Remexis is a cutting-edge, AI-powered platform providing evidence-based natural medicine guidance for healthcare professionals. To support its evolution into an enterprise-grade solution, we architected and implemented a comprehensive B2B billing and organization management subsystem. This infrastructure enables clinics and medical teams to manage seats, track real-time AI usage, and handle complex subscription lifecycles. By integrating a resilient Stripe-based event pipeline and a granular auditing ecosystem, we empowered Remexis to scale from a single-user tool to a multi-tenant platform ready for global healthcare teams.

Remexis needed to transition from a basic user model to a scalable B2B framework capable of handling multi-tenant organization management and precise feature metering.
We engineered a robust billing architecture using Next.js, Stripe, and Prisma, focusing on high availability and synchronization at the organization level. The solution features a custom webhook listener with advanced idempotency mechanisms, a granular usage tracking subsystem, and a comprehensive admin auditing dashboard to ensure transparency and operational excellence.
“Cristoval is an exceptional developer who truly excels under the pressure of a live production launch. He successfully navigated complex system integrations, ensuring every part of the application was rock solid before handover. What sets him apart is his commitment to security and a clean transition; he verified every audit log and setting to ensure I had full ownership as the client. He is methodical, an excellent communicator, and stays focused until every hurdle is cleared. If you need a professional to take your project from development to a live, functional state, Cristoval is the person to hire. I am extremely satisfied and highly recommend his services.”
