About
I’m Yassine Cheffai, a full-stack software engineer with 10 years of experience designing robust, high-performance, and easy-to-maintain web architectures. I enjoy turning complex needs into clean, well-structured solutions—from gathering requirements and planning with Agile teams to delivering production-ready features with strong attention to reliability and maintainability.
My day-to-day work spans Python backends (Django, Flask, FastAPI), React frontends, and DevOps practices using Docker, Kubernetes, AWS, and CI/CD pipelines. I also care deeply about quality, leveraging TDD and clean architecture principles, and I love supporting teams end-to-end, from analysis and implementation to deployment and monitoring.
