AI USER ONBORDING

Middle Full-Stack Developer

About the Project

I played a key role in developing a SaaS application designed to revolutionize the initial user experience. We implemented Large Language Models (LLMs) to intelligently parse natural language queries, allowing the system to conduct intuitive, conversational interviews with new users.

Responsibilities

The main objective was to automate the onboarding process by extracting key data points from user responses. Shifting from rigid forms to an AI-powered dialogue significantly lowered the barrier to entry and allowed us to gather deeper insights into user needs from the very first interaction.
