I've been working on something very similar to that. It allows you to connect a SQL database, S3 bucket, etc. then write a query for the data that you want to train the model on. It takes a couple minutes and then it'll expose the trained model over a REST endpoint. It also has feedback loops to fine tune the model on real-time data and has an option to store all the predictions made by model into Redshift or S3 to be visualized on a tool like Tableau. The tool itself is not open-source but it can be installed on the user's AWS, Azure, or GCP account to keep their models and data private. It's still in alpha testing (bunch of pilots) and I'll probably do a "Show HN" post when it is ready for a public beta
