About Baptiste

🎯 GCP DevOps & Flutter/Firebase Developer — Creator of tailor-made Cloud and Mobile solutions


Computer Science graduate engineer, currently employed full-time at Onepoint (on assignment at Système U), I offer my freelance services **evenings and weekends**, with a dual focus:

👉 Flutter/Firebase Mobile Development:
Specializing in Flutter, I have deployed several applications (professional, personal, and freelance), integrating advanced features: **Firebase Auth, Stripe, Google Maps, API integration, NestJS backend, Cloud Functions, and store deployment**. My approach covers the entire chain: **from mockup integration to Cloud deployment**.

👉 DevOps & Google Cloud Platform:
I design and automate scalable Cloud infrastructures, leveraging tools like **Terraform, GKE, Cloud Run, CI/CD (GitHub Actions, GitLab CI), and Vault**. I have contributed to Cloud migration and architecture modernization for companies like **Windle or Système U (a major player in mass retail)**, by implementing pipelines, containerization, serverless, and robust infrastructure-as-code management.

đź’ˇ What sets me apart:

A **360° vision**: mobile + backend + infrastructure = a single point of contact for your projects.
Strong innovation capacity through active technological monitoring (Langchain, OpenAI, generative AI, etc.).
Concrete experience with startups, IT service companies, and large corporations, allowing me to adapt quickly to your processes.

Weather Journey:immersive weather app with ChatGPT, Midjourney & Lo-Fi music
Windle:Flutter CI/CD, GCP Cloud deployment, mobile app development for installers
