Description

With 5 years of experience at Criteo as a software/data engineer, followed by 2 years at Contentsquare and Société Générale, I offer my assistance in implementing your Scala/Java systems.

I have worked on several complex Scala/Java systems involving multiple data sources (web APIs, databases, Hadoop File System, etc.).

I prioritize efficiency in my work, always avoiding over-engineering and favoring the simplest solution that yields the best operational result.
