Building Backend Services and API Reliability

At Corebit Tech, I worked on backend services using Node.js, Express.js, MongoDB, Mongoose, and third-party APIs.

The backend needed reliable APIs, improved database structures, and better integration with external services.

The work involved existing systems, migration from MySQL to MongoDB, and the need to maintain API reliability.

I developed RESTful APIs, migrated database structures, optimized query performance with Mongoose, and integrated third-party services.

The main trade-off was balancing migration work with ongoing backend feature delivery.

Improved the reliability and maintainability of backend services by introducing clearer service boundaries, more predictable API behavior, and a stronger foundation for future enhancements. The resulting architecture reduced the effort required to extend functionality and troubleshoot production issues.

I learned the importance of data modeling, API contracts, and backend reliability early in the development lifecycle.
