PAI Code Assistants like Cursor, Copilot, and Claude bills double quarter over quarter — and no one owns the line item. Olumia pulls spend and usage from every AI-tool vendor into one place, then surfaces license waste, per-seat economics, forecasts, and allocation by team. /ppbr/ppYou'll own the entire backend: the pipelines that feed the platform, the data model that holds it, the engine that scores it, and the APIs that power the product. You partner directly with the founder, who owns the frontend — you hand off clean, well-modeled data and endpoints. /ppWhat you'll own /ppbr/ppb01 /bbVendor data pipelines /b /ppIntegrations that pull spend, seat usage data from Cursor, Copilot, Claude and more — auth, rate limits, scheduled syncs, normalization. /ppbr/ppb02 /bbData architecture /b /ppThe multi-tenant Postgres/Supabase schema behind spend, seats, vendors, groups tenants — with row-level security and data integrity first. /ppbr/ppb03 /bbRightsizing engine /b /ppLogic that detects wasted over-allocated seats, computes blended per-seat rates, and powers reclaim recommendations. /ppbr/ppb04 /bbForecasting alerts /b /ppProjected-excess forecasting and the notification system that flags spend spikes by user, vendor, or group. /ppbr/ppb05 /bbAPIs automation /b /ppThe edge functions, scheduled jobs, and internal APIs that keep data fresh and feed the frontend — clean contracts, CSV import/export, extensibility. /ppbr/ppb06 /bbReliability direction /b /ppDeployment, monitoring, performance, and the security of sensitive billing data — plus the backend architecture roadmap calls.
