● Backend Development: Build, scale, and maintain backend services and microservices using technologies such as Node.js, Express.js , and NestJS (experience with Go, Python, or Java is a plus). 

● System Design & Architecture: Design and implement reliable and maintainable backend architectures. Apply principles of modular architecture, event-driven systems , and microservices where appropriate. 

● API Development: Develop and maintain RESTful APIs and GraphQL endpoints for efficient frontend-backend communication, with a focus on performance, versioning, and security. 

● Database Management: Design and optimize schemas for relational databases like PostgreSQL , MySQL , as well as NoSQL databases like MongoDB , Redis , or DynamoDB . 

● Performance Optimization: Identify and resolve bottlenecks in APIs, queries, and backend logic. Use tools and strategies for load handling, caching (e.g., Redis), and horizontal scaling. 

● Code Quality & Best Practices: Write clean, testable, and maintainable code. Participate in code reviews and promote engineering best practices. 

● Testing & Debugging: Write unit and integration tests (e.g., using Jest , Mocha ) and debug production issues efficiently. 

● CI/CD & DevOps Collaboration: Work with the DevOps team to integrate backend services into CI/CD pipelines and automate deployments. 

● Collaboration: Work cross-functionally with frontend engineers, designers, product managers, QA, and DevOps to ship features in a collaborative agile environment.
