• Integrate enterprise systems such as SharePoint, Snowflake, Figma (REST API) etc. on the shared integration gateway.
• Design data models on platform-managed Aurora PostgreSQL, DynamoDB and S3, and work with shared services such as document processing (Textract), vector search and the knowledge graph (Neo4j).
• Ship through the shared CI/CD and Terraform (IaC) pipelines, with Entra ID / Cognito authentication and secure-by-design practices.
• Develop GenAI features using Amazon Bedrock (Claude) through the shared model gateway, including prompt engineering, RAG over the vector store, Bedrock Guardrails, and evaluation and feedback loops.
