- Lead the design and development of secure REST APIs and microservice in Python.
- Architect and integrate GenAI workflows using LlamaIndex, LangChain or similar frameworks.
- Implement real-time streaming using Server-Sent Events (SSE), event-driven patterns, and messaging systems.
- Optimize and maintain database architectures (SQL/NoSQL) for performance and scalability.
- Define and enforce security best practices, authentication, and authorization (OAuth2, JWT).
- Establish standards for structured logging, monitoring, and distributed tracing.
- Drive cloud-native deployments and ensure systems scale seamlessly.
- Mentor mid-level engineers, lead architecture discussions, and set engineering standards.
- Collaborate across product, data, and infrastructure teams to align backend capabilities with business needs.
