Writing

Writeups on the agents and tools I've built, and the decisions behind them. Some are work at RDE, some are personal.

  • Learning to ask for help, then learning to be asked Editor's pick

    What it took to stop trying to do everything alone, and what I owe the people who wouldn't let me.

  • Handing the AI work to other teams

    Standing up the company's AI function solo: workflow interviews, a license-holder champion network, a shared agent library, and where it's heading.

  • Scoring the ADA agent against WAVE

    Checking the agent's fixes against a real accessibility tool built on the WebAIM Million. Average score went from 6.3 to 7+ out of 10; contrast errors were the last thing holding it back.

  • Building a local AI agent from scratch with Ollama and OpenClaw

    Skill modules, memory architecture, and why I stopped relying on the cloud.

  • Owning a legacy app across four systems

    What it means to be the subject matter expert on software older than you'd like.

  • How I built a harmonic pattern detector in Pine Script

    Ratio math, pattern memory, and staying under TradingView's token limit.

  • An ADA compliance agent that won't touch code without asking

    Why the human-approval step is the feature.

  • Teaching the ADA agent to write its own patch files

    A senior dev's demo suggestion, SVN patch files I'd never made before, and a "no patch needed" bug.

  • Teaching an agent your codebase's unwritten SQL rules

    Convention extraction, schema verification loops, and where the time actually goes.

  • Testing the limits of vibe coding with Claude

    Free tier, paid chatbot, artifacts, connectors, Claude Code: what changed the outcome wasn't the subscription tier.

  • A few years of watching AI go from confidently wrong to actually useful

    College ChatGPT, a failed vibe-coding attempt, model-switching, and the vibe-coding economy I still go back and forth on.

  • How I ended up building the company's first MCP server

    A CEO's idea, a 40-to-50-hour manual process, and an MCP server I pitched before I'd built one.

  • Redesigning our EMR's UI without a frontend team

    Thirty years without a UI update, no dedicated frontend team, and what AI closed the gap on.

  • Letting the ADA agent scan an entire codebase on its own

    The per-file loop was the bottleneck. A multi-agent full-codebase scan is projected to cut the ADA estimate from 50-60 hours a system to about 5, pending a full-system test.

  • Rebuilding the internal site's frontend in three days

    A second senior dev asked for the demo on the real site: reusable CSS classes, color tokenization, a frontend rebuilt in three days.

  • Two MCP servers I built for my own dev workflow

    Questions about the database and the codebase that used to mean opening SSMS or digging through SVN, answered in natural language instead.

  • Turning the UI rebuild into a design system

    The internal site rebuild is still in testing, and it's already led to the next thing: a documented design system for the team to build from.

  • Scaling our MCP servers with AWS AgentCore, Bedrock, and Lambda

    A meeting with three AWS engineers I hadn't planned to lead, and a crash course in AgentCore, Bedrock, and Lambda to scale MCP servers past my laptop.
