I finished Data Commander (MVP) - http://conceptoriented.com - A web-app for column-oriented data transformations.

After getting some feedback I decided to position this technology differently. Instead of exposing the functionality via web app, I started implementing a Java library http://github.com/asavinov/bistro - an alternative to map-reduce. In 2018 I am going to develop a server for IoT and stream analytics - an alternative to kafka stream analytics based on Bistro.
