Strategic Enterprise Architecture
🎯 Business Modeling • ⚙️ Process Management • 🛡️ IT Governance • ☁️ Secure Hybrid Infrastructure

Enterprise Architect focused on aligning business strategy, operational processes, and IT governance with secure, scalable hybrid infrastructures.

This GitHub profile is a strategic portfolio showcasing architectural frameworks, governance models, and transformation blueprints developed across enterprise environments.

It is not code-centric. It is architecture-centric.

Each architectural case study follows a structured model:

1. Business Context
2. Current-State Assessment
3. Target Architecture Blueprint
4. Governance & Control Model
5. Process Flow Design
6. Risk & Trade-off Analysis
7. Reusable Architecture Patterns

• Architecture is strategic, not technical documentation
• Governance must be embedded, not layered
• Process discipline enables scalable transformation
• Security is structural, not reactive
• Complexity must be intentionally designed

• Enterprise Architecture Strategy
• IT Governance Frameworks
• Business Process Integration
• Secure Hybrid & Cloud Architecture
• Transformation Advisory

• 00-Architecture Principles
  Enterprise Architecture principles for designing secure, resilient, AI-ready hybrid infrastructures across network, cloud, and security domains.

• 01-Hybrid-Multi-Cloud-Blueprints
  Patterns for regulated industries (healthcare & finance), secure workload distribution, data sovereignty, resilience, and zero-trust segmentation across on-premises and multiple clouds

• 02-Network-Modernization
  Large-scale MPLS-to-SD-WAN transformations, data center optimization & relocation methodologies, risk-mitigated cutover strategies

• 03-Zero-Trust-Security
  Practical application of zero-trust principles using Cisco ISE/NAC, identity driven micro-segmentation, endpoint protection & SecOps practices

• 04-Cloud-Native-Governance
  Cloud agnostic governance models, AKS / Kubernetes hardening, policy enforcement patterns, compliance alignment (CIS, regulatory frameworks)

Open to interesting challenges in enterprise architecture, hybrid cloud strategy, zero trust transformation, and AI infrastructure foundations.

Feel free to explore the repositories — feedback and thoughtful questions are always welcome.
