Designed and built end to end: native iOS (Swift) and Android (Kotlin) apps, two web apps, and a localized marketing site, backed by Go serverless services on AWS (Lambda, DynamoDB, Cognito, CloudFront). Includes a custom 364-day calendar engine with astronomical anchoring, store-native subscriptions with regional pricing across worldwide App Store and Google Play markets, passwordless and social sign-in, localization into 13 languages, home-screen widgets, and CI/CD pipelines to both app stores and the cloud.
