About

After spending several years as a software engineer at fast-growing startups, I launched my own suite of developer tools aimed at making deployment and monitoring effortless. I hold a degree in Computer Science from NYU and have interned at leading tech companies in New York and Seattle. I've also competed in over 15 hackathons and spoken at regional developer conferences. I thrive at the intersection of elegant code and great design.
