McKay Smalley

Senior Software Engineer · Agentic AI Systems

I build production AI infrastructure and scalable backend platforms — from MCP integrations and automated code review to systems that move millions of messages.

What I’ve been building

Ten years shipping production software — recently focused on agentic development, high-assurance systems, and platforms that stay reliable under real load.

  1. Senior Software Engineer

    2025 – Present

    One Claim Solution · Remote

    • Pioneered Cursor-based agentic development: custom MCP integrations, shared context patterns, and a production MCP gateway across Postgres, logs, errors, and Redis.
    • Designed and owned an end-to-end AI code review tool from prototype through company-wide adoption.
    • Scaled communication backends for 900k+ conversations and 7.3M+ messages; cut timeout bottlenecks by moving heavy LLM work off the request path.
