Backend Engineer in Taiwan.

I build systems people can rely on.

Backend-focused — performance, clarity, and turning new tech into things that actually ship.

Frontend

I craft seamless interfaces for real user intent.

Scalable state architecture, modular components, and intuitive interactions.

Backend

I design resilient systems that stay calm under load.

Domain-driven design, high-availability APIs, and complex data relations.

DevOps

I build automated paths from code to production.

CI/CD, containerized environments, and cloud workflows with fewer sharp edges.
