About Valentin

Former tech lead at Canal+, I specialize in Javascript and Scala (JVM) ecosystems, with solid experience in low-level programming (C, C++) acquired during my time at Epitech.
Passionate, fast-learning, and highly adaptable software engineer, I have nearly ten years of experience since my first line of code.
My expertise lies in designing and delivering high-performance software solutions that meet complex product needs, driven by a deep curiosity about the product.
I also have an excellent product vision and know how to intelligently orchestrate the convergence of business objectives and technical requirements, while reasonably managing technical debt.

    In 2023, I was promoted to tech lead of one of the feature teams (10 people including 3 developers), where I led the internationalization of the MAM to absorb content from other MAMs, in various formats, physical locations, and languages.
