A group challenge and gamification engine for B2B and B2C users.
A wearable "App Store" backend to manage 3rd-party app submissions, approvals, and delivery.
A robust 3rd-party API to support partner integrations.
System Maintenance: Monitor system performance, diagnose bottlenecks, and ensure the reliability, security, and scalability of the entire backend platform.
Internal Tools: Collaborate with front-end developers to support and enhance our internal admin portal for analytics, device management, and customer support.
Collaboration: Work effectively within our Agile team, communicating progress clearly and collaborating with mobile developers, designers, and project managers.

What You Bring:
