• Lead Architecture Review Boards and design authority discussions, reviewing and approving technical designs.
• Develop reference architectures, solution blueprints, and design patterns across OCI services.
• Provide architecture governance and technical assurance across delivery teams, including review of non-functional requirements.
• Architect OCI landing zones and multitenancy models, including compartment hierarchies, tagging, IAM policies, and governance controls.
• Design hub-and-spoke VCN architectures, DRG transit routing, FastConnect and IPSec hybrid connectivity, and multi-region peering.
• Define security architectures using Cloud Guard, Security Zones, Vault, WAF, Bastion, and network segmentation.
• Design data platforms using services such as Autonomous Database, Exadata Cloud Service, MySQL HeatWave, OCI Data Flow, and OCI Streaming.
• Architect monitoring and operational frameworks using OCI Monitoring, Logging Analytics, APM, Management Agent, and integrations with tools such as Datadog, Splunk, or Grafana.
• Lead architecture workstreams for large-scale migrations, including migration waves, workload dependencies, sequencing, and appropriate migration patterns.
• Define database migration approaches using OCI Database Migration Service, GoldenGate, Zero Downtime Migration, and Data Pump.
• Plan application modernization through containerization on OKE, serverless services such as OCI Functions, or platform re-architecture.
• Design Kubernetes platforms on OKE, including cluster topology, namespace governance, ingress, service mesh, and multicluster approaches.
• Architect CI/CD platforms using OCI DevOps, GitLab, GitHub Actions, ArgoCD, and policy-as-code tools.
• Define Infrastructure as Code standards for Terraform modules, state management, provider versioning, pipelines, and OCI Resource Manager.
• Design event-driven and microservices architectures using OCI Streaming, OCI Queue, OCI Functions, and API Gateway.
• Architect OCI environments for Oracle E-Business Suite, PeopleSoft, JD Edwards, Fusion Middleware, and SOA Suite.
• Design Oracle Database architectures using RAC, Data Guard, Autonomous Database, and Exadata Cloud Service, with high availability and disaster recovery aligned to Oracle Maximum Availability Architecture.
• Define integration approaches between Oracle Cloud Applications and OCI-hosted or legacy workloads.
• Design cross-platform integrations using Oracle Integration Cloud and API Gateway.
• Establish cost governance, showback or chargeback approaches, and budget alerts using OCI Cost Analysis and Budgets.
• Review workload placement, right-sizing, and capacity options to improve performance and cost efficiency.
• Define and track cloud efficiency measures, such as utilization, cost per transaction, and avoidable spend.
• Present architecture decisions, risks, and recommendations to senior technology and business stakeholders.
• Contribute to proposals, RFP responses, estimates, and technical presentations.
• Provide architectural oversight to delivery teams and resolve complex design issues.
• Mentor senior cloud engineers and support technical capability development.

Qualifications and Experience
