Independent Mobile App Business
Skills exercised
Built a mobile app business starting in 2014 and formalized it as a single-owner LLC in 2021. Started with around 20 apps, unpublished the 19 unprofitable ones, and focused on the profitable product. That app has since exceeded 50,000 lifetime sales across iOS and Android.
Product development and maintenance
Shipped the initial apps on Android, then rebuilt the retained product in 2018 and released its first iOS version. Later migrated to Flutter and Dart to maintain both platforms from a single codebase.
The product continues to generate sales with minimal ongoing maintenance. Updates address platform compatibility and content changes. Average annual workload is a few days during the winter off-season.
Companion content tooling
Python tooling for content collection, deduplication, and ingestion keeps routine updates maintainable.
Business operations
Everything handled directly as sole owner: LLC formation, accounting, Apple Developer Program, Google Play Console, App Store Connect submission and reviews, tax filings, payment processing, customer support workflow, revenue tracking.
