5 Secrets We Learned While Building a Bank in 16 Months
summary
Claims a full banking stack gets built and launched in 16 months after an 8-week Ruby rewrite of a 500k-line C# app, using Rails, PostgreSQL, Redis and Elasticsearch, with 70% test coverage on the prototype. It actually issues loans (average ticket $15,000), underwrites with an in-house credit policy and targets 15% simple interest refinancing, cuts vendor turnaround from weeks to days, and scales hiring to support production.
