Backend Developer for API Optimization
Skills Required
Description
Optimizing backend APIs requires a combination of efficient architecture, precise coding, and performance benchmarking. The Backend Developer will focus on improving API response times, scalability, and overall system reliability using Node.js, Express, and MongoDB.
The goal is to refine existing RESTful endpoints and develop new ones that handle high traffic efficiently while maintaining data integrity. Every API will be tested for latency, scalability, and security before deployment.
Core objectives include:
Reducing API response time through query optimization.
Implementing caching mechanisms for frequently accessed data.
Refactoring routes for better modularity and readability.
Automating performance testing with real-world traffic simulations.
A major part of this role will be working on database performance. The developer will analyze MongoDB collections and indexes to ensure queries execute in milliseconds, not seconds.
Optimizing Express middleware will also play a key part — removing unnecessary processing layers and streamlining request handling logic.
To improve data transfer, the developer will integrate compression and pagination for larger datasets, ensuring efficiency without overloading the client or server.
Ongoing responsibilities:
Managing Docker containers for isolated and reproducible environments.
Creating scalable microservices for specific applic...
