Backend Developer to Optimize API Performance
Skills Required
Description
Improving API performance isn’t just about speed — it’s about stability, scalability, and efficiency. The Backend Developer to Optimize API Performance will focus on fine-tuning backend architecture, reducing response times, and ensuring that all APIs operate smoothly under heavy load. You’ll evaluate existing systems, identify performance bottlenecks, and implement solutions that enhance both speed and reliability without compromising security.
Your work will involve deep optimization using Node.js, Express, and MongoDB, applying best practices for asynchronous programming, efficient query execution, and smart caching. You’ll analyze how APIs interact with databases and front-end systems, ensuring minimal latency and maximum throughput. Monitoring tools, load testing, and performance metrics will guide your iterations as you refine API endpoints for consistency and efficiency.
Scalability will be a key focus. You’ll implement caching strategies, optimize indexing, and ensure APIs are prepared to handle traffic spikes gracefully. Collaboration with front-end developers and DevOps engineers will help maintain a balanced system, where every layer of the stack performs at its peak.
Key Responsibilities:
Analyze and refactor existing API endpoints for improved response times.
Implement caching mechanisms using Redis or in-memory data stores.
Optimize MongoDB queries and indexing for faster read/write operations.
