Full-Stack macOS & Web Developer - Remote job - Contractor

Objective: Develop Studio-mac, a native macOS application for synchronized video playback (Rytmo band) with ProTools, integrating advanced video card management and web functionalities.

Ideal Candidate Profile Position: Full-Stack macOS & Web Developer

Key Competencies:

Native macOS development (Swift, Objective-C, AVFoundation, Core Animation) C# → Swift Migration: Rytmo band reimplementation on macOS

Video Playback (Clear & DRM), ProTools & Timecode Sync Integration Advanced Video Card Management & 120Hz Video Output Support

Web Development (PHP 8, Laravel, Vue.js, React.js, REST APIs) Performance Optimization & Multi-threading Expertise

Required Experience

5+ years in macOS and web development.

Proven expertise in real-time video/audio synchronization (ProTools, MTC, SMPTE). Proficiency in PHP/JavaScript for web functionalities.

Why This Profile?

This versatile developer will manage the macOS core, optimize video playback, integrate ProTools, and develop web functionalities—ensuring a fully integrated and high-performance Studio-mac application.

Required Skills

macOS Development (Swift & Objective-C)

Languages: Expertise in Swift and Objective-C for native development. Frameworks:

AVFoundation → Video/audio playback and DRM management. Core Animation → Smooth rendering of the Rytmo band.

Cocoa & Interface Builder → Intuitive macOS UI/UX development.

Tools: Xcode, debugging, performance optimization.

C# to macOS Code Migration

Rewrite the Rytmo band algorithm (originally in C#) in Swift for macOS. Port synchronization logic and processing while ensuring precision. Optimize the code for real-time execution on macOS.

Video Playback & DRM Integration

AVPlayer & AVAsset: Handling clear and DRM-protected video playback. DRM Systems (FairPlay, Widevine, PlayReady): Secure video streaming. Formats & Streaming: Support for MP4, MOV, HLS, DASH formats.

Video Card Selection & Management

Detection and selection of the video card:

Implement an interface to choose the video card used for playback (e.g., macOS

GPU, DeckLink, AJA).

Use SDKs (Blackmagic, ...) for advanced video output control.

High Frame Rate Output:

Support for 120Hz playback and external video signal management. Integration with DeckLink cards for professional-grade video output.

Synchronization & ProTools Integration

Timecode Sync (MTC, SMPTE, LTC): Frame-accurate video/audio sync.

ProTools Satellite Protocol: Allowing ProTools to control Studio-mac over the network. MIDI Machine Control (MMC): Alternative transport control (play, stop, seek).

Web Development (PHP & JavaScript)

Backend: PHP 8 / 7 (Laravel, Lumen) → REST API development

Frontend: Proficiency in JavaScript (Vue.js, React.js, Quasar ) for modern and dynamic interfaces.

Multi-threading & Networking

Optimized multi-threading for smooth processing and zero lag.

Network communication:

WebSockets, TCP/IP for real-time interactions with ProTools. API integration to connect with external services.

Testing, Debugging & Optimization

XCTest: Unit and functional testing on macOS.

Advanced Debugging: CPU/GPU profiling, latency corrections.

Real-time Performance Optimization: Smooth playback and perfect sync.
