Design and implement RESTful API endpoints using FastAPI across multiple backend microservices
Build and maintain data models with SQLAlchem, write Alembic database migrations, and optimize PostgreSQL queries
Develop real-time data streaming features using WebSockets and Server-Sent Events (SSE) for live sensor and operational data
Work with analytics data stores for large-scale data retrieval alongside relational databases for transactional data
Implement and maintain distributed task processing pipelines using cache and message brokers
Build and maintain authentication and authorization logic using JWT validation and policy-based access control
Develop data ingestion and transformation services, including CSV parsing, XML processing, and store-and-forward message patterns
Write comprehensive tests with pytest, including async test patterns
Containerize services with Docker, maintain multi-stage build configurations, and support CI/CD pipelines
Integrate with cloud platform services for storage, logging, messaging, and secrets management
