Apple Platforms Engineer · 14+ years

I build the iOS & macOS apps
that brands trust
with their audio.

14 years. 30+ apps shipped. I take Apple-platform products from zero users to enterprise scale — specializing in real-time recording, AVFoundation audio pipelines, streaming, and SDK architecture. Startup speed, brand-name quality.

Selected work

Backtrack — iOS

Lead iOS Engineer · Yac, Inc.
~$2M ARR

Built the iOS app from scratch — zero to a live-event B2B product deployed at Disney, HPE, Tiffany&Co, Great Wolf Lodge, Topgolf, and LG. Led mobile engineering (iOS + Android, 3-person team) close to CEO and CTO, translating raw product vision into technical specs and shipping under real conference pressure.

  • Deep AVAudioEngine work: Not just a recorder — analyzed raw bytes being written in real time and handled every AudioSession event: interruptions, route reconfigurations, and advanced audio context edge cases that most engineers never encounter
  • Offline autopilot: WebSocket-driven meeting sync with graceful degradation — if the socket dropped, the app continued recording and syncing independently with zero user intervention
  • Full media pipeline from scratch: audio export, multi-segment merge, image generation, and video assembly (audio + thumbnail) — every piece owner-built
  • OCR badge scanning: Custom camera view with Vision framework for real-time badge reading at live events — attendee check-in at scale
  • PhoneContext system: Original idea and implementation — real-time device orientation/position detection (pocket, facing up, facing down, in hand, on table) to dynamically control camera and recording behavior
  • CI/CD + releases: Owned the full release pipeline, App Store submissions, and daily production monitoring via Sentry and Mixpanel
  • Spec authorship: Received raw CEO/CTO briefs, translated them into full technical specs, and led implementation across the team

Backtrack — Mac

Lead macOS Engineer · Yac, Inc.
#1 in 10 countries Setapp Featured

Shipped Backtrack to #1 in the Mac App Store across 10 countries, then pivoted that B2C momentum into a full B2B enterprise play — owned hardware, MDM deployment, and on-site event infrastructure for live events at Disney, Topgolf, and HPE.

  • Menubar app architecture: Built with AppKit + SwiftUI — simultaneously records screen, system audio, and microphone, then merges all streams into a single polished output
  • Screen + audio capture: Leveraged ScreenCaptureKit and AVAudioSession for low-latency, background-safe capture that survived sleep, lock, and OS interruptions
  • Calendar integration: Meeting detection from Calendar events to auto-trigger and stop recordings at exactly the right moment — no manual action required
  • GraphQL + Apollo: Backend sync using Apollo Swift for real-time state across devices during live events
  • Swift Concurrency throughout: Structured concurrency for safe parallel capture, stream merging, and upload — no race conditions, no data loss
  • Enterprise infrastructure: Vision OCR badge-scanning pipelines for physical attendee check-ins; MDM deployment for large-scale hardware rollouts at venues
  • Featured on Setapp: Backtrack Mac was hand-picked and distributed through Setapp's curated Mac app subscription platform — a significant trust and reach signal for quality Mac software

Super Hi-Fi — Streaming SDK

Senior Apple Platforms / SDK Engineer
SDK

Built a custom Swift SDK for online and offline radio streaming — shipped into Peloton across all their stores. Rebuilt the Sonos app from scratch (hardware-free, like Spotify) for a partner proof-of-concept tested by David Byrne. Also shipped CarPlay, AirPlay, and enterprise POC SDKs.

  • Peloton SDK: Built with Swift, Realm, Combine, and Swift Concurrency — full offline radio streaming with track downloads, offline access, and deletion. Shipped and live in all Peloton stores
  • Sonos partnership — full app rebuild: Sonos was a Super Hi-Fi partner and asked us to prove whether their app could be rebuilt from scratch — pixel-perfect animations included — and work without a Sonos device attached (normally required). I built the entire thing: connected it to Sonos private APIs and our own endpoint, with fully working radio and song playback — basically making Sonos accessible like Spotify. The proof-of-concept was tested by David Byrne (Talking Heads). It worked.
  • Enterprise POC integrations: Integrated multiple SDKs into proof-of-concept demos for big tech partners — directly supporting new business development and acquisition conversations
  • CTO architecture team: Active contributor to API design decisions and overall technical project direction
  • Design collaboration: Worked closely with design to implement animations and polish UX beyond what specs described
  • DJ crossfade SDK (iOS layer): Built the iOS SDK for a proprietary engine (C++ core) that matches BPM, crossfades, and loops tracks for seamless radio-style transitions — the technology attracted acquisition interest from both Apple Music and Spotify

FloSports

Senior Apple Platforms Engineer

Engineered athlete-profile and content experiences with Swift, UIKit, and Combine. Built the experimentation and metrics layer that directly fed product decisions — translating streaming platform data into revenue-focused iteration across the iOS app.

  • Athlete profile screens: Rebuilt with performant UIKit components and Combine-driven data binding — smoother, faster, and more maintainable
  • Experimentation layer: Built the A/B testing and analytics infrastructure that fed data directly back into product roadmap decisions
  • Stability work: Bug fixes and codebase improvements across the iOS app, reducing crash rates and improving reliability for live sports viewers
  • Collaborated within a team focused on iterative, data-informed product improvement tied to subscription revenue

Plurall — Somos Educação

Staff iOS Engineer
1M+ users

Led iOS engineering for one of Brazil's largest education apps — 1M+ active users across studying, homework, exams, and offline handouts. Defined architecture, automated delivery with Fastlane, and mentored engineers toward independent, high-quality delivery at scale.

  • Architecture ownership: Defined and enforced patterns adopted across the full iOS team — clear module boundaries, testability, and consistent code quality at scale
  • Fastlane automation: Built lanes that reduced release preparation from days to hours — less manual work, fewer human errors, faster iteration
  • Offline-first content delivery: Built study content and handout delivery that worked without connectivity — critical for Brazilian students in low-coverage areas
  • Mentorship: Grew junior engineers toward senior-level, independent delivery — focused on code review culture and raising the team's overall bar
  • CI/CD + App Store: Owned the full pipeline from branch to production — submission, release notes, review management, and hotfix processes

What I'm great at

Few iOS engineers have shipped real-time audio capture at production scale. At Backtrack, I designed and built the entire AVFoundation recording stack from zero — live capture, segmented export, background-safe recovery, WebSocket sync — and watched it land in rooms at Disney, Topgolf, and HPE. That depth started earlier, at FloSports, engineering corporate-grade streaming pipelines into products people actually love. That combination — broadcast-quality audio and media infrastructure inside beautiful, fast Apple apps — is what I carry into every team. Right now, every AI note-taker, voice product, and real-time tool needs exactly this skillset.
