Senior software engineer, architect and tech lead with six years building freight, booking, e-learning and fintech platforms for companies in France, Germany, the UK, Canada and Tunisia. I take engagements end to end — turning business rules into an architecture, building the backend in Python, Django and FastAPI, and shipping it to production on Azure, AWS or GCP with proper CI/CD. On the AI side I build systems that hold up under real traffic rather than demos: LLM assistants and agents on OpenAI, Claude and Gemini with function calling wired into live business systems, RAG pipelines built for retrieval quality and evaluated properly, and ML models deployed and served in production with cost and failure handling designed in from the start. I also lead teams while I build: architecture ownership, code review and engineering standards. Available worldwide for remote missions, contracting through PYTUNITY, my Tunis software studio.
