spotaa.eu

Spotaa is a composable OOH (out‑of‑home) advertising platform designed for speed and clarity. The core experience focuses on fast inventory search, transparent pricing, and predictable booking flows.

I built a typed backend (tRPC + Prisma + PostgreSQL) with clean domain boundaries and a minimal front‑end surface that keeps the UI crisp under load. Media uploads are processed and versioned; availability is computed on the fly with caching where it compounds.

Operationally, the system favors small, auditable actions and clear states. The result is a premium, low‑noise product that scales with teams and campaigns without getting in the way.
