Enterprise AI decision architecture

Context

Enterprise AI must support revenue-generating information products and internal operations without treating accuracy, privacy, or human review as an afterthought.

Executive mandate

Create a platform and operating model that can scale reusable AI capability while keeping the reasoning and review path visible to the people accountable for the outcome.

Architecture approach

Designed a federated enterprise AI architecture with human verification at high-stakes gates, structured challenge for ambiguous cases, and governance signals that turn correction into continuous improvement.

Resulting capability

Reusable capabilities designed for product and operational contexts
Human review retained where expertise and accountability matter most
A clearer path from AI output to evidence, exception, and final decision

Selected work

Willis Towers Watson

Mission-critical systems modernization

Context

A global advisory environment needed to modernize operational systems while protecting resilience, service delivery, and regulatory obligations.

Executive mandate

Translate modernization goals into an enterprise architecture that could support change without treating reliability and compliance as a later phase.

Architecture approach

Developed cloud transformation and security architecture patterns that connected high-volume operations, cross-border requirements, and fault-tolerant platform design.

Resulting capability

A scalable architecture path for critical client infrastructure
Security and compliance considerations embedded in the modernization design
A clearer foundation for reliable service evolution

IBM

Enterprise architecture for hybrid environments

Context

Large legacy estates can slow product delivery when integration and modernization are treated as separate problems.

Executive mandate

Create target-state architecture that connects legacy capabilities with modern platform patterns without losing the operational knowledge already embedded in the estate.

Architecture approach

Led hybrid-cloud and integration roadmaps across complex enterprise environments, aligning service refactoring, platform design, and operating priorities.

Resulting capability

Architecture frameworks for complex enterprise change
A practical route from legacy constraints to modern platform capability
Technology decisions tied to operational continuity rather than novelty
