I build full-stack products and the servers they run on. Three apps live, all self-hosted.

$ git log --all --graph

Twelve years,
one repo.

Every branch from init to HEAD. Hover or tap a commit to read it.

$ git shortlog --author=aaron

Three roles.
One layer deeper each time.

From dashboards down to bare metal, across two companies.

  1. data

    Lernmore Consulting

    Lead Analyst

    Forked the work branch. Built the analytics side: interactive Streamlit dashboards backed by FastAPI services, and Python pipelines that turn raw data into reporting.

  2. metal

    PLCcode.ai

    DevOps Engineer

    Built the company's on-premise infrastructure from bare metal up: virtualization, routing, internal PKI, identity, and the MQTT broker their PLCs publish to.

Three apps.
In production.

Built solo, deployed on my own servers. Open one.

Every request
rides a line.

The self-hosted stack under those apps, drawn as a transit map. Pick a station or a line. Dotted track is what I build next.

Down to
bare metal.

The on-prem stack I build and run: Proxmox from the rack up, VMs to certificates.
