LeaseLens
An equipment lease management product I built from the ground up. Upload a lease PDF and the terms, obligations, and deadlines come back extracted, so a business never auto-renews into bad terms by accident. It is my own product, and the proof that I can ship a full production SaaS on my own: design, application, AI pipeline, billing, and infrastructure.

The brief
Every business with a copier, a forklift, or a fleet of laptops has lease obligations, and most of them live in a spreadsheet owned by whoever got stuck with the job. Renewal dates slip past. Leases auto-renew into terms nobody would have agreed to. Asking “what do we owe over the next twelve months?” costs somebody an afternoon.
My co-founder at Harbor Bridge Ventures had the idea and I built the product. The bet was that AI can now read a contract the moment it is signed and keep track of what it obligates you to, so nobody has to retype terms into a spreadsheet and babysit the dates by hand.
What I built
- AI extraction pipeline
Upload a lease PDF and the terms, payments, obligations, and critical dates are pulled out automatically. Every extracted value links back to the exact place in the document it came from, so you can check any number against the lease before acting on it.
- Deadline tracking and digests
A notification engine on Celery and Redis watches every renewal and termination window and sends a daily digest. The dashboard opens with “3 leases need attention” rather than a table of 47.
- Subscription billing
Stripe subscriptions with multi-tenant organizations, per-plan quotas, and webhook-driven billing state. Self-serve from signup through upgrade with nobody in the loop.
- Production infrastructure
A Django REST backend and a React and TypeScript client, deployed to AWS with Terraform and Docker. Session auth, CSRF protection, monitoring, and CI, all in place from the first deploy.
The outcome
LeaseLens is live at app.leaselens.io, operating under Harbor Bridge Ventures LLC, with billing self-serve from signup through paid subscription. The product leads with the handful of things that need a decision this week rather than reproducing the spreadsheet it replaced.
Is there a workflow AI could take off your plate?
If your business runs on documents, deadlines, or data entry that somebody dreads, that is a tool I can build for you. It gets scoped to your problem and priced before work starts.
