I went to an event once where a Twilio developer evangelist presented and he did the live coding exercise. Using flask he wrote a quick server, and started receiving text messages from the audience in about 5 minutes. Then he applied a NLP library to the text messages, all in all quite impressive.
Rob was a regular at PennApps, the hackathon where I cut my teeth. He was among the most helpful & friendly of any sponsors, helping debug code that didn't involve Twilio at all. He also provided valuable "hackathon strategy" advice like "don't build that feature" to young coders who needed it.
I'm sure Twilio's success is due in no small part to dev evangelists like Rob, I hope he's well rewarded for it.
Here's a copy of his presentation, it was pretty awesome to watch. https://github.com/RobSpectre/Talks/tree/master/SMS%20For%20...
