Summary
I optimize your ML and NLP models and implement MLOps solutions to bring your AI projects to life!
Machine Learning Engineer with 5 years of experience, I have contributed to the production of several AI products at Ubisoft, GitGuardian, and Sanofi from end to end. I have worked on complex topics such as:
- E-commerce fraud detection (xgboost, feature engineering, MLOps, AWS, Kubernetes)
- Deployment of state-of-the-art NLP models for detecting secrets in source code files (Transformers, Pytorch, FastAPI, ONNX Runtime, AWS Kubernetes EKS)
- Development of a complete Terraform module for an unstructured data processing pipeline: Transforming PDF, PPTX, DOCX files into vectors in Pinecone (LLMs, multi-modal models / VLMs, OCR, Terraform, AWS, Weight's and Biases Weave)
My skills
ML / NLP / AI:
- Training and fine-tuning of classic ML models and LLMs / VLMs
- Agents
- LLM FinOps: cost/performance evaluation (OpenAI, Bedrock, Benchmarks…)
MLOps / LLMOps:
- Deployment of AI services: microservices, APIs, batch jobs
- Implementation of MLOps best practices: reproducibility, versioning (DVC), CI/CD, Docker, experiment tracking, scalability
- Software Engineering: PEP8, clean, documented, and modular code, error handling, monitoring
- Multi-cloud: AWS, Kubernetes
- IaC: Terraform
Data Engineering:
- Orchestration with Dagster, Airflow
- Development of ETL / ELT pipelines (pyspark, snowpark)
- Snowflake, Hadoop, PostgreSQL
Stack
Python, PyTorch, OpenAI, Bedrock, Weights and Biases, DVC, Skypilot, ClearML, Mlflow, BentoML, ONNX Runtime, Streamlit, Grafana, Tableau, Docker, Gitlab CI, Kubernetes, Helm, ArgoCD, Terraform, AWS, Dagster, Airflow, Hadoop, Snowflake
