Jack Leitch is a Data Platform Engineer @ WHOOP at WHOOP. Colleagues describe him as "I had the pleasure of working with Jack for four months while at Olive, where we collaborated on various components of Olive's AI platform for Payer solutions. Jack hit the ground running within the group, immediately providing valuable contributions to architecture, ML ecosystem, and medical rule construction. He then continued on to construct major components of a new system, and now leads the effort to productize AI services, already delivering a successful proof-of-concept. Jack joined the organization with significantly more knowledge and expertise than I would expect of any recent graduate. More importantly, it quickly became apparent that he is an expert learner, rapidly growing his skills of software development, system architecture, and project management. More than once, Jack started a week being unfamiliar or inexperienced in a topic, and ended the week writing design documents or participating in conversations in a way that exhibited a thorough understanding. Beyond his capability as a learner and a doer, Jack is a team player. It was not uncommon to see him lend a helping hand or jumping in to assist with a tricky issue. He gives others the room and encouragement to share their ideas in conversation, while not being afraid to share his own. He figures out the best path forward in situations with limited clarity, understanding the impacts to the group and its responsibilities, initiatives, and objectives. I am confident that Jack will be a major benefit to any organization, whether continuing to eliminate healthcare administration inefficiencies at Olive, or with some future group. Given his wide range of skills and capacity for learning, he would be highly effective contributor in a wide variety of software- and data science-related roles. To anyone reading this recommendation, try to schedule 30 minutes with Jack to discuss your job opportunity or big idea - you'll be glad you did." and "From the day I participated in the interview panel to bring Jack on board, it was evident that Jack possessed not only the technical prowess, but also abundant sense of responsibility, inquisitiveness, and flexibility to be able to begin contributing to the team almost immediately. Upon starting, Jack's meticulous curiosity helped identify pain points for operational improvement. He was able to quickly grasp and make meaningful contributions/improvements to the codebase while still adhering to the organizational guidelines. Jack is an incredible individual and asset to lift any team's standards as a whole in terms of statistical analyses, programming, feature development, or any other skill your team may be hoping to have scrutinized and improved."
