I've been an engineer at Periscope for the past couple years and would be happy to answer any questions about the company or life as an engineer here.

I've worked on the whole stack here, but my favorite parts have been new charting features (most recently annotations), client and server side latency (I love the chrome flame graph profiler), machine learning for lead scoring models (hooray for scikit), and anytime we can ship a customer feature request the same day they request it.

Send me an email at ganz@periscope.io if you'd like to talk about life at Periscope! :)
