• AI Integration: Work extensively with LLM APIs (Google Gemini, Azure OpenAI) and cloud vision services for content analysis and processing
• Data Pipeline Development: Build and maintain sophisticated data extraction, normalization, and analysis pipelines
• External API Integration: Integrate with and manage multiple third-party APIs and web services for data acquisition
• Cloud Infrastructure: Deploy and manage containerized applications in Azure cloud environments using Docker
• Performance Optimization: Implement caching strategies, quota management, and performance monitoring systems
• System Architecture: Contribute to architectural decisions for scalable, maintainable backend services

- Real-time monitoring and quota management systems

- Comprehensive testing and security frameworks

Am I a Good Fit?

Consider these questions:

What's the difference between anyio, trio, and asyncio?

What does the await keyword do in Python?

What is a Kubernetes pod, and how is it different from a container?

If you have solid answers for these—without reference to documentation—then we should chat!
