Willing to relocate: No Technologies: Swift 6, SwiftUI, UIKit, AppKit, HealthKit, StoreKit 2, Core ML, WhisperKit, OpenAI Responses API with function calling, MCP. Supabase/Postgres for the backend side. Résumé/CV: https://www.linkedin.com/in/voltec366 | https://github.com/voltec | https://scopeburn.app Email: [email protected]

Senior iOS and macOS engineer, 14 years. Contract or full-time.

At SHRED, a fitness app with 2.7M users, I built the Apple Watch app from scratch, the live video classes and a video editor, shipped key features of the main app and modernized its Objective-C code.

At StreamLayer I took features from design to release in their iOS SDK for sports-streaming apps: chat, predictions, polls, trivia, leaderboards, in-stream video calls, a live feed. Chat and predictions served up to 30,000 viewers at once.

Tempo, an AI health coach, runs on a HealthKit engine and an OpenAI function-calling layer I built.

Aide, a macOS meeting assistant, is mine end to end: it records system audio, transcribes on-device with WhisperKit, calls tools over MCP and searches across past meetings and chats.

I can take a whole product under my wing and run its development and releases. On several production apps I was the only iOS engineer, owning the architecture, App Store releases, feature flags and gradual rollouts.

I want to build AI features for apps: the client side in iOS or macOS and the backend around it. I do both, with Supabase and Postgres on the server. A startup that needs its first iOS engineer fits too. I invoice through my own sole proprietorship in Georgia.

Senior iOS/macOS engineer, 14 years. I can own the whole product: native app plus a lightweight Supabase or Firebase backend, through App Store release.

- DuetDriver: sole iOS engineer; moved an 8-year-old Obj-C app to SwiftUI without a feature freeze, tests ~60 to 870+

- CoachX: built an AI fitness coaching app from the first commit, sole iOS engineer

- Tempo: health-intelligence core of an AI coach (HealthKit scoring, OpenAI function calling)

- Aide: main macOS engineer on an AI meeting assistant (system audio, on-device transcription, MCP, local search)

- Scopeburn: whole product solo, SwiftUI menu bar app, React web, Supabase backend with realtime sync

- Exported a fine-tuned PyTorch model to Core AI

- Earlier: StreamLayer (30K concurrent viewers), Shred (2.7M+ users)

Open to remote full-time or contract work.
