Fieldfolio AI was an AI-powered recommendations engine I built for the Fieldfolio marketplace, to help buyers discover sellers they might want to order from. When a buyer signed up or returned to the platform, they’d be shown a set of recommended sellers – “Sellers for You” – and could request wholesale pricing from any of them in a click, starting a connection with that seller.
Under the hood it was built around a Weaviate vector database, which we used to vectorise information from across the platform, together with the OpenAI API. I led the project as the lead developer and architect, with a developer on my team helping on the build.
It was built on Fieldfolio’s stack – Ruby on Rails, MySQL and GraphQL on the backend, with React and Next.js on the frontend – plus Weaviate and the OpenAI API powering the recommendations engine.
