- 🛒 Today I build ads and promoted products for a Fortune 500 retailer's iOS app.
- 🧱 I care about code a team can still change years later: clear boundaries, real tests, and reviews that follow the team's own decisions.
- 🧪 Clean Architecture, TDD, and modularization are my default; Swift Testing over XCTest.
- 🤖 Learning how AI agents fit into real Swift codebases, and Swift Concurrency in depth.
- 🎓 Moderator at Essential Developer since 2022.
- ✍️ I write about the parts of iOS that don't fit in a tutorial at swiftyjourney.com.
