An international remittance provider needed partners to be able to onboard themselves, choose their own corridor, and integrate without a six-week implementation call. We built the platform that let them.
Remittance businesses grow by adding partners and corridors. Both were bottlenecked on the same thing: every new partner meant bespoke integration work by a team that was already the constraint. The commercial ambition — hundreds of partners, dozens of corridors — was arithmetically impossible with the delivery model in place.
Three things had to become self-service without any of them becoming unsafe: partner onboarding, corridor selection, and developer integration.
The platform was built on Java Spring Boot with a ReactJS front end and Postgres underneath — a deliberately conventional stack for a system where the interesting risk is in the money movement, not in the framework choice.
The point of the engagement was never the portal. It was removing a per-partner cost that scaled linearly with the business. Once integration became something a partner’s own developers could complete on their own schedule, adding the hundredth partner cost roughly what adding the tenth had.
Stack — Java Spring Boot · ReactJS · Postgres · NodeJS

It usually shows up as an implementation team that can never quite keep up. Tell us where yours sits and we will scope what it takes to remove it.
