Rentoo brings security and trust to renting for landlords, tenants and lenders.
Lead a team of five to build the software to automate the entire lettings process in the UK from start to finish. The product features fully automated reference checking, signing and uploading tenancy agreements and a payment and billing system.
Outside of building the business and the team, I was hands-on with every aspect of the development for the product, both on the front-end, design and back-end. The front-end is built in React and Redux (ported over from Angular), and the backend is built with Node, Express, Mongo and Elasticsearch.
We use LangChain for extracting open source data to generate listings and area guides using various LLMs. We also run our prediction models for rent prices and credit risk on VertexAI.
We run our main application using docker containers with Kubernetes on Amazon EKS with smaller microservices running on Fargate. For object storage we use S3 together with Lambda. We also use Redis for caching purposes.
Raised £300K in investment, continued to bootstrap the company and it currently generates a six figure ARR.
