At ADDOAI, I developed machine learning and generative AI solutions for customer interactions, including NLP models for chatbots and voice assistants that increased customer satisfaction by 30%.

I built a document-based chatbot with LangChain and Streamlit that reduced query handling time by 40%, and created an agentic workflow with custom LangChain tools that improved customer support efficiency by over 30%. I also developed a drift detection pipeline and an automatic feature selection pipeline for lead scoring.
