About Bastien

Looking to integrate AI into your products or industrialize your models? I design and deploy AI components (NLP, computer vision, machine learning) via Dockerized FastAPI APIs, backed by 10 years of full-stack web development and lead dev experience.

My strength: I bridge the gap between models and production. Where many stop at the notebook, I bring a true software engineering culture (architecture, testing, CI/CD, maintainability) to deliver reliable and deployed AI features.

What I can offer you:
  • Integration of AI features into existing applications (LLM, vision, custom models)
  • Model development and deployment: Python, PyTorch, Keras, Scikit-learn, FastAPI, Docker
  • Transfer learning & fine-tuning: NLP (CamemBERTv2, sentiment analysis), vision (CNN, YOLO, image classification)
  • Custom web applications & REST APIs: Symfony, API Platform, React/Vue
  • Refactoring, migration, performance optimization

From developer to lead developer, I have managed teams and led complete projects, from scoping to production. Quality, testing, CI/CD, and good architecture practices are at the core of my work.

Available for full-stack development (with or without AI components), adding AI components to your applications, technical refactoring, or team reinforcement on long-term missions.
