  • Machine Learning Engineer at GearChain AI
    Jul 2024 - Sep 2024 · 3 mos

    I worked on enhancing the performance of the built in chat bot system, achieving an over 80% improvement in accuracy through advanced natural language processing techniques and prompt engineering. This was achieved through the improvement of the structured data retrieval-augmented generation (RAG) pipeline, optimizing the way data is retrieved and utilized for more accurate and context-aware responses. Additionally, I implemented a fast iteration cycle by introducing automated evaluation of the accuracy and improving code structure, enabling quicker experimentation and refinement of the chat bot.
