OWASP-aware code security audit — finds auth, input, secret, and dependency issues with remediation.

Build production-grade Claude API apps with prompt caching, tool use, streaming, and model migration baked in.

Wire Hilt dependency injection the right way — modules, scopes, ViewModels, WorkManager, testing.

Background jobs done right — constraints, retries, chains, periodic work, expedited jobs, foreground service.

Wire Firebase right — Auth, Firestore, Realtime DB, Crashlytics, Analytics, Cloud Messaging — via the BoM.

SwiftData (iOS 17+) the production way — @Model, @Query, CloudKit sync, predicates, migrations.
