I returned to Hopper as an ML Engineer on the Wallet & Subscriptions team, where I optimized our products and built predictive models. I was then transferred into Customer Service Data, working on AI LLMs to reduce our costs of service. I've specialized in NLP, scrubbing sensitive personal data and gleaning actionable insights from millions of conversations. My work has achieved a better understanding of these contacts, bringing greater efficiency to our $50-million-per-year global customer service operation.

I took the initiative in solving our team's greatest problem: fraud in the user referrals program. I independently designed, built, and deployed a bespoke ML system to block fraudulent referrals, using information-theoretic concepts for anomaly detection. My work continues to block fraud worth at least $3.5 million per year, with an exceptional 98% accuracy. Thanks to my contributions, referrals remain as an indispensable component of Hopper's consumer strategy.

During my freshman winter, I worked as an undergraduate TA for CS-10: Problem Solving via Object-Oriented Programming. The course focused on OOP in Java and taught concepts including data structures, recursion, multi-threading, and introductory machine learning. I led weekly tutoring sessions, held office hours, and graded exams and labs.

After attending as a camper for many years, I worked at Camp Manitou for two summers as a counselor. My responsibilities included supervising children aged 6 to 12 and organizing fun camp activities. I developed important social skills by mentoring other camp staff, and working with young children pushed me think critically and creatively when solving problems.
