    Missions: Leading the architecture, migration, and development of Air Liquide’s Data Platform on AWS.
    • Leading and collaborating:
    - Led the migration of the platform from Air Liquide’s corporate host to Claranet’s AWS host (Because Claranet
    holds the HDS (Health Data Hosting) certificate, it was chosen by Air Liquide to deploy the platform in production to be
    HDS compliant)
    - Worked tightly with the head of the data platform and Claranet’s team to structure the migration of the
    platform
    - Succeeded in leading the team (+10 pers) to put two use cases into production under a very challenging
    deadline
    - Led and coordinated meetings with different stakeholders, teams, and product owners to discuss, architect,
    and evolve the data platform
    - Established backlogs and organized the tasks’ dispatching to different actors of the data platform
    • Architecting:
    - Challenged and optimized the existing architecture of the platform (cost optimization, resource’s distribution,
    API calls, networking, security and IAM roles, etc...) to harden the platform’s operability and pare down major
    incidents.
    - Produced architecture documents which became the reference to go to when auditing the platform
    - Architected and developed new features on the data platform (different connections to on-premisessystems:
    data replication with DMS and Qlik Replicate, file transfers to on-premises systems, etc…)
    - Designed and developed different CloudFormation stacks of the data platform
    - Developed automation tools to accelerate the platform’s deployment (script generation, etc.…)
    - Deployed Jenkins pipelines to automate the platform’s deployment on different environments
