About Stéphane

Pragmaticand business-oriented, I assist you in solving your problems with an approach adapted to your strategic challenges.

Fullstack architect, developer, and DevOps engineer, I support you through all phases of your project, from ideation to market launch.

My interventions include:
  • As an **architect**, defining functional and then technical components. I select with you the best solution architectures that address your challenges.
  • As a **Tech Lead**, providing technical and strategic guidance to teams, fostering skill development and the transmission of best practices.
  • As aDevOpsengineer, setting up your CI/CD delivery pipelines and your Cloud environments (AWS and GCP experience) using Infrastructure as Code (Terraform, CDK, ...).
  • As a fullstack **developer**, building the various components required to deploy the product.
My primary development stack is Java (Kotlin)/TypeScript/Angular, but I also work with other languages and frameworks (Golang, Python, Rust, ...) and I am eager to learn new technologies.

I also offer my services as an Alexa Voicebot developer.
