Tools we've shipped

A selection of what we've designed, built, and put into production. Several have live demos you can try right now, no sign-up required.

Work & automation
Takeoffs

Drawing Takeoff Studio

Mark up a plan and it builds a finished square-footage schedule for you, so takeoffs happen without counting by hand.

Estimating

Budget Analyzer

Move a few live sliders and watch a full budget build itself across every CSI division. Fast, early numbers you can actually trust.

Bid analysis

Bid Analyzer

Checks any subcontractor's bid against the real scope and flags where it's padded. Roofing is the worked example: it caught a bid for 86 drains when the job needed 3.

Automation

Email Automation

Reads incoming email and drafts replies in your voice, so the inbox mostly handles itself and nothing important slips through.

Open source

Bank Reconciliation Tool

A free tool that matches a bank statement to your books in seconds. Hit reconcile and cleared lines turn green, exceptions flag amber, and the balances tie out. Works with QuickBooks, Xero, and more.

AI vision

UnitPhotoSorter

A bot that reads site photos from a group chat and files each one into the right folder on its own, 24/7. Tested at 100% accuracy on a real batch.

Trackers
Document automation

Submittal Tracker

Drop in a submittal and it reads itself, then logs straight into a clean tracker with full revision history. No manual entry.

Compliance

DOT Permit Tracker

Keeps every DOT permit in one place and flags what's expiring in red and amber, so nothing lapses by surprise.

Finance

Invoice Tracker

Drop in an invoice and it reads itself, then logs neatly into a spreadsheet with costs and approvals tracked. No more manual data entry.

Rollout & strategy
AI adoption

Company-wide Claude Rollout

Led the rollout of Claude across an entire organization, getting every team set up, trained, and actually using it, so AI became part of how the company works day to day.

Side projects
Web app

NYC Ticket Heat

A live, block-by-block map of where NYC parking tickets actually land — all five boroughs, 7.6M real citations, by day, time, and violation type. Drop a pin and it reads the posted meter rules, gives your real odds if you skip the meter, and tells you whether it's cheaper to risk it or pay.

There is more where these came from. See everything on GitHub.
