About Nicolas

Hello!

I am a data engineer developer, used to working with Agile methods for 9 years. Beyond the code, I like to take an interest in my client's business and the context of the project. Thus, I can serve as a link between the business and the tech as well as take on the role of "tech lead".

I also like to do devops.

I have worked on various projects with Scala, Spark, Python, both on on-prem Hadoop clusters and in the Google Cloud Platform. I also have a little machine learning experience in Python.

My mantra: *It's simple to make complicated code, but it's complicated to make simple code*

I am looking for:

  • Data missions with Scala/Python, cloud
  • Nice and motivated colleagues because I am a good group emulator

I like:

  • Python, Scala, Spark, GCP, Machine Learning
  • Devops
  • Technical challenges
  • Very clean and very readable code
  • Well-tested code

The technologies I know:

  • Scala, Python

  • GCP tools: BigQuery, BigTable, Composer, Cloud Storage, Dataproc, Pub Sub, Dataflow
  • Sbt, Git, Jenkins, GitlabCI, Ansible, Docker, Terraform
  • Linux
