Personal portraitSan Francisco

Min-Huan Tsai

I like systems work where performance, correctness, and actual deployment matter: pipeline latency, model cost, search quality, and user-facing reliability.

What I build

I build data products and software that hold up in production.

NCKU EE-CSIE master's student with internship experience at TSMC, GoFreight, and QuickClick. My work spans data engineering, backend systems, and applied AI, with four international publications, three internships, and a TSMC hackathon win.

Experience

Data Engineer Intern, RD

GoFreight

Sep 2025 - Mar 2026

Built production dbt models and analytics layers on Snowflake, improving both pipeline reliability and downstream decision speed.

Architected and deployed 10+ dbt models for downstream BI and reporting.

Optimized 3 core fact models and reduced build time by 60%.

Designed 4 Metabase dashboards that turned operational data into usable business views.

Software Engineer Intern, IT

TSMC

Jul 2025 - Aug 2025

Worked on document intelligence and search workflows, combining Java backend systems with LLaMA-based processing.

Developed an auto-summarization, tagging, and org-ID pipeline for 100K documents.

Designed a Trie-based matcher that ran 70% faster than the prior regex approach.

Cut LLaMA token usage by 95% through pre-extraction and filtering logic.

Software Engineer Intern, RD

QuickClick

Jun 2022 - Jan 2023

Shipped backend product features in a user-facing fintech environment with production traffic and strict correctness expectations.

Built a cashflow verification module serving 10,000+ users.

Delivered rebate and coupon modules with Node.js for large-scale user operations.
