DevOps Engineer | CI/CD Automation | Technical and Product Support in the Social and Solidarity Economy 🌱
Are you a Social and Solidarity Economy (SSE) organization looking to stabilize your deliveries while streamlining collaboration between technical and product teams? I help development teams strengthen their DevOps culture and automate their CI/CD pipelines, while supporting POs/PMs in the operational management of their tech projects to ensure a more stable, better-prioritized, and clearer product for everyone.
I am a DevOps Engineer, specializing in setting up automated environments, infrastructure as code management, and simplifying delivery workflows.
On the technical side, I work on setting up CI/CD pipelines, containerization (Docker, Kubernetes), infrastructure as code (Terraform, Ansible), and environment monitoring. I support SSE organizations, startups, and IT departments in modernizing their deployment processes, migrating to the cloud (Azure, AWS, GCP, or others), and upskilling their internal teams.
A solid product relies as much on its technology as on the clarity of its management. I help Product Owners and Product Managers structure their collaboration with developers: clarifying technical needs, realistic prioritization, synchronization with CI/CD cycles.
Each mission is designed to be turnkey: automation, documentation, and knowledge transfer. You will leave with a stable and scalable environment, and a more autonomous team, both on the development and product sides.
In terms of methodology, I use adapted agile workflows, systematic continuous integration, and clear communication so that developers, POs, and PMs move in the same direction.
If you want to accelerate your deliveries, stabilize your environments, and improve communication between product and tech, contact me for a video call.
