Work
Backtrack — iOS
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
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
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
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
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
An app studio — shipped 25+ iOS apps to the App Store across industries. The foundation behind the 30+ number.
