About
Hi!👋 I'm Chris Hung,
Front-end → full-stack engineer who builds data-heavy, user-facing web apps. React/Next.js (App Router, SSR/ISR, TypeScript) on the front; Node (Hono), REST/RPC, and PostgreSQL + Drizzle on the back. I ship with CI/CD, E2E tests, and observability, and I make calls with LCP, P95, bundle size, error rate, and cost. I’ve shipped across education, commerce/content, operations/logistics, and geospatial. I thrive in 0→1 builds and in refactors that raise performance and maintainability. I work tightly with design and backend/ML teams and translate complex ideas for non-technical stakeholders. Looking for front-end or full-stack roles at the intersection of visualization, performance, and API/DB design. Based in Taipei.
