Independent development and publication of 10 cross-platform apps

Independent Developer
Independent Developer
  • Designed and shipped 10 cross-platform apps solo for iOS, Android, and Huawei AppGallery, on a shared Dart platform of 8 reusable packages (auth, sync, analytics, feedback, design system) used fleet-wide; owned every layer from local-first SQLite to store release and in-app purchases.
  • Wrote an app-agnostic cross-device sync engine over Supabase/Postgres: watermark-cursor incremental pull, idempotent UUID-keyed upserts, backoff retry, and soft-delete tombstones under per-user row-level security, verified by an end-to-end harness that runs two devices against production and asserts tenant isolation.
  • Built an internal release-and-ops platform (Node, ~6k lines, ~390 unit tests): one command gates on the test and smoke suites and ships to both app stores, driving the App Store Connect REST API directly and offloading Android builds to a queued Mac-to-Windows build daemon.
