Operating thesis
The through-line is reliability, but the habit is clarity.
I am a software engineer and service developer with an M.S. and B.S. in Computer Science and Engineering from National Taiwan Ocean University. My strongest through-line is reliability: service design, event flow validation, deployment, and operations.
At SOSELAB, my thesis work became CCTS, a Composite Contract Testing Service for event-driven microservices. It combines Pact contracts, runtime event logs, and state-model validation so testers can detect missing transitions and execution failures instead of trusting happy-path demos.
At ITRI, I worked on the Personal Data Authorization System and a personal-data valuation/payment platform. The work touched logging, payment, blockchain, third-party fintech, CI/CD, infrastructure, and delivery on Azure Kubernetes Service.
Evidence routes
Four paths describe the same engineering personality.
Event-driven systems need observable contracts.
CCTS connects Pact contracts, runtime event logs, RabbitMQ, MongoDB, and state-model assertions so execution paths can be checked instead of guessed.
APSEC 2022 / TCSE Best Chinese PaperProduction pressure shaped the platform instinct.
PDAS and the valuation/payment platform pushed work across logging, payment, blockchain, fintech integration, CI/CD, infrastructure, and AKS delivery.
ITRI / PDAS-team / ICS 2020Home-lab work keeps the architecture honest.
Thirty-plus self-hosted services make reliability personal: storage, DNS, monitoring, media, albums, automation, and server control all have consequences.
HomeLab / iDRAC / internal systemsPublic work trends toward integration and correctness.
The open-source trail is not random volume. It is a pattern of adding missing integrations, improving localization, and fixing inaccurate docs.

Each selected project shows a different pressure: research validation, complete ownership, home-lab operations, or server automation.

CCTS
Composite Contract Testing Service — my NTOU thesis system and APSEC 2022 paper implementation. It combines Pact contracts, event-log sequence validation, and state-model checks to catch missing transitions and execution failures in event-driven microservices.
HideReplier
Anonymous Discord reply bot built for the NTOU CS Discord context. It grew from a course project into a containerized service with CI/CD, Docker Hub image flow, and Fly.io deployment.
myServices
Home-lab service configuration and operations notes. The broader environment runs 30+ services across storage, DNS, monitoring, media, albums, and home automation with VM/container integration.
iDRACFanSpeedControl
Dell PowerEdge fan control through iDRAC/IPMI with Docker deployment, NVMe/GPU temperature inputs, configurable thresholds, and a recent README/code audit around fail-safe behavior.
Research trail
The academic line reinforces the system line.
SOSELab studies software engineering techniques and service-oriented computing applications, with research directions that include microservice testing, monitoring, retrieval/search, service-oriented architecture, and chatbot application architecture.

Testing for Event-Driven Microservices Based on Consumer-Driven Contracts and State Models
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.

Technical surface
Broad stack, narrow engineering taste.
Tools change by context, but the patterns stay consistent: clear contracts, explicit data flow, deployable systems, and maintainable handoffs.
