What we learnt building BHIM in just 3 weeks - Vimal Kumar 

How functional programming techniques and a fully Javascript based app development platform helped us to build BHIM & *99# in 3 weeks.
We created BHIM and it’s USSD counterpart *99# in just 3 weeks. This was primarily because of adoption of pure functional programming techniques and usage of a custom built javascript based app development framework. Javascript unified multiple platforms
and had an impact on reducing the overall effort. Functional programming techniques enabled multiple teams to work in a hyper parallel mode and assemble components in a robust way in a short timespan. Here we share our learnings.
