I designed and delivered the Cassie Developer Hub as a centralised, self-service documentation platform to support external developers and internal teams. Working closely with product, engineering, and marketing stakeholders, I helped define the structure, content strategy, and user experience to ensure the hub aligned with both technical requirements and product positioning. The result was a scalable developer portal that reduced onboarding friction while presenting the API clearly, consistently, and professionally.

I authored and maintained a full suite of REST API documentation, including conceptual guides, detailed reference material, and interactive examples to support real-world implementation. This included integrating Postman collections, analysing JSON responses, and implementing JavaScript-driven interactivity to allow developers to explore endpoints and workflows more effectively. Alongside the public-facing content, I produced architecture overviews, component documentation, and technical design artefacts to support engineering collaboration and internal onboarding.

To ensure long-term sustainability, I established reusable documentation templates, standards, and workflows that could scale with future product development. I supported handover and training for internal teams, enabling ongoing content maintenance and iteration without reliance on external support. This approach ensured the Developer Hub remained accurate, extensible, and aligned with evolving product and engineering practices, while continuing to deliver value to both developers and the wider organisation.
