ValuesFit is a platform that helps candidates and companies find the right fit. This was made using Rails and React and deployed to DigitalOcean, AWS (S3 and cloudfront), and Cloudflare. There are several components to this project - Kanban type job management platform, file hosting, chat between candidates and companies, a feedback service, chrome extension(https://chrome.google.com/webstore/detail/valuesfit-extension/fohmkolmaljakbbnomjpfgbiplgmlcmh?hl=en) and a job listings section. Needless to say it's a work in progress.
