Hi, I’m Jess Wang, a technology leader and backend architect with a passion for building scalable systems, distributed architectures, and Web3-enabled platforms. I’ve led performance-focused engineering teams, shipped high-throughput trading and DeFi features, and designed robust data flows, microservices, and CI/CD pipelines to support rapid growth and liquidity. I enjoy mentoring engineers, turning ambitious ideas into reliable products, and collaborating closely with product and business teams to drive measurable outcomes. In my career, I’ve balanced hands-on coding with strategic leadership—designing API-first services, optimizing core engines, and delivering features that boost revenue and user engagement. I thrive in fast-paced environments where clean architecture, clear documentation, and strong teamwork matter as much as speed to market.
