About the Project
I was initially hired via Toptal to refactor and clean up this Unity-based virtual human system, which became the foundation for all future HIA products. The system featured sophisticated 3D character animation with dynamic gesture systems, advanced lip-sync technology, and AI conversation capabilities through DialogFlow integration. After proving my value in the initial cleanup, I became the core programmer, developing key systems including the natural body language generation, multiple text-to-speech integrations, and comprehensive speech recognition. This work established the technical foundation that would later scale to serve hundreds of healthcare organizations.
