LK Tracker
The carrier's whole back office in one app, on a phone in the cab or a desk at home.
- Purpose
- Two spreadsheets were running a trucking company, and losing. I replaced them with one app for loads, trips, expenses, broker payments, fuel taxes, compliance dates and a monthly P&L.
- Stack
- TypeScript, Fastify, SQLite, React as an installable phone app, Tailwind, an AI API that reads rate confirmations, connections to banking apps, cloud computing.
- Results
-
- 399 commits since May 2026; it runs the carrier in production.
- 143 API routes, 43 tables, 118 test files.
- Drop in a stack of rate confirmations and AI reads every one. Nothing saves until you approve the preview.
- A full accounting audit against production on July 29, 2026 found every payment split exact.
