# Jonathan Yee > Full-Stack Engineer at Reshop | 4 Years Fintech | TypeScript • Ruby on Rails • React Native • AWS Location: San Francisco Bay Area, United States Profile: https://flows.cv/jonathanyee Full-stack engineer with 4 years of fintech experience at Reshop, working across our entire platform that transforms e-commerce refunds. I've built features spanning our mobile app (React Native/TypeScript), backend payment systems (Ruby on Rails), and authentication flows. Currently leading our analytics infrastructure from the ground up—working with product and marketing teams to understand their measurement needs, then collaborating with engineers across teams to implement tracking solutions throughout our codebase. The system now processes ~3k events daily, driving key business decisions. I thrive on taking ambiguous requirements and turning them into technical solutions. I'm passionate about being a product engineer: someone who thinks end-to-end about both the technical architecture and the user experience, seeing the whole picture rather than individual pieces. Outside of work, I build full-stack applications that solve real problems—like SecondThought, an AI-powered thought organization platform that helps users transform scattered ideas into actionable plans, and Patine, a smart meal planning app with intelligent recipe management. ## Work Experience ### Software Engineer @ Reshop Jan 2023 – Present | San Francisco Bay Area • Lead the design and
