David Mostoller
Senior Software Engineer · Network Security
I'm a senior software engineer on Comcast's DDoS Mitigation Services team, building the internal tools, intelligence platforms, and automation that security engineers use to protect one of the largest networks in the U.S.
Outside of software, I produce electronic music as Kabayun and Superluminal, drawing on a background in audio engineering and music technology.
When I'm not coding or making music, you'll often find me on my bicycle or lost in a sci-fi novel.
