Low-level Backend Engineer

Ideal roles: firmware/low-level, high-traffic, large-scale backend service work (working w/large data sets that need bespoke engineering), "impossible" technical challenges. I've done everything up and down the stack from low-level assembly up to massive web-scale work. Most recently I was a director of engineering at FullStory, focused on a mobile analytics product that I built from zero, wrote patents for, and hired up a team to take over. I'm looking more at low-level work right now at a small company with good culture. I'm also happy to discuss any other interesting opportunities, especially if they come with difficult and interesting problems.
