Experience

Jan 2026 — now

Software engineer intern, ERP & AI integration

Current

InstaVoxel · Taiwan

Designed and shipped an end-to-end order-creation module as the sole engineer — data model, form flow, validation — cutting order creation from several hours to 10–15 minutes.
Built a Pydantic AI retrieval agent orchestrating vector search, direct database read/write and Asana order lookups, with type-safe structured outputs.
Structured a domain-specific knowledge base around the workflows the company already ran, rather than the ones a diagram wished it ran.

Co-founder

KindReach · Taiwan

Co-founded a sports-tech startup for amateur sports communities — product direction, technical architecture, team execution.
Built and deployed the badminton automatic editing system alone, from data pipeline to shipped product.
Co-developed the sports meetup platform to 800+ active users, balancing features against infrastructure and CI/CD.

Chairman, football club

Feng Chia University · Taichung

Budget, compliance paperwork, match-day logistics and member recruitment. Included because running a club taught me more about requirements gathering than any course did.

Portfolio

Paper AnchorPersonal project · Jun 2026 — now
A self-hosted, citation-anchored reader for academic papers: every LLM answer links back to the exact highlighted passage in the source PDF.
OrthoshotPersonal project · May 2026 — now
Open a STEP file in the browser, read off its dimensions and weight, and export ten standard views in one click. No backend — the geometry never leaves the machine it was dropped onto.
Enterprise RAG AssistantPersonal project · May 2026 — now
A RAG backend for enterprise knowledge bases: tenant isolation enforced in SQL, the tenant derived from the API key alone, and a lexical retrieval arm rebuilt on character trigrams for Chinese.
Workflow ERP systemInstaVoxel · Jan 2026 — now
One order-creation pipeline replacing a fragmented, multi-step manual workflow — requirements to production, as the only engineer on the module.
Badminton automatic editingKindReach · May 2025 — Apr 2026
A lightweight, mobile-oriented system that edits badminton footage by itself: YOLO tracks the shuttlecock and keeps only the rallies.
Sports meetup platformKindReach · Feb 2025 — Apr 2026
Event organising for amateur sports communities — the product that found the users, then had to keep them.
Specific vehicle recognitionKindReach · Feb — Jun 2025
Five hundred images hand-labelled, then a YOLOv11s fine-tuned by transfer learning until the numbers held at every resolution.
Commit summarisation toolCapstone, Feng Chia University · 2025
Reads your starred GitHub repositories and has an LLM explain what actually changed between commits.
