Daraja was invited to make a presentation last week at the World Bank's ICT* Days in Washington. (Thanks to Twaweza for putting us forward for this.)
Rather than travel all that way for an 8 minute presentation, I was able to present from the Bank's Dar es Salaam office via Video-Conference. My presentation is below.
* For this conference, ICT is both a standard acronym (Information and Communication Technologies) and a more unusual one: Innovate, Connect, Transform.
