Arsum connected Attuned Health's Shopify customer journey with a custom results application, structured AI-assisted report preparation and practitioner review. The delivery included React interfaces, Shopify App Bridge, a Node.js/Express backend, SQL storage, OpenAI and Anthropic integrations, and AWS infrastructure. The application prepares report sections in stages, assembles the results and lets a practitioner review or regenerate them before release. Arsum also implemented automated tests, deployment procedures, monitoring and ongoing maintenance. The project is live and continues to evolve. Published screenshots use demonstration data.

Sidera is an Arsum-owned product connecting an astrology calculation engine, planning calendar, contextual AI chat and compatibility features across web and Android. Arsum built the Python backend, React web application and Flutter Android application, along with onboarding, subscriptions, analytics and operational monitoring. The architecture separates domain calculations from AI interpretation: the backend prepares context and the model explains it. Users retain the choice of how to act.
