Back to original languageAbout Gaël
Initially a Java/JEE developer for over 10 years in various sectors (Banking, Insurance, Publisher, E-Commerce...), and a convinced Agile practitioner, I have focused for over 8 years on Big Data architectures and the role of Data Engineer/Data Scientist (Kafka, Spark, Cassandra, Hadoop, ELK...). I have also supported the evolution and migration of Big Data platforms from 'on-premise' solutions to the Cloud (IaaS, SaaS).
I have a rather horizontal approach to work organization and team responsibilities to try to maximize collective intelligence and to best express everyone's desires and skills within a group.
If you are looking for someone to solve your data flow optimization problems or technical, architectural and/or operational issues related to Big Data (AI, Machine Learning, IoT, blockchain...), do not hesitate to contact me, I would be delighted to discuss it.
