Backend Technical Lead at Groupe Sonatel, owning the Maxin HR platform backend and its secured APIs, modules, and AWS migration.
SenegalAt Groupe Sonatel, I own the backend lifecycle of Maxin, a mobile HR platform for employees, shareholders, and retirees. I designed its architecture and developed secured REST APIs, access controls, and core HR modules.
I also led the DevOps infrastructure migration toward AWS and GitLab CI, and set up CI/CD pipelines with Jenkins and OpenShift Container Platform. Previously at Groupe Sonatel, I developed the Orange Money card top-up API and built Orange Battle Game for Dakar Digital Show 2018.
