Architecture portfolio

Anonymized diagrams for enterprise-scale thinking.

Reference architectures that show how I reason about integration, AI-assisted delivery, ServiceNow workflows, secure cloud foundations, agentic systems, and governance. They are intentionally vendor-neutral and anonymized.

These diagrams demonstrate architecture patterns, not proprietary client systems. Names, data flows, vendors, and operational details are generalized for public sharing.

Enterprise integration

API-led integration across enterprise systems

A pattern for connecting business applications through governed APIs, event streams, transformation services, and observability layers without hard-coding every system-to-system dependency.

  • Canonical integration contracts and versioned APIs.
  • Async events for operational resilience and decoupling.
  • Centralized logging, tracing, policy checks, and alerts.

GenAI/RAG architecture

Retrieval-grounded enterprise assistant

A governed RAG flow for knowledge-heavy enterprise use cases, balancing retrieval quality, prompt safety, access control, citation traceability, and human escalation.

  • Document ingestion with chunking, metadata, and embeddings.
  • Policy-aware retrieval before model generation.
  • Grounded responses with citations, review, and feedback loops.

ServiceNow workflows

Enterprise service workflow modernization

A ServiceNow-oriented workflow pattern for turning request intake into governed routing, approval, fulfillment, integration, and continuous improvement.

  • Role-aware request intake and SLA-aware routing.
  • Approval and fulfillment paths with integration hooks.
  • Knowledge capture and reporting for operational maturity.

Secure cloud architecture

Cloud landing zone with defense-in-depth

A secure cloud foundation pattern that separates identity, networking, application runtime, data services, secrets, monitoring, and compliance controls.

  • Network segmentation, private subnets, and controlled ingress.
  • Identity-first access, secrets management, and encryption.
  • Runtime monitoring, vulnerability signals, and audit evidence.

Agentic AI systems

Multi-agent delivery orchestration

A controlled agentic AI pattern where specialized agents plan, retrieve, generate, validate, and report, while shared governance prevents untraceable automation.

  • Planner, researcher, builder, validator, and reviewer roles.
  • Shared memory, tool policies, and approval boundaries.
  • Evaluation gates before committing generated outputs.

Observability and governance

Operating model for reliable AI-enabled systems

A governance pattern that connects telemetry, audit trails, quality evaluation, risk signals, incident response, and executive reporting for production-grade systems.

  • Metrics, logs, traces, prompts, and model-output auditing.
  • Policy checks for data access, security, and quality drift.
  • Incident response and improvement loops tied to evidence.
