Stéphane Tetsing is an AI, Machine Learning, and Embedded Software Engineer based in Berlin Germany, with over 8 years of experience designing and deploying machine learning, NLP, and LLM-based solutions across healthcare, embedded devices, and Web3. He currently works as an AI R&D Consultant at Ethereum, where he integrates AI models into Web3-driven platforms, builds LLM-based infrastructure, and develops agent workflows and code-editing solutions.

Prior to Ethereum, he spent several years at the intersection of machine learning and regulated industries — leading R&D at Carepath Technologies, a telemedicine venture, where he oversaw ML compliance with medical device regulations (ISO 13485, ISO 14971, MDR), and at Hyfe Inc., developing wearable health devices for patients with pulmonary disease. His earlier work at BIOTRONIK involved applying machine learning and embedded systems engineering to implantable cardiac devices.
