Rockstar🎓
Top SchoolJulien Chaumond is a seasoned AI entrepreneur and engineer with 16 years of experience, currently co-founder and CTO at Hugging Face, where he helps shape the open AI ecosystem from tooling to community. He blends deep academic training from Stanford, École Polytechnique and Télécom Paris with hands-on engineering across full-stack, backend, and ML projects—ranging from core contributions to Transformers and the Huggingface Hub to mobile CoreML ports of NLP models. Julien has a track record of founding and scaling startups (Glose, Stupeflix) and shipping production ML-enabled products, including an Apple-featured app acquired by GoPro. An active open-source maintainer, his commits span critical repos for model conversion, dataset tooling, web UI, and server infrastructure, showing comfort from low-level sockets to rich client experiences. He also brings public-sector advising experience on digital affairs and a penchant for making complex model and data workflows accessible to broader developer and researcher communities. Less obvious: his cross-language fluency—from Swift and Node bindings to Python ML libraries—enables him to bridge research prototypes to real-world deployments.
