About Crystal Lemire

Currently gainfully employed at HNT Labs, where I'm helping to build out the Towns protocol.As a Software Engineer at dYdX, I worked on building and maintaining a scalable and secure platform for trading crypto assets on a decentralized exchange. I use Go, Cosmos, and other technologies to develop, test, and deploy backend services and APIs that handle high volumes of transactions and data.Most recently at dYdX, I built, deployed, and monitored the dYdX chain, using Go, Cosmos, and other technologies. I owned the oracle pricing module and the prices daemon, and reduced block rejections during periods of price volatility by over 80%. I also built and deployed the delay-msg module, which supports the ethereum bridge for dYdX tokens.. I have a strong background in mathematical and computational science, having graduated from Stanford University with a B.S. and a graduate degree in Computer Science. I have also received multiple fellowships and certifications for my mentorship and research and skills in high performance computing. I am a self-starter, a quick learner, a strong communicator, and a mentor to others. I am passionate about creating innovative and impactful software solutions that make the world more open and connected.
