Experience
RIFF Framework
https://github.com/rohatsu/riffTargeted at developers, the framework provides an environment for programming logic processors that are automatically arranged and triggered in dependency order. It also exposes a range of ready-to-use technical interfaces for common integrations (FTP, Excel import, etc.) and system tasks (logging, permissions, etc.) as well as a key-value data store.
Its goal is to eliminate code repetition between similar projects and reduce their development time and effort. The framework is targeted at modeling processes and workflows that amalgamate data from multiple sources and has been successfully incorporated in multiple clients' production systems.
