Strategic Azure Projects

A selection of high-impact cloud transformation initiatives led as a Professional Services Delivery Architect.

TrustBank AI Gateway

Lead Azure Architect (GenAI Security)

The Challenge: The CISO blocked all GenAI adoption due to "Shadow AI" risks (data leakage, lack of auditability). The business needed a secure way to consume GPT-4o for both public customers and internal employees without exposing private data.

Executive Outcomes

  • Security Approved: Passed CISO review via 100% private networking (Private Links) and Zero Trust access.
  • 30% Cost Reduction: Implemented APIM Semantic Caching to reduce backend token usage.
  • Dual-Mode Access: Enabled safe "Public" and "Private" routing on a single gateway.

Architectural Strategy

  • APIM Governance: Centralized all traffic via Azure API Management for rate limiting and logging.
  • Smart Load Balancing: Distributed traffic across PTUs and Pay-As-You-Go models.
  • GenAIOps: Automated "Red Teaming" evaluations in CI/CD pipelines using Prompt Flow.

Strategic Datacenter Modernization

Migration Technical Consultant (Strategic Core)

The Challenge: Legacy on-premises infrastructure was approaching end-of-life, creating significant OpEx drag ($15k/mo waste) and preventing the adoption of modern, scalable AI/Data workloads.

Executive Outcomes

  • 30% TCO Savings: Shifted CapEx to optimized OpEx via Azure Hybrid Benefit and Rightsizing.
  • Zero Downtime: Executed cutover of mission-critical workloads with 100% business continuity.
  • Azure MEG Framework: Migrated 238+ VMs and 60 apps 2 weeks ahead of the projected roadmap.

Architectural Strategy

  • Discovery & Assessment: Led comprehensive portfolio analysis using Azure Migrate to identify dependency maps.
  • Hybrid Connectivity: Designed ExpressRoute circuits for low-latency, secure replication traffic.
  • Landing Zone Design: Built a Hub-Spoke topology to enforce network isolation prior to migration.
  • Expert Frameworks: Implemented Microsoft-grade Wave Planning (T-Minus logic) and comprehensive Pre/Post cutover checklists.

Microsoft CAF: Enterprise-Scale Landing Zone

Principal Architect (Security & Governance)

The Challenge: "ClickOps" provisioning created a 2-week lead time for new environments, stifling developer innovation and introducing severe security/compliance drift.

Strategic Outcomes (CAF)

  • ALZ Democratization: Empowered 20+ app teams with self-service autonomy via guardrails and vending.
  • Platform Separation: Decoupled Identity, Network, and Management from workload subscriptions.
  • 98% Velocity Gain: Reduced environment provisioning time from 2 weeks to 4 hours via ALZ-Bicep.

Key Implementations

  • Subscription Vending: Implemented the ALZ-Accelerator to vend fully-governed subscriptions with built-in networking.
  • Policy-as-Code: Deployed 150+ Azure Policies to enforce data residency and network isolation by default.
  • Zero Trust Fabric: Enforced strict RBAC, PIM, and Private Link isolation for all Platform services.
  • Risk Mitigation: Utilized official review checklists to neutralize ALZ anti-patterns (ClickOps, Single-Sub drift).

SRE & Cost Optimization

Lead Architect (SRE & FinOps)

The Challenge: Uncontrolled cloud spending with $2.3M annual Azure costs and no visibility into resource utilization, leading to 40%+ waste and budget overruns.

Strategic Outcomes (SRE & FinOps)

  • 42% Cost Reduction: Achieved $960k annual savings through Hybrid Benefit, Reservations, and rightsizing.
  • Real-Time Visibility: Implemented FinOps Toolkit workbooks for granular cost tracking and anomaly detection.
  • Automated Governance: Deployed Azure Advisor recommendations with auto-remediation workflows.

Key Implementations

  • Azure Hybrid Benefit: Enabled AHB for 150+ Windows/Linux VMs saving $380k/year.
  • Reservations & Savings Plans: Committed to 3-year RIs for stable workloads (62% discount).
  • Idle Resource Cleanup: Automated detection and shutdown of unused resources.
  • FinOps Workbooks: Deployed Microsoft FinOps Toolkit for cost anomaly detection.
  • Advisor Integration: Integrated Azure Advisor cost recommendations into CI/CD.

Secure Enterprise GenAI Knowledge Platform (RAG)

Lead Azure Cloud Architect

The Business Context: A regulated enterprise client required a Generative AI solution to democratize access to internal knowledge bases. The initiative was previously blocked by the CISO due to "Shadow AI" risks: public data leakage, lack of determinism (hallucinations), and inability to audit interactions. The goal was to operationalize a "Chat with Your Data" solution that adhered to Microsoft's Responsible AI Standard v2.

Architectural Strategy

Designed a Zero-Trust RAG (Retrieval-Augmented Generation) architecture tailored for strict compliance. The solution moves beyond simple "chat" to a managed AI Foundry workflow, prioritizing automated evaluation, private connectivity, and identity-based access over public convenience.

  • Security Compliance: Achieved 100% network isolation, satisfying the CISO's requirement for "Private Networking with Azure OpenAI."
  • Cost Optimization: Reduced backend model calls by ~30% via Smart Chunking and Semantic Caching (APIM).
  • Hallucination Control: Significantly reduced hallucination rates using Semantic Ranking in Azure AI Search.

Key Architectural Decisions

  • Private Networking: Hub-and-Spoke topology with Private Endpoints for Azure OpenAI, AI Search, and Storage. Zero public internet traffic.
  • GenAI Engineering (LLMOps): Azure AI Prompt Flow for orchestration with automated evaluation (Groundedness, Relevance, Coherence).
  • Identity-First Security: Microsoft Entra ID + Managed Identities for all service-to-service authentication. Zero connection strings.
  • Safety Rails: Azure AI Content Safety filters to block jailbreak attempts and harmful content.
