Project Solution

Railwaymen collaborated on scope, specifications, design, prototyping, and full-stack development for an IoT smart charging cable product. They ran a strategy phase with design and user testing, built prototypes in InVision, implemented native iOS and Android apps, developed backend services and APIs, created an SDK for third-party apps, and delivered an administration dashboard. They built and maintain the codebase, handled integrations with third-party services (e.g., Twilio, SendGrid), and operate in sprints using standard project-management tooling.

Project Outcome

  • Launched a fully functioning product on the App Store in April 2017.
