AI automation · Nashville, TN

I build the automations that keep Nashville operations moving.

n8n workflows, voice agents and Microsoft Copilot, wired into the tools a team already uses. I design them to be trusted: clear hand-offs, humans in the loop, and a plan for when the AI is wrong.

My Resume Let's Chat

How it fits together

How a voice agent intake flowsThe call becomes a record someone can act on.
  1. Call comes in Twilio
  2. Agent talks Vapi
  3. Webhook fires Call data
  4. Record filed Organized
A pattern I reuse in n8nTriggers vary. The approval step is there when a human should decide.
  1. Something happens Gmail, Stripe, a schedule
  2. Workflow sorts it n8n
  3. Human checks Telegram, when it matters
  4. Work lands Trello, Airtable, Gmail

What I've actually done.

Client work and things I run myself. Each one links to the real project.

  1. Healthcare Realty Trust · Tenant sites

    Days-long turnaround became minutes.

    Site edits used to go through an outside contractor and take days. I built an in-house system the team runs themselves, so updates now take minutes.

    ~$240k saved per year in maintenance
  2. Healthcare Realty Trust · Power Automate + BrightSign

    Directory updates in seconds, not minutes.

    A Power Automate workflow reads each Jitbit ticket, finds the building and pushes the update to the right BrightSign playlist. About 250 requests a month used to take a technician 5–10 minutes each.

    Read the case study
    ~15 sec per update, down from 5–10 minutes
  3. n8n · Agentic workflows

    The small machines that keep my week moving.

    Gmail to Trello, Stripe to Trello, a LinkedIn content pipeline with a Telegram approval step so I stay in the loop, a lead-scout agent and uptime monitoring.

  4. Zinnia · Indie build

    An admin assistant I message on Telegram.

    Zinnia reads Gmail, updates Airtable and keeps context in Redis, running on local models. I use it daily, which is the fastest way to find out what breaks.
