Project description:
"Build-and-Handover iOS Engineer (Swift/SwiftUI) — Medical Education App
Deliver a production iOS app + Owner Admin Console so the owner controls everything post-launch (no ongoing dev needed).
Features: Animated mascot, daily articles (AI summaries), education modules, MCQ/leaderboard, non-probe ultrasound (speaker+mic, DSP heatmap, educational), non-probe capillaroscope (camera CV), screening tools (DAS-28, etc.), live lectures (Zoom/WebRTC), preliminary AI differential (RAG), subscriptions (StoreKit 2), Arabic/English, RTL, Firebase backend, RheumDB + vector search.
Must-have: SwiftUI, AVAudioEngine + vDSP, CoreImage/Vision, Metal, Firebase (Auth/Firestore/Functions), StoreKit 2, Zoom/WebRTC, PDFKit, EventKit, Lottie, RTL.
Deliverables: Source code, Admin Console, CI/CD, rules, docs, training, credentials, IP assignment, 30–60 day bug-fix warranty.
Share code samples: chirp+FFT, CLAHE/Frangi, Metal compute, StoreKit 2, Firestore rules. Availability: 20–40 h/wk, overlap UTC+3. NDA required.

Must-Have Skills
• iOS: Swift 5+, SwiftUI, Combine/async-await, MVVM; UIKit interop.
• Audio-DSP: AVAudioEngine (play+record), 48 kHz, buffer sync, chirp/tone gen, STFT/FFT (Accelerate/vDSP), basic matched filtering, feature extraction, real-time heatmap drawing.
• Computer Vision: CoreImage, Vision, Metal/MPS; local contrast (CLAHE-equiv), Frangi/Hessian-style filters, morphology, skeletonization, feature metrics; 30–60 fps overlays.
• Payments & Auth: StoreKit 2 subs; Firebase Auth; optional KYC QC (image quality checks).
• Backend (Firebase): Firestore data modeling, rules, Functions, Storage; Remote Config; App Check.
• AI Integration: Call LLMs; RAG basics; vector DB (pgvector/Pinecone) and simple GraphQL client.
• Media/Realtime: Zoom SDK/WebRTC; PDFKit; EventKit.
• Localization: Arabic + English, RTL mirroring & typography.
• Security/Privacy: PHI-safe UX, EXIF stripping, consent gates, signed PDFs.

Nice-to-have: ARKit/SceneKit; React Admin; PostgreSQL; GraphQL; Lottie mastery." (client-provided description)
