01 — SELECTED WORK

Three sites,

  2. Tempo Analytics

    Real-time product analytics for indie SaaS — from event stream to insight in under a second, without the enterprise bloat.

    A collaborative digital archive for a Nordic photo collective — search-first, offline-ready, and fast on a decade-old laptop.
