Védric accompanied us over the long term in structuring our processes. The mission involved setting up automated CI/CD processes ensuring end-to-end traceability, reviews and validations, and a quality, secure production deployment. It also included delivering numerous genomic analysis tools in containerized form, applying CI/CD processes and standardization. This mission was extended to finalize our CD (GitOps model) for publishing container images to our HDS infrastructure. The challenge was also to ensure a smooth transition and knowledge transfer to team members. Védric handled all tasks within the short timeframe of approximately 2 weeks (in May). True to himself during this extension as with the rest of his missions within our team: comfortable presenting his work, documenting it technically, providing complete reports, professional, cheerful, attentive, and available with a genuine desire to share knowledge. Currently, the team has been able to resume and continue the work without issues, relying on the information transmitted but especially on the complete documentation that Védric put in place throughout the mission. I recommend Védric and would be delighted to entrust him with new missions.
