2. Cloud-Native AI Development

  • Build multi-cloud GenAI platforms (Azure OpenAI, GCP Vertex AI, AWS Bedrock) with unified MLOps

  • Implement enterprise-grade security: VPC peering, private endpoints, data residency compliance

3. Innovation & Strategy

  • Pioneer GenAI use cases: agentic workflows, synthetic data generation, real-time fine-tuning

  • Establish AI governance frameworks: model cards, drift monitoring, red-teaming protocols

4. Cross-Functional Impact
