Node.js Backend Developer for Quick API & Backend Fixes

We’re looking for a Node.js developer to help us with some quick fixes and improvements on our existing web application. The backend is built with Node.js, Express.js, PostgreSQL, and Redis. We currently have a few issues with API responses, payment webhook handling, and some backend logic that needs to be cleaned up. We’re looking for someone who is comfortable working with an existing codebase and can quickly identify and fix issues without affecting the current functionality. The work includes fixing several REST API endpoints, improving error handling, resolving a payment webhook issue, and making a few small PostgreSQL query improvements. Experience with Node.js, JavaScript/TypeScript, Express.js, REST APIs, PostgreSQL, Redis, and third-party API integrations is important. If everything goes well, we may also need help with additional backend functionality in the future.
