Rachid Jeffali

Senior Python Developer and Technical Trainer

With over 5 years of experience as both a developer and instructor, I operate at the intersection of hands-on software engineering and pedagogical support. I train individuals undergoing career transitions or upskilling, with a focus on Web and Backend technologies, while actively contributing to production-grade projects.

As a Python developer specializing in machine learning, I currently work on a semantic analysis project designed to evaluate web pages based on values upheld by the organization. I have built an end-to-end pipeline involving data scraping, preprocessing, predictive modeling, and content scoring — with a strong emphasis on automation, performance, and maintainability.

My development approach is pragmatic and grounded in architectural best practices (DDD, TDD, Clean Architecture), code quality, and security. I bring a production mindset to both my code and my training sessions: comprehensive testing, CI/CD, modular design, and clear, maintainable documentation.
