I will develop and fix full stack web apps with typescript and javascript
Chen
About this gig
Need a web app bug fixed or a small feature delivered? I am a full stack developer working with TypeScript and JavaScript, from frontend interfaces to backend APIs.
My public projects include MySekaiStoryteller, a desktop and Android story editor built with TypeScript and Tauri, and a PixiJS v8 Live2D engine.
BASIC: One small, reproducible bug in one existing module or page. Please provide a working project and steps to reproduce it.
STANDARD: One small feature in an existing app, up to one page and one API endpoint.
PREMIUM: A simple app with up to two pages, one data entity and basic CRUD. Authentication and payments are outside this package.
All packages include relevant source files, verification of the agreed behavior, and setup or change notes. Revisions cover the agreed scope; new features require a separate quote.
Please message me before ordering with your requirements, stack, files and expected result. Hosting, paid services, complex migrations and full commercial products require a custom quote.
