The iOS engineer you call when it has to work.
Ten years of high-stakes apps: medical devices, millions of users, regulated industries. I handle the bits that don't fit in a Jira ticket.
- BLE/NFC device connectivity, background reliability, the stuff that fails in specific RF environments
- Architecture rescue: UIKit → SwiftUI, MVC → TCA, that singleton everyone routes around
- Production firefighting: crashes, performance, "it only happens on that one device"
Pricing
Architecture reviews, hiring help, second opinions on that thing that's been bugging you

Common engagements
Ship your MVP
Working app in the App Store. I build it, handle App Review, and help you hire when you're ready to scale.
Fix the architecture
Codebase your team can ship to without fear. That 4,000-line view controller, the singleton everyone routes around.
Build the hard bits
The feature that works, not the prototype that demos well. Medical device connectivity, Wallet passes, background processing.
Agency oversight
Clear picture of what you're paying for. I review their architecture, audit their code, tell you if they're building a product or billing hours.
Join your team
Extra senior who ships. Embed in your Slack, ship features, review PRs, pair with juniors.
Due diligence
Report you can negotiate with. I read the codebase and tell you what's solid, what's duct tape, and what it'll cost to fix.
