SUMMARY
Technical Lead and backend engineer with 6 years of software engineering experience, specializing in turning complex system problems into clear technical decisions and executable delivery plans. Combine hands-on backend engineering with architecture, technical scoping, and cross-functional execution. Currently lead the technical evolution of an existing two-tier CMS platform spanning 5 brand instances and 10 repositories, with a Redis cache tier serving ~40M requests per month. Currently leading the technical assessment and planning for its Strapi v4 -> v5 modernization, including migration strategy, dependency analysis, and evaluation of opportunities to improve cross-repository maintainability. Now extending this approach with AI-native engineering workflows to explore how agents can accelerate analysis, implementation, and verification while keeping high-risk technical decisions under deliberate human control. Seeking hands-on Technical Lead, Staff-track Backend/Platform, and AI-native engineering roles.

WORK & WRITING
Selected write-ups on CMS platform modernization and AI-assisted engineering workflows — in progress. Repo and articles landing here soon.

EXPERIENCE

Layerx Solutions Co., Ltd. — Taipei, Taiwan
Technical Lead, CMS Platform | Oct 2023 – Present
(Progression: Technical Project Manager -> Backend Engineer -> Technical Lead)
- Own the technical evolution of a two-tier CMS platform (Strapi content layer + Redis cache API) across 10 repositories and 5 brand instances, serving ~40M cached requests per month.
- Maintain and evolve the existing Redis cache tier using stale-while-revalidate, distributed-lock request coalescing, and CMS-triggered refresh.
- Lead the technical assessment and planning for a Strapi v4 -> v5 modernization across 10 repositories. Completed an initial 3-5 day proof-of-concept to identify key upgrade constraints and inform migration strategy; implementation approach and detailed scope are still being validated.
- Evaluating a proposed cms-shared package approach to reduce duplicated maintenance across 10 repositories. Reviewing code divergence and abstraction boundaries to determine which logic is genuinely safe and valuable to share before implementation.
- Decomposed the migration into multiple workstreams with a clear set of architecture decisions and critical path. Proactively unblocked three infrastructure dependencies with long lead times (identity-provider config, private package feed, managed MySQL schema/TLS). Co-own Kubernetes deployment configuration with the infrastructure team.
- Audited SSO/OIDC authentication flow across repositories and identified four issues: token exposure via URL, missing ID-token verification, missing state validation, and sensitive data in logs. Drove remediation into a common log-sanitization standard.
- Evaluate where AI-assisted development can safely accelerate delivery and where higher-risk backend changes still require human review.
- Lead day-to-day delivery across 2 project coordinators and 1 junior engineer (technical scoping, architecture, mentoring, and stakeholder coordination).
Stack: Node.js, Strapi, Redis, MySQL, PostgreSQL, Kubernetes, Azure (Entra ID, Artifacts, Database for MySQL), Docker

LL Informatics — Remote, Poland
Ruby on Rails Developer | Feb 2022 – Sep 2023
- Backend developer on a clinical-trial management SaaS for a US customer.
- Built and maintained REST APIs on Rails 6/7; rewrote data-heavy reporting queries in hand-written SQL when ORM plans were inefficient.
- Wrote unit and integration tests (RSpec, Minitest) and integrated Rails APIs with Vue.js + Jest.
Stack: Ruby on Rails 6/7, PostgreSQL, SQL, RSpec, Minitest, Vue.js, Jest

Wistron Corporation — Kaohsiung, Taiwan
Web Developer, Big Data Division | Jan 2021 – Aug 2021
- Helped the data analytics team turn their results into web interfaces for manufacturing case clients.
- Translated ad-hoc data requirements into reusable application features.

Earlier Experience
- Software Project Coordinator, iNet Information Consulting (2020) — Technical contact for a government digital-forensics system.
- Costing Team Supervisor, Pou Chen Group (2015–2019) — Managed team of 10 across China and Vietnam; participated in data migration and validation during legacy ERP transition.
