• Implement request validation, centralized error handling, consistent API responses and API documentation using Swagger/OpenAPI.
• Develop secure authentication and authorization mechanisms, including JWT, RBAC and permission-based access control.
• Implement caching strategies using Redis and asynchronous processing using messaging queues and background jobs.
• Integrate third-party APIs and external systems, handling authentication, rate limits, retries, timeouts and failures.
• Optimize API performance, database access, resource utilization and application scalability.
• Containerize applications using Docker and deploy backend services using Microsoft Azure.
• Implement structured logging, monitoring, distributed tracing, health checks and other observability practices.
• Write automated tests, participate in code reviews, troubleshoot production issues and maintain technical documentation.
• Collaborate with frontend engineers and other stakeholders to define API contracts and deliver end-to-end features.

• Strong proficiency in Node.js, TypeScript and modern JavaScript.
• Hands-on experience with NestJS, including modules, dependency injection, guards, interceptors, pipes and exception filters.
• Strong understanding of REST API design, asynchronous programming, modular architecture, SOLID principles and clean code practices.
• Hands-on experience with PostgreSQL, Prisma ORM, schema design, migrations, transactions, indexing and query optimization.
• Experience with Redis for caching, TTL management, cache invalidation and performance optimization.
• Understanding of database consistency, connection pooling and efficient data-access patterns.
• Experience implementing DTOs, request validation, centralized error handling and consistent API contracts.
• Familiarity with class-validator, class-transformer and Swagger/OpenAPI.
• Understanding of authentication, authorization, JWT, OAuth 2.0, RBAC, API security, rate limiting and secure secrets management.
• Experience handling pagination, filtering, API versioning, retries and backward compatibility.
• Experience with Microsoft Azure or equivalent cloud platforms, with the ability to work with Azure services in production.
• Familiarity with Azure App Service, Azure Container Apps, Azure Database for PostgreSQL, Azure Service Bus, Azure Key Vault and Azure Cache for Redis.
• Understanding of messaging queues, background jobs, event-driven architecture, retries and failure recovery.
• Experience integrating third-party APIs and handling asynchronous workflows.
• Understanding of Node.js performance, concurrency, caching, database optimization and scalability.
• Familiarity with structured logging, metrics, distributed tracing, health checks and monitoring tools such as Application Insights or OpenTelemetry.
• Hands-on experience with Docker, Git, CI/CD and automated testing using Jest or equivalent tools.
• Experience writing unit and integration tests and debugging application issues across development and production environments.

Nice to have

• Experience with microservices, event-driven architecture, domain-driven design and clean architecture.
• Familiarity with advanced messaging patterns, idempotency, dead-letter queues and distributed system reliability.
