At Airbnb, I led several important initiatives that had an impact on the company's technology and growth. It includes rebuilding the dynamic config system, serving over 90% of Airbnb services, and orchestrating the creation of a read-optimized store system for millions of global listings(public data) with significantly enhanced performance and reduced costs. As a tech lead, I drove supply-side growth products($$$) and led hero projects in company-wide launch. I also played vital roles in improving media and address systems, guiding the SOA migration of critical product flows, and contributing to Airbnb's tech brand team which manages open-source projects and tech blogs from 2018-2020.
