I am a machine learning engineer with over 20 years of experience. I have worked with innovative companies such as Airbnb and GitHub, which included early LLM research used by OpenAI, for code understanding. I have also led and contributed to numerous popular open-source machine-learning tools. I am currently an independent consultant helping companies build AI products.
