簡介
近 10 年後端與平台工程經驗，擅長身分認證、多租戶、核心業務服務與雲端基礎設施；熟悉 0→1 驗證、1→10 穩定化與 10→100 維運。2025 年起把同一套工程紀律延伸到 LLM / Agent 產品化（閘道、治理、計費與可靠性）——目前同時擔任響雨互動娛樂 Tech Lead，並以外包形式承接 ViewSonic AI 產品線。
近期業務：平台後端（自建 OIDC / Federation、帳戶與組織、事件驅動與 monorepo 治理、全站登入類 P0 on-call）；產品重構與商業化（VR 教育核心 .NET → NestJS，訂閱 / credit / AI 教案）；AI 系統工程（AI Gateway、可治理銷售知識系統、教育生成平台）。
有 Tech Lead 與團隊 Mentor 經驗：對接 PM / 業務 / 教育團隊、收斂需求與優先級、導入工程標準與 code review；能獨立交付全端。AWS 與 GCP 皆有深度實戰（亦有 Azure 部署經驗），習慣在架構、成本與可靠度之間做取捨。專長：Backend / Architecture；近年延伸至 LLM 平台與 Agent 工作流落地。

Summary
Nearly 10 years in backend and platform engineering, strong in identity, multi-tenancy, core business services, and cloud infrastructure — from 0→1 validation through 1→10 hardening to 10→100 operations. Since 2025, applying the same discipline to shipping LLM / Agent products (gateways, governance, billing, reliability) — currently Tech Lead at Hibikiame while contracting on ViewSonic's AI product line.
Recent work: platform backend (in-house OIDC / Federation, account & org services, event-driven design, monorepo governance, P0 login on-call); product re-architecture & monetization (VR education .NET → NestJS; subscriptions / credit / AI lesson plans); AI systems engineering (AI Gateway, governed sales knowledge, education generation).
Tech Lead and mentor experience: partnered with PM / business / education teams, clarified priorities and compliance, established engineering standards and review practices; can ship full-stack when needed. Deep hands-on experience with AWS and GCP (plus Azure deployments). Strengths: Backend / Architecture; recently extended into LLM platforms and agent workflows in production.
Experience
Tech Lead across product lines — architecture and delivery ownership; technical liaison to education (requirements, compliance, prioritization); AI-assisted code review for consistent quality.
VR Education Platform (core backend rewrite)
Led rewrite of legacy ASP.NET + MagicOnion gRPC into NestJS domain services; Unity client migration gRPC → REST.
- Platform: multi-tenant RBAC + subscription entitlements; feature flags; credit / learning-points ledger (incentive currency isolated from billable credit; saga redemption)
- AI productization: AI Provider abstraction; curriculum RAG (pgvector); AI lesson-plan assistant (structured plans bound to courses with credit billing; 3D recs from real inventory)
- Data & infra: 70+ entities MySQL → PostgreSQL; OpenTofu on GCP; audit → BigQuery; Cloud Run + committed-use, ~20% lower cloud cost
MDM Device Platform
Device console and agent for education fleets (Meta Quest / Pico / HTC Vive / Android) — lifecycle management.
- Enrollment, policy push, APK versioning & signatures; MQTT (QoS=1) command dispatch with full lifecycle tracking
- Health monitoring and dual-mode enrollment
Platform Hub, ACG Commerce & Gamer Link Site
- Turborepo monorepo: SSO hub reusing prior in-house OIDC experience (silent re-auth, federation, dual-channel reset); modular accounts; SmilePay + ibon; Python risk service
- Gamer Link Site 0→1: custom slugs, platform detection, en/zh-TW; ownership verification (DNS / well-known / email) + Verified badge; Cloudflare Workers SEO
Backend / platform lens on brand AI products: unified gateway, knowledge governance, generation workflows, and internal automation — delivering operable services with internal stakeholders.
Sales Knowledge System (Governed Knowledge)
Rebuilt the sales assistant as a governed, anti-hallucination platform — spec values from deterministic queries, never LLM generation; every claim must be citable.
- Facts (Markdown-KV + DuckDB) / document evidence / narrative (mandatory cites + human review); soft schema without DB migrations
- Online Q&A decoupled from back-office authoring (Claude Agent SDK); read-only MCP knowledge interface
- Citation checks, golden-set, link health; 412/412 product-spec zero-omission; upstream pipelines via landing contract
AI Gateway, Education Generation & HR Automation
- Go AI Gateway: dynamic registries (timeout / retry / rate limit / health); four-state async tasks + Redis / webhooks; two-layer cache; ECS blue-green
- Langflow: enterprise generation with 20+ flows; multimodal components and agent orchestration (SSE / webhooks); ECR → EKS
- HR automation: Claude Agent SDK — JD parsing → candidate extraction → weighted shortlist; policy Q&A with citations
Owned ViewBoard / myViewBoard membership and organization core; mentored a 4+ engineer backend team; led PR review and written design decisions (RFC / ARD / SA).
Identity & Account Platform (greenfield)
- In-house OIDC Provider as unified login hub; 6 enterprise / social / education federation strategies
- MFA, CSP/CORS, forced SSO; account lifecycle (incl. bulk); org invite / roles / domain + wildcard
- Event-driven CDC (
account.created, etc.)
Platform Libraries, Architecture & Reliability
- Reusable webhook, Event Store, CQRS, multi-vendor SSO strategy libraries
- CQRS + Event Sourcing and cross-team DDD; led migration of 6 core services into a monorepo with no business interruption
- Terraform + Terragrunt multi-env; operated AWS / GCP; 24/7 on-call for P0 incidents (site-wide login, multi-service disruption, domain)
Team
- Mentored backend engineers; engineering standards and tech sharing; written ADRs to reduce cross-team friction
Tech Lead: requirements, cross-team and vendor negotiation, incidents, hiring interviews; negotiated payment fees ~20% below market.
- Creator commission platform: Laravel 0→1, then led NestJS + Next.js monorepo refactor (DDD); multi-processor payments, realtime chat, notifications, recommendations, moderation, search/SEO
- Shared platform: SMS / OTP extracted to internal API; VPN-isolated test environments
- Web3 (side line): ERC-721, Nuxt3 + Ethers, rarity / image pipeline
- Built the v1 learning site on a Laravel monolith in ~8 sprints; design patterns for complex course modules
- Integrated multi-type third-party streaming (audio / video / live); maintained a WordPress landing page
- Bridged WooCommerce orders into the new system via Express produce API → RabbitMQ
- Frontend in Vue 2; Azure deployment with Docker Compose for development
- Achievement system (from scratch): library to interface with ML Team data and normalize formats; client endpoints and requirement-driven APIs; legacy refactors
- Internal systems & infra: CMS / CRM; Terraform automated deployment and IaC; data-layer tuning and failover under load
- Top-30 traffic CMS: hybrid-level RBAC, content management UI, AI-generated articles produced to Kafka, reporting + GA with D3.js
- 0→1 projects: built and operated multiple small content sites with designers; cloneable monolith site template; legacy maintenance
