Let's Work Together See the Work

I bring an entrepreneurial mindset to technical problems, and AI engineering lets me take on almost anything. Here are some of the projects I've been working on:

Founder

Golf In Club

A booking, membership, and payments platform I built for indoor golf clubs. Clubs sell bay time, run memberships, and open their doors 24/7 without staff on site.

What Clubs Get

  • Open 24/7 Without Staff

    Members unlock the door with their booking, through Brivo, Igloo, or Shelly smart locks.

  • Get Paid at Booking

    Stripe, Apple Pay, and Google Pay, with peak pricing, member rates, and guest fees built in.

  • Memberships Your Way

    Initiation fees, roles, and booking limits for every tier.

  • Sessions That End on Time

    A bay timer warns players and locks the screen when their time is up.

  • Know What's Working

    Reports on usage, revenue, and peak times.

  • Fits Any Club

    A hosted site, or a WordPress plugin on the club's own site.

Hardware

Pace Wireless

Pace Wireless is an embedded wireless engineering firm in the Chicago area and a Morse Micro HaLow design partner. I designed and built its new HaLow sensor platform end to end: a custom board, its firmware, the cloud behind it, and a live dashboard for every device.

The live dashboard for every sensor

  1. Design

    Circuit boards in KiCad, sealed enclosures in FreeCAD.

  2. Build

    Firmware for the radio, the cloud behind it, and the dashboard.

  3. Test

    I built the test bench on an open source stack, and every design is reviewed and validated by engineers with 30+ years of experience.

Workflow

How I Build

I've made a career of connecting the dots across business and engineering teams. I've always been hands on, writing code long before AI, but the biggest projects are team efforts, and at work they still are. What's new is how far I can take an idea on my own, from spec to a working product.

  • Prompts and Specs

    Sized to the job, from a quick prompt to a full spec. I know when to spell things out and when to let the model decide.

  • Model Fit

    Frontier models for hard reasoning and long runs. Lighter, faster models for quick edits and research.

  • Loops and Long Runs

    Agents loop toward a goal, checking and improving each pass. Long runs get checkpoints where I validate the work.

  • Subagents

    Big jobs split across agents that research, build, and review, each with only the context it needs.

  • Context

    Tuned skills and context for every project, so agents start with the right conventions.

  • Tools

    Claude Code, Codex CLI, Cursor CLI, and OpenCode, all run through T3 Code across my servers, machines, and devices.
