Freelancer profile translated to English.

Description

With now 9 years of experience and 4 missions accomplished in the field of data engineering, I am choosing freelancing for the continuation of my adventures.

I will support you from the beginning to the end of the development cycle, from understanding the need, its development and testing phase, deployment automation to the production and application maintenance part.

My preferred language is Python, but I remain open to other languages.

I have had the opportunity to work in relational environments (SQL, Oracle, Postgres) as well as in Big Data environments with high volumes (Hadoop, Spark, Hive, Elasticsearch).
