Over the course of my career, I have gained extensive experience in developing and optimizing high-performance and scalable data publishing and caching services, as well as coordinating complex migration projects and tackling security/identity/authentication challenges in the fintech industry.During my time at Core System, I spent a year and a half working as a service owner, where I was responsible for optimizing the reliability and efficiency of a high-volume data publishing and caching service, which handled over 2 billion queries per second across more than 20,000 servers. My focus on optimizing memory, latency, and CPU usage resulted in a significant improvement in the service's SLA.At WhatsApp Core Infra team, I spent two years leading a migration project to transition more than 40 services from Erlang RPC framework to Thrift. As the project lead, I managed the end-to-end migration process, including performance testing, RPC framework implementation, and cross-service coordination, resulting in a more efficient and scalable infrastructure.In my last three years at Meta, I worked as part of the Security Infra team at Meta FinTech, where I played a crucial role in multiple crypto projects, including Libra, Novi Wallet, and Instagram NFT. My work focused on traditional payment account security, Web3 identity exploration (DID), and authentication, where I honed my skills in tackling complex security challenges while maintaining a seamless user experience.

ABC Blockchain Community is a Bay Area-based non-profit organization focused on promoting and educating the public on the benefits and applications of blockchain technology. As the president of the community, I played a pivotal role in developing and leading several educational programs designed to engage blockchain enthusiasts, including students, researchers, and developers across all tech companies.Under my leadership, we launched a variety of initiatives, including an entry-level course to introduce BTC/Ethereum, white paper reading, bi-weekly offline tech sharing and panels, and hackathons. These programs were designed to attract thousands of members and provide them with opportunities to learn and grow their skills in blockchain technology.Thanks to our efforts, the ABC Blockchain Community maintained a positive reputation within the Web3 startup community, and we built strong relationships with industry leaders and stakeholders. Unfortunately, we had to pause our community operation in 2020 due to the COVID pandemic, but we remain committed to continuing our efforts to educate and promote blockchain technology in the future.
