About Antoine

Available from 01/02/2023 full-time, part-time possible before this date if needed

CTO / Full Stack Developer / Devops / Passionate about AWS Cloud
I strive to satisfy the client as much as possible by offering them the best solutions that meet their needs. Agility, which I now practice regularly, facilitates this client satisfaction.

Key skills:

- Project Management / CTO: Building a technical team / Implementing Devops culture / Monitoring / Benchmarks / Requirements gathering / Steering / Facilitation / Proposing technical and functional solutions. All this in an AGILE context
- Frontend Development: applications, Websites / React / SSR (NextJS) / HTML CSS Integration / Responsive Design / UX / End-to-end test automation
- Backend Development: Architecture implementation / Service implementation / Creation of JAVA, NodeJS backends / Serverless / Python
- Solution Deployment: AWS cloud usage / Docker / Infrastructure as code (CloudFormation) / SSO / Deployment pipelines


These are the main skills, I can adapt to the context and learn other technologies. I believe that not knowing a technology should not be a deal-breaker. Indeed, my passion for IT drives me to be interested in several areas.
