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.
APSEC 2022 · TCSE Best Chinese Paper · 8k+ LOC Java · Spring Boot · Docker · Fly.ioHideReplier
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.
Full lifecycle side project · 10 stars Docker · Linux · NAS · MariaDB · SDNmyServices
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.
30+ services · real operating environment Shell · Docker · IPMI · ESXi · NVIDIAiDRACFanSpeedControl
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.
Dell R730XD tested · 10 starsBuild pipeline
A repeatable path from ambiguity to operable software.
Model
Turn flows into contracts, event paths, deployment notes, or testable boundaries.
Build
Ship the smallest durable system that reduces operational uncertainty.
Harden
Document, monitor, and remove friction before complexity compounds.
Material history
The craft came from multiple pressure types.
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.
Shop notes
What the system should leave behind.
Static JSON APIs
Profile, projects, metrics, insights, styles, search, feed, OpenAPI.
all variantsCommand palette
Keyboard-accessible search over headings, insights, projects, and APIs.
all variantsLive GitHub fetch
Client fetches public GitHub profile and falls back gracefully.
progressive enhancementChart layer
Impact bars, timeline, article taxonomy, and role-fit matrices.
all variantsDocumentation pack
Design rationale, technical notes, Mermaid diagrams, branch/deployment instructions.
ten variantsContracts 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.
6 min readDelivery 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.
