I keep the shop running,
and write the software that helps.

Procurement used to live in email threads and a shared spreadsheet. This tool stores every RFQ, the vendors it went to and each response, then ranks quotes by price, lead time and past on-time delivery. Buyers see what's overdue at a glance, and the history makes the next quote faster.

• Side-by-side quote comparison with landed-cost math
• Automatic reminders for vendors that haven't responded
• Vendor scorecards built from real delivery history

• Flask
• SQLite
• HTMX

Small collectors on each machine report cycle state to a central service. The board shows utilization by shift, flags machines that have sat idle too long, and keeps a history so downtime conversations start from data instead of memory.

• Per-machine run / idle / alarm state with timestamps
• Shift utilization summaries emailed each morning
• Runs on low-cost hardware mounted at the machines

• Raspberry Pi
• Python
• MQTT
• Node.js
• Chart.js

Inserts, end mills and bar stock are tracked with cheap barcode scanners. When a quantity falls below its reorder point, a draft purchase request is created with the preferred vendor and last price filled in, so nothing runs out mid-job.

• Scan-to-issue workflow that takes seconds at the crib
• Min/max reorder points per item and per job
• Usage reports that feed tooling budget decisions

• Python
• PostgreSQL
• Barcode scanners
• Power Automate

Pulls open work orders from the ERP export, estimates run time from routing data, and lays jobs out on a per-machine timeline. Jobs at risk of missing their ship date turn amber well before they turn into a problem.

• Imports nightly ERP exports automatically
• Capacity view per machine and per shift
• Late-risk warnings based on remaining operations

• JavaScript
• Node.js
• SQL
• CSV / ERP export

A set of scripts for catching mistakes early: list every tool a program calls, estimate cycle time from feeds and moves, and show a readable diff between two revisions of the same program.

• Tool list and offset summary for setup sheets
• Rough cycle-time estimates from feed moves
• Revision diff that ignores comments and whitespace

• Python
• CLI
• pytest

No framework and no build step. Colors and motion live in separate stylesheets so they're easy to tune, the dither reveal is a small canvas script, and everything degrades gracefully with JavaScript off or reduced motion on.
