Self-initiated cross-platform (iOS + Android) astrology & tarot product — “you were born with a frequency”. Blends Western astrology, tarot, the Mayan Tzolkin and Human Design into a single personal-insight app with LLM-authored interpretations, connected and manual profiles, synastry between people, and a freemium paywall.
Kotlin Multiplatform + Compose Multiplatform, one shared codebase across Android, iOS and JVM. Built a pure-Kotlin ephemeris engine replacing SwissEph — VSOP87 planets, ELP2000 Moon, PLUTO95 and analytic nodes accurate to a few arc-seconds — powering natal charts, transits, synastry, event finders and astrocartography with zero native dependencies in common code. Persistence via SQLDelight; DI with Koin. Backend is a Directus + Ktor stack (auth, day/pair caches, LLM interpretation jobs, name→gender, invitations, tracing) live at api.getsintonia.com, deployed through a Jenkins pipeline with git-crypt-encrypted secrets. Android beta ships via Firebase App Distribution; marketing site on Astro.
