Software Engineer Intern | Nextdoor
As a 2025 summer intern on Nextdoor’s Notifications team, I got my hands dirty in backend systems with massive volume demands and major business criticality. It was my first time building at production scale. It was daunting at first, but the challenge brought me great excitement. Empowered by stellar mentorship from Kevin Chai, I was pushing code to production in my first two days. I improved ranking logic for Local News emails, boosting click-through rate by 14.8%, and built a more personalized, topic-based email selection process that reached over 10M sends during my time as an intern. I also built an internal React + GraphQL tool that cut ML model debugging time by 97%, allowing the team to ship notification features faster and with greater confidence.
