I will build, fix, or integrate Express.JS and Node.JS REST apis and webhooks

Stop struggling with failing API callbacks, unhandled webhook payloads, or backend server errors. I deliver clean, production-ready Express.js and Node.js code designed to keep your business applications running smoothly and reliably without downtime.

What I build and fix for your backend:

1. Quick API and Webhook Fixes: Fast troubleshooting for broken endpoints, payload parsing issues, CORS errors, and failing signature verifications.
2. Custom Webhook Handlers: Reliable webhook endpoint creation with built-in event verification, dynamic database synchronization, automated retry loops, and error logging.
3. RESTful API Endpoints: Lightweight Node.js and Express routes tailored to connect your frontend application, mobile app, or third-party external services cleanly.

How the development process works:

1. Order and Share Access: You provide repository access on GitHub along with any test or staging API keys required to test the routes locally.
2. Isolated Development: I develop and test the required features or bug fixes on a clean, dedicated Git feature branch to protect your existing codebase.
3. Verification and Delivery: I test endpoints end-to-end and submit a clean Pull Request complete with inline code comments and documentation.

All backend code follows clean async/await patterns, robust error handling, and standard security middleware practices.

Tailored Service and Communication: This offer covers complete planning, execution, and delivery based on your agreed project scope, prioritizing clear communication and quick turnarounds.
