I'm Guan-Ting Su, a Senior Frontend Engineer with 5 years of experience.
Started from Physics & Astronomy, fell in love with frontend development since 2020.
Now specializing in Web3/DeFi applications, Design Systems, and bridging design with engineering.
I care about scalable architecture, performance, and making complex things user-friendly.

Multi-strategy DeFi asset management interface backed by Pantera Capital. Architected a unified frontend supporting 3 vault types (Managed, Permissionless, Portfolio) across EVM and CairoVM chains, with a deposit/withdrawal abstraction layer that enables seamless multi-asset flows.

On-chain leverage trading interface on Sei Network (project in wind-down; core trading UI no longer publicly accessible). Built real-time price feeds, position lifecycle management, dynamic margin health visualization, and gamified reward campaigns to drive user retention.

Open-source React Native date picker with 60+ GitHub stars and hundreds of weekly downloads. Actively maintained with community issue resolution and feature development.

Cross-platform travel budgeting app with ~400 monthly active users. Features currency conversion, shopping cart, and expense tracking. Recently launched a Pro plan as monetization. Collaborated closely with a UI/UX designer on user flow optimization.

Redesigned a legacy HTML site using Vite + React for Taiwan's astronomy research community. Built a CMS (React + Flask + PostgreSQL) that reduced content update time from ~10 minutes to 30 seconds. Currently offline for maintenance by subsequent maintainers; source and design on GitHub / Behance.

Contributed page layout design and built the static frontend from design specs. Architected a config-driven content structure so the non-technical owner can update all portfolio content by editing a single TypeScript config file.
