01.About Me
Hello! I'm Mahdi Sahami, a Python Backend Developer currently studying Computer Science at the University of Pisa, Italy. I have a strong passion for building software that solves real-world problems — from high-performance APIs to intelligent autonomous systems.
My focus is on crafting production-ready backends using Django and FastAPI, following strict engineering principles like SOLID, DRY, and Clean Architecture. I love the challenge of bridging traditional backend development with modern AI tooling.
Currently I'm interning as a Backend Engineer at Nexcore (Netherlands, Remote), where I work on scalable microservices and enterprise technical solutions.

API Latency
- Dual Architecture: REST API + autonomous AI agent executing real CRUD operations via Django ORM — eliminating HTTP round-trip latency.
- Engineering Standards: Strict SOLID, DRY, and "Fat Service, Thin Views" OOP patterns with complete type hinting throughout.
- AI Integration (RAG): Contextual company policy retrieval using ChromaDB and text-embedding-3-small for optimized cost and accuracy.
- 95% Test Coverage: 160+ automated tests across models, business logic, and AI tools. Full CI/CD via Docker and GitHub Actions.
