💼 Past Experience

monster.ioEmployer: TwitterLocation: Seattle, WA working in a wide cross-section of software engineering including: front-end, back-end, and algorithm development.Ultimately, my experience at Twitter was as a Technical Lead, responsible for a product safety infrastructure that manages real-time rules needed for Twitter’s products.

This engine is used to enforced acceptable use policies for both the company’s public forums and the Twitter application itself.Being a Technical Lead at a large tech company is humbling. I was responsible for numerous projects that required delicate and complex *fuzzy* math, and my experiences with chaos and noise led me to develop a solid understanding of how to deal with these challenges. Additionally, I was constantly learning new things and growing as a engineer, which was extremely fulfilling.
