About the Client
TriFundit is a web app that links everyday endurance activities to charitable giving via per‑mile sponsorships charged monthly, turning workouts into donations for causes and registered nonprofits. The product vision required consumer‑grade UX, reliable fitness app integrations, transparent pledging, and compliant payment flows that scale during weekend spikes and event seasons.
Challenges
- Fragmented fitness APIs caused sync delays and mismatches
- Monthly pledge metering needed reliable audited billing
- Sponsor conversion dropped during invite and checkout
- Weekend traffic spikes degraded mobile Web Vitals
- Tenant isolation and data compliance required rigor

Architecture Overview
The platform runs multi‑tenant Postgres schemas with tenant‑scoped provider and payment keys for clean isolation. Next.js App Router with RSC delivers lean SSR dashboards, while ISR and image optimization keep public pages fast during peaks. A queue‑driven metering and billing layer signs requests, retries with backoff, and applies circuit breakers across provider and payment APIs. Workers handle heavy tasks so interfaces remain responsive, with centralized tracing and metrics to protect SLAs.
