Where I can help

Engage me for architecture, a complete solution design, or AI implementation. Each starts with your business problem and an agreed scope.

Enterprise view

Enterprise architecture

  • Current-state view
  • Target architecture
  • Transition states
  • Staged roadmap
  • Decision log

When you need a clear view of the estate and a defensible direction for change. I establish ownership, dependencies and priorities with your business and technology leads.

First step · Architecture decision review

End-to-end design

Solution design

  • High-level design
  • Sequence flows
  • API and integration specs
  • Security and NFRs
  • Migration and coexistence plan

When complex requirements need one coherent end-to-end solution. I resolve interfaces, security, migration and design decisions with your teams and vendors.

First step · Solution design review

Governed automation

Spec-driven agentic AI automation

  • Written specification
  • Governed workflows
  • Separate verification
  • Traceability record
  • Prototype, MVP, full solution

When repeatable work is ready for automation with clear boundaries and human oversight. Agentic AI means agents that carry out multi-step work, not just answer questions. I build them with secure access, evaluation and traceable outcomes.

Agentic architecture in practice

Ask for a walkthrough

  1. Requirements
  2. Specification
  3. Build
  4. Independent verification
  5. Human approval
  6. Evidence and release

Spec-driven means every step traces back to an agreed, written specification, so the work stays reviewable end to end. For example, tests are written by separate agents that never see the code they check.

Enterprise architecture automation

Requirements, Architecture & Design Automation

I design agentic workflows that turn business requirements and enterprise knowledge into architecture options, impact analysis and solution designs. Specifications, diagrams and review feedback stay connected, with architects retaining design authority.

Enterprise grounding · Architect-led decisions

Operational community platform

Software Lifecycle Automation

I designed and built end-to-end SDLC automation for a free community platform that is now operational and self-managed. Agentic workflows take change requests through requirements, wireframes and approval, then architecture, implementation, testing and release. Human approvals and independent verification are built into the workflow.

Architecture ownership

I connect requirements and design decisions, with explicit trade-offs.

Knowledge you retain

Maintainable specifications and operating guidance, developed with your architects and engineers.

Prototype, MVP or complete solution.

Bring me the challenge. I can shape the enterprise architecture, design the end-to-end solution and build spec-driven AI automation around it, starting at the stage you need.

  1. Prototype

    Test the approach against a focused use case, then agree whether it earns an MVP.

  2. MVP

    Build the essential workflows, integrations and controls, proven in use before scaling.

  3. Complete solution

    Extend the architecture, validate readiness and hand over for operation at scale.
