Valentin Kasas is a Lead Engineer based in the Greater Paris area with 11 years of experience building backend systems and guiding teams across enterprises and startups. A longtime Scala specialist and functional programming advocate, he combines hands-on development as a freelance consultant with leadership roles at Xebia and 47 Degrees. His background spans technical leadership at public-sector and large corporate clients (La Poste, MNT) as well as teaching Spark internals, reflecting both deep systems knowledge and an ability to transfer that knowledge. Comfortable across JVM ecosystems and distributed data platforms, he often bridges architecture, coaching, and implementation to deliver pragmatic, testable solutions. Notably, he pairs industrial engineering experience with early-career game programming roots, which gives him a practical, performance-minded approach to problem solving.
