Back to original languageAbout Mamadou Dian
👋 Cloud & Backend Engineer – specializing in business orchestration, automation, and Infrastructure as Code.
With over 10 years of experience, I help companies automate and make their critical business processes more reliable: activations, onboarding, data pipelines, provisioning, etc.
🎯 My approach
I combine backend and infrastructure development to design traceable, scalable, and automated systems capable of adapting to complex and multi-tenant environments.
🧠 My expertise:
• Workflow orchestration (Airflow, Prefect, Kestra, CI/CD, BPM)
• Infrastructure as Code (Terraform, Kubernetes, multi-cloud – GCP, IBM Cloud…)
• Backend development (Python, Java, Kotlin, FastAPI, microservices, event-driven)
💡 Curious, pragmatic, and business value-oriented, I work closely with teams to transform complex problems into fluid and robust solutions.
📬 Open to opportunities – and always up for discussing your Cloud & Backend challenges!
