Back to original languageAbout Sofiane
I am Sofiane, a developer engineer (full-stack, software, web & mobile). A builder of projects and an entrepreneur, I enjoy creating, supporting, and transforming ideas into concrete products (prototypes, MVPs, and scaled products).
With 7 years of experience in France and Japan in high-tech companies like Safran, Valeo, and Sagemcom, I have held various roles: developer, architect, team leader, designer, tester, etc. I bring technical expertise in common languages and frameworks (non-exhaustive list: Python, Java, C++, C#, SQL, JavaScript, Node.js, React, Dart/Flutter), as well as know-how in product design, project management, DevOps, and testing.
I work remotely or on-site as needed, on short or long missions.
Tell me your needs, the context, and the constraints (budget, deadline, confidentiality, etc.). And let's discuss together how to best achieve the project in a concrete and realistic way!
