About Salah-Eddine
I am a software engineer with experience in Backend and Cloud development, and a background in Data Science that has helped me develop strong analytical and problem-solving skills. Over the years, my experience has evolved—starting with Python development in Data Science, then moving into Django, Flask, and FastAPI for backend services. I also work with AWS cloud solutions and Power BI for data visualization. More recently, I’ve been focusing on Cloud/Data Engineering and integrating Large Language Models (LLMs) into scalable applications.
