Hi, I’m Yun Chen Lin!I build reliable full-stack applications and efficient developer tools.

Explored Apache Superset as an analytics layer for TSMC’s centralized approval platform, where product managers otherwise relied on processed SQL queries to review approval activity. Evaluated database integration, SSO, role-based and row-level access control, and dashboard capabilities, while documenting findings for continued development after the internship.

Built and deployed a React, Node.js, and Firebase platform for a VEX Robotics event accommodating 36 teams and 200+ participants and staff. The system supported editable registration, scheduling, authentication, and competitor-roster management, with all 36 participating teams completing registration through the platform.

Co-developed the second iteration of a web-based commission calculator that translated interconnected tax, tier, referral, percentage, and flat-rate rules into automated calculations. Extended an inherited codebase with conditional form behavior, clearer validation, redesigned interactions, and PDF export while confirming calculation logic with the client.
