Introduction
About - Yihan Zhao
Full-stack engineer with end-to-end ownership — from understanding business requirements to shipping production-ready apps. I build scalable web and mobile applications across UI, APIs, data, and infrastructure.
I ask “why” before I write code. Every feature starts with understanding the problem, the user, and the business outcome — then I design systems that deliver measurable results.
- Full-stack ownership: spec → design → implementation → deployment
- Product-minded: I translate business goals into technical decisions
- Quality-first: clean code, accessibility (WCAG), automated CI/CD
