Backend & Platform Engineer · Taipei, Taiwan
Building backend systems that stay stable, maintainable, and deployable as complexity grows.
"It's not a bug, it's a feature."
About
I focus on what happens after you ship. Will the person who inherits this codebase understand what I was thinking? Will the ops team trust it at 3am? That mindset shapes everything I build.
My research and work have converged on one theme: making distributed systems predictable. At NTOU I designed a testing framework for event-driven microservices. In industry I build platform infrastructure that reduces delivery friction. The goal is the same either way — remove surprise from production.
I'm active in Taiwan's civic tech community through g0v.social, and I run a home-lab where every service is my own code. If something breaks at 3am, I'm the one who knows why.

Introduces CCTS (Composite Contract Testing Service), a testing tool for event-driven microservices. Combines consumer-driven contract testing with event-driven state models to record state transitions of event exchange between services and automatically retrieve possible transition paths.

Uses Citizen Digital Certificate, digital signature, and blockchain to establish an authorization system (PDAS) for digital personal data. Enables safe, undeniable, and tamper-proof data authorization contracts that address legality, security, and multi-user authorization.

Selected Work
Composite Contract Testing Service — the research system behind my APSEC 2022 paper. Combines Pact consumer-driven contracts, event-log sequence validation, and SAGA-style state assertions into one verification framework.
JavaFull lifecycle delivery — backend logic, workflow design, deployment. My most complete end-to-end ship. Demonstrates what ownership looks like when there is no one else to hand things off to.
Python · DockerDocker-based home-lab infrastructure. Real services I depend on daily — not a portfolio piece. When I say 'deployment-oriented,' I mean I live with the consequences.
ShellServer thermal automation. Wrote it once, forgot about it. My server room is quiet. That's what good automation looks like.
TypeScriptAI-assisted prototyping. Using AI as a practical engineering tool, not a buzzword. Fast iteration with production-quality thinking underneath.
Experience
Designed and implemented CCTS — a contract-testing framework for event-driven microservice systems. Published at IEEE APSEC 2022 and received the 2022 Best Chinese Paper Award at TCSE.
Worked on the Personal Data Authorization System — digital-signature-based, blockchain-anchored authorization contracts for personal data. Joint research with Industrial Technology Research Institute (ITRI). Published at IEEE ICS 2020 and two domestic conferences.
Contribute across personal infrastructure, team projects, and public OSS workflows. Pattern: cleanup, integration, correctness.
