Check out Fast Forward, an accelerator focusing exclusively on non-profit tech startups: https://www.ffwd.org . Y Combinator now also has a track for non-profits - https://www.ycombinator.com/nonprofits/ and for example funded https://watsi.org/ .
Feel free to ask questions. I volunteered at Grameen Foundation and have been exploring this space for a while.
Could you explain what type of tasks you do? How does one get a job like yours?
I got here by working in non-profits for many years as an operations person, learning database technology, and then finding a firm that combined those two!
Yes, Salesforce integration is on the roadmap - we get many requests for this.
