I’m Zhiqin Qiang, a computing undergraduate from Nanyang Technological University who enjoys building AI-powered products and full-stack systems. I’ve worked on backend services with FastAPI, Redis, and SQLite, and I also built a decentralized auction DApp on Ethereum using Solidity and a Next.js frontend. I care about reliability and quality—whether it’s writing tests for cache fallbacks, running integration testing in QA, or evaluating AI-generated code to help improve model outputs. I’m especially interested in AI engineering, web development, and blockchain, and I like turning complex ideas into working software.…I’m Zhiqin Qiang, a computing undergraduate from Nanyang Technological University who enjoys building AI-powered products and full-stack systems.
