model and oversaw best practices for the operation and industrialization of data flows within a DevSecOps framework.

    ENERGY AND UTILITIES
    April 2018 - December 2021 (3 years and 9 months)
    Bois-Colombes, France
    As a Data / Cloud Architect, I planned and led the migration of the datacenter to Microsoft Azure, defining the technical roadmap and key project milestones. I designed the target architecture to ensure performance, security, and resilience, while developing infrastructure as code and implementing application CI/CD via Azure DevOps to industrialize deployments.

    I also designed and supervised the implementation of data routing components with Azure Data Factory and Automation, optimizing data flow processing and circulation. My role included defining and applying Cloud best practices, participating in the development of Azure standards, and supporting teams in adopting new processes, thereby ensuring a smooth, secure, and sustainable migration of all systems.

    HEALTH AND WELLNESS
    April 2015 - March 2018 (3 years)
    Vincennes, France
    As a technical lead for the global product repository, I managed the complete migration from VS2005 / TFS2005 to VS2015 / TFS2017 and the upgrade of the .NET Framework from v2 to v4.6.1, ensuring application continuity and modernization. I supervised the continuous refactoring of components, replacing .NET Remoting with WCF and WinForm with WPF, while optimizing SQL performance and application code.

    I implemented C# and SQL unit tests, created SSRS reports, and industrialized deployments via TFS and DACPAC. In a cross-functional role, I designed a dedicated development environment with 40 VMs, managed the VS2005 migration for other IT Europe applications, trained teams on TFS2017 / Git, and established a private NuGet feed. I also replaced VS packaging projects with Wix Toolset and set up a Confluence wiki to structure and share best practices within the department.

    This mission allowed me to combine technical leadership, application modernization, flow optimization, and team support, ensuring the robustness and efficiency of the product repository on an international scale.

I had the pleasure of collaborating with Cédric Gross, a data & cloud architect of exceptional caliber. As the true technical founder of our data & analytics platform, he led our entire cloud journey: migration from scratch from the datacenter to Azure, then best-of-breed modernization with Snowflake (medallion architecture & data mesh), establishing lasting standards for industrialization, governance, and performance. On the security front, his mastery is end-to-end: infra, network, identity, middleware, data, application, CI/CD. He designs resilient, hardened, compliant architectures without compromising product velocity. Some highlights Constant proposer, with a long-term vision. Very strong pedagogical skills: onboards tech & business, simplifies and aligns quickly. Clear, structured, constructive communication. Complete autonomy: from design to production, including in complex contexts. Rare ability to simplify and standardize critical topics (performance, costs, security). Impact area (excerpts) Azure & Snowflake: architecture, optimization, automation, governance. Multi-layer security: IAM/Privileged Access, network (segmentation, Zero-Trust), secrets & KMS, workload hardening, compliance. Industrialization: advanced CI/CD, testing, observability, SLO/SLA, FinOps. Data platform: medallion, lakehouse, data mesh, ALM, quality & traceability. Verdict: he is one of the very few profiles capable of designing, securing, and industrializing a data platform at scale. I recommend him without reservation for any critical mission requiring a reliable technical lead/architect and very high-level execution.
