About Théo

I'm a Python expert with 4+ years building scalable APIs, automating data pipelines, and managing backend infrastructure on GCP. I’ve delivered projects for companies like L’Oréal, using FastAPI, Django, SQL, and BigQuery to build real-time, production-grade systems.

I am particularly proud of the positive feedback I have received from the companies I’ve worked with, attesting to the quality, reliability, and performance of the solutions I’ve developed. These experiences have allowed me to refine my ability to understand and meet the specific needs of businesses while remaining flexible and innovative in my approach.

As a dedicated and passionate professional, I am always on the lookout for new challenges and exciting projects where I can make a significant contribution.
