native iOS and macOS apps built with the same delivery discipline I bring to advisory work.
Why this portfolio exists
When clients hire me to build their Slack automation or Jira pipeline, they're asking: can this person actually ship? These apps are the answer.
They run on a single Swift package called AppFoundation — shared analytics, monetisation, and onboarding. Free versions use subscriptions; paid one-time-purchase alternatives are built from the same codebase using compile-time flags. The same approach — shared architecture, reusable components, AI-assisted speed — is how I build client automation systems under fixed-price, 2-week delivery.
Apps across multiple countries, each localised for the specific exam. Official questions, mock tests, adaptive progress tracking. Built on the same SwiftUI + AppFoundation stack — each shipped in under 2 weeks.
