Lab

The idea I want to build next, and the things I have built so far.

01Configure, don't commission.

The loan platform I worked on took about 18 months to go live. That is not unusual for bank software. Banks buy lending systems as turnkey projects, and every later change goes back into a vendor's queue.

I think lending software should work like Jira. Each bank sets its own process, rules and flow, and changes them itself.

Tessera is the concept I am building around that idea: loan origination and credit decisions as a configurable platform, offered as a service rather than a project. Below is one small working piece of it.
