Backend Developer for API Integrations
Skills Required
Description
Integrating APIs efficiently forms the backbone of scalable software systems. This project focuses on building secure and optimized backend services that connect multiple applications and handle large data flows reliably. The Backend Developer will take responsibility for designing and maintaining API-driven architecture using Node.js and Express, ensuring fast response times and stable performance across all environments.
The ideal candidate will create structured and well-documented REST APIs that seamlessly integrate with frontend and third-party systems. This includes defining endpoints, implementing authentication mechanisms, and ensuring robust error handling for all data operations. A clear understanding of HTTP protocols, middleware configuration, and asynchronous programming will be essential to deliver efficient results.
Database management is a core part of this role. You’ll work extensively with PostgreSQL, designing schemas, optimizing queries, and maintaining relationships between datasets. Indexing, query tuning, and migration handling will all be key to ensuring system performance remains consistent even as data scales.
Security is a top priority. The developer must implement token-based authentication (JWT or OAuth) and follow best practices for handling user sessions, password encryption, and sensitive data protection. Understanding API security vulnerabilities such as injection attacks, CORS misconfigurations, and rate limiting wi...
