AI-Powered Developer Documentation for International Bank
Organically grown documentation, rising support tickets
The mobility payment division of a major international bank provides payment solutions for the automotive industry. Their technical documentation for developer clients had grown organically over the years: inconsistent terminology, poor searchability, missing code examples.
Competitors had significantly better developer portals. Support requests and escalations were mounting. Documentation was out of sync with product releases.
