Backend & Platform Engineer / Tainan, Taiwan

Reliability signals before the incident.

I read engineering systems as operational surfaces: contracts, event streams, deployment paths, maintenance habits, and the evidence trail a team can use when pressure arrives.

CCTS, APSEC 2022, TCSE award

OSS integrations, localization, docs

Incident memory

Timeline as operational context.

Every system claim is mapped to where it was learned: research, delivery, internal systems, or living infrastructure.

Internal systems under real business constraints

Ming-Chyuan MIS work creates a long-running baseline: software has to survive legacy systems, manufacturing workflows, and maintenance pressure.

Computer science training at NTOU

B.S. and M.S. work converge on service-oriented architecture, event-driven testing, and maintainability under research constraints.

CCTS and SOSELab research line

CCTS turns consumer-driven contracts, event logs, and state models into a composite test service for event-driven microservices.

ITRI PDAS delivery work

Personal-data authorization and valuation/payment platform work spans logging, payment, blockchain, CI/CD, fintech integration, and AKS delivery.

Home-lab and public collaboration

Self-hosted systems, server automation, and public PRs keep the engineering habit grounded in operational feedback.

Briefings

Short essays for teams evaluating fit.

Contracts Are Only Useful When They Meet Runtime Evidence

CCTS matters because it connects contract definitions with event-log paths and state-model assertions, closing the gap between interface agreement and actual behavior.

Delivery / 5 min read

Delivery Documentation Is Architecture Work

The PDAS work shows why deployment, CI/CD notes, infrastructure constraints, and customer handoff are not afterthoughts; they decide whether the system can be trusted.

A Home-lab Keeps Platform Taste Honest

Running storage, DNS, monitoring, media, albums, and automation changes how architecture feels: failures become personal, and clarity becomes operational leverage.

Collaboration / 4 min read

Small Open-source PRs Show How Someone Enters a Codebase

Integration, localization, and documentation fixes reveal a practical collaboration style: learn the boundary, reduce friction, and leave a clearer path behind.

Portfolio intelligence layer

Research evidence, APIs, charts, and blog-grade operating notes.

This shared layer turns every variant into a richer portfolio surface: API endpoints, command search, live GitHub enrichment, article cards, timeline context, and machine-readable data.

Live enhancement

GitHub public API slot

The client can fetch current public profile data without requiring secrets. If the network fails, static evidence remains complete.
