Founder & Owner · After Hours Data Systems

Single-owner mobile app business I started in 2014 and formalized as After Hours Data Systems in 2021. Started with around 20 apps, unpublished the 19 unprofitable ones, and concentrated development on the profitable product. That app has since exceeded 50,000 lifetime sales across iOS and Android. Today, it operates with minimal ongoing maintenance.

Product development and maintenance

Taught myself mobile development and shipped the initial Android apps. After narrowing the portfolio to one product, rebuilt it in 2018 and released the first iOS version, expanding sales to both platforms.

Later rebuilt the app in Flutter and Dart to maintain iOS and Android from a single codebase. Marketing is largely organic through App Store and Play Store search. Updates address platform compatibility and content changes, with an average annual workload of a few days during the winter off-season.

Product and business ownership

I handled development, releases, customer support, accounting, and store administration directly. Narrowing the portfolio let me focus on maintaining one product as mobile platforms and content requirements changed. I rebuilt it twice, most recently in Flutter and Dart.

Companion tooling

Python tooling for content collection, deduplication, and ingestion. Keeps the content pipeline maintainable as updates are needed.

Ongoing maintenance

The mobile product runs alongside other work, with sales through the App Store and Google Play. Maintenance addresses platform compatibility and content changes and typically takes a few days a year.
