About
Hi, I’m Jui-Sheng Hsu, a full-stack engineer based in Taichung, Taiwan. I specialize in building scalable web applications and serverless infrastructure, with about five years of hands-on experience delivering production-ready products.
I’m focused on React, TypeScript, and AWS serverless architectures (Lambda, API Gateway, DynamoDB, CloudFront). I designed and launched a serverless SaaS platform using AWS CDK that enables multiple independent products to be deployed rapidly with near-zero infrastructure cost. I implemented cross-product authentication (SSO) with Cognito, integrated Polar Payments, and shipped multi-language support and PWA capabilities across platforms.
