MCP Servers & Agents

Plan, deploy, and operate Model Context Protocol servers/agents so your teams can orchestrate tooling safely. Includes capability mapping, auth, and observability.

ArchitectureSecurityIntegrationRunbooks

How I engage

  • Architecture & AI assessments (2–4 week sprints)
  • Fractional architect (1–3 days/week; design-first, hands-on when needed)
  • Architecture reviews & second opinions
  • AI/agent pilots & PoCs (MCP, tool orchestration, Python/LLM scaffolding)

Step 1

Discovery

Clarify domains, constraints, SLAs, risks, and the smallest valuable slice.

Step 2

Architecture

Target state and migration plan with decision records, reference contracts, and safety/operability guardrails.

Step 3

Delivery

Guided build and PoCs (Python/agents, code gen, CI/CD, observability) with handover playbooks—hands-on where it accelerates the team.
