AI-Powered Developer Documentation for International Bank
Challenge

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.

Our Contribution

What we delivered

  • AI-Powered Documentation

    Leveraging AI for creating and migrating technical documentation —hundreds of API pages, tutorials and examples rebuilt efficiently.

  • Process Redesign

    Integrating product management, development, documentation and support. Documentation as part of the DevOps cycle, not an afterthought.

  • Strategic Advisory

    Three-stage roadmap (Light, Foundation, Strategic) developed with a clear recommendation on the right level of investment.

  • Technology Selection and Implementation

    Evaluating modern tools (Docusaurus, Markdown, Git-based workflows). Proof-of-concept, MVP, then incremental expansion.

  • Change Management

    Collaborative workshops with internal teams and editor training for sustainable adoption.
