Full-Stack Developer (React, Node.js, TypeScript) for SaaS Bug Fixes & Stripe Integration

We’re looking for an experienced Full-Stack Developer to help with a few final improvements to an existing SaaS web application. The application is already developed and mostly functional. We need someone to review a few parts of the codebase, fix minor issues, and help finalize some technical details before launch. Main Tasks - Fix a few frontend and backend bugs in React and Node.js. - Review and improve existing TypeScript code. - Check and finalize the existing Stripe payment integration. - Make minor API and database improvements if needed. - Review deployment configuration and basic AWS setup. - Perform final testing to ensure everything works correctly. Required Skills - React.js, Node.js, JavaScript, and TypeScript. - Stripe API and payment integration. - REST APIs and SQL databases. - Basic AWS, Docker, and deployment experience. - Experience maintaining existing SaaS applications. Project Details This is a small, short-term project focused on improving an existing application, not building anything from scratch. Most of the functionality is already implemented. We expect the remaining work to be relatively straightforward for an experienced developer. There may be opportunities for additional development and maintenance work in the future.
