  • Architect and implement distributed data models using Cosmos DB (Core SQL or Mongo API) and MongoDB to support large-scale, high-throughput applications.
  • Define partitioning, indexing, and data distribution strategies for optimal scalability and performance.
• Performance Engineering:
  • Conduct deep query analysis, index optimization, and RU/cost optimization in Cosmos DB.
  • Implement profiling, query tuning, and aggregation optimization in MongoDB.
• Automation & Operations:
  • Build automation scripts (Python, PowerShell, Bash) for deployment, monitoring, and scaling.
  • Integrate database monitoring and alerting using Azure Monitor, MongoDB Ops Manager, or similar tools.
• Data Lifecycle Management:
