Hi, This is Elias from Miami. I checked your project description and understand you need a native mobile layer for MyDEAP with AWS Cognito auth, SSE streaming AI chat, document library, audio journal, and settings, built cleanly for iOS (SwiftUI) and Android (Kotlin/Java) using your existing backend and APIs. I’d approach this by structuring the app with MVVM architecture, implementing authentication first, then SSE chat streaming with token rendering, followed by document viewer and journal modules to keep the MVP stable within your 4–5 week timeline. I’ve worked on mobile apps integrating Cognito-based auth, streaming APIs, and document/audio workflows where performance and clean architecture were essential. I’d be happy to review the tender spec and proceed with the technical test. I have a few questions to get a better understanding: Q1 – Are the SSE endpoints already tested on mobile, or should I handle reconnection logic and streaming edge cases from scratch? Q2 – For document uploads and audio recording, do you want offline queuing when connectivity drops? Q3 – Should iOS and Android share consistent UI/UX design guidelines, or do you have platform-specific designs ready? Looking forward to hearing from you.

Hello, I understand that you need a native iOS and Android mobile app development for Phase 1 of MyDEAP. The backend is ready, so my focus will be building the mobile app with clean and reliable code using SwiftUI for iOS and Kotlin/Java for Android. Key features like AWS Cognito authentication, AI chat with live streaming, document library with in-app viewers, and journal audio recordings will be implemented with smooth navigation and secure data handling. I will follow a solid architecture like MVVM and provide test builds regularly, leading up to App Store submission and source code handover. Communication will be clear and timely throughout. To deliver precisely what you want, I need to know: How do you want the app to handle errors during the SSE chat streaming for a smooth user experience? Are there any specific document types or size limits for uploads in the document library? What audio formats and maximum length do you expect for the journal recordings? Do you have a preferred design or UI guidelines to follow for the mobile interface? Will there be specific AWS Cognito user group setups or policies I should follow? How do you prefer handling errors or interruptions during the live AI chat streaming in the app? Thanks,

MVVM ARCHITECTURE: SSE STREAMING & AWS COGNITO NATIVE INTEGRATION Since your backend and SSE endpoints are already live, the priority is a "clean" implementation of the delta event rendering to ensure zero lag chat continuity. At Plan D Studios, we have 12+ years of experience in mobile app development, specializing in Swift/SwiftUI and Kotlin architectures that handle real-time data streaming and secure AWS session management. Technical Execution Strategy: Auth (AWS Cognito): Implementing a robust Amplify SDK wrapper to handle tier aware sessions via cognito:groups, ensuring secure token refreshes and seamless social logins. AI Chat (SSE): Building a reactive SwiftUI/Kotlin observer for your SSE stream. We prioritize token by token rendering with high performance UI updates to keep the "Intelligent/Coaching" modes fluid. Architecture: Utilizing MVVM to decouple the chat logic from the UI, ensuring your source citation cards and follow up suggestions are rendered as distinct, reusable components. Media Handling: Native integration for audio recording and camera scanning, optimized for clean uploads to your transcription endpoints. We handle all iOS Development and Android Development in house. We are ready to take the 2-4 hour technical test to demonstrate our proficiency in SSE streaming and Cognito integration. Shall I review the full tender spec to provide a precise milestone breakdown for Phase 1? Regards, Haider

Interesting project, I will deliver the Phase 1 iOS and Android builds — Cognito auth with social login, SSE streaming chat with token-by-token rendering, document library, and journal with audio recording — all wired to your existing backend and ready for TestFlight within the timeline. For the SSE chat, I will implement a dedicated streaming parser that handles `delta`, `partial_sources`, and `final` events on a background thread, buffering tokens before dispatching to the UI. This prevents dropped frames during fast token bursts and keeps the chat scroll smooth even on older devices. Questions: 1) For the technical test — should Cognito auth target your existing user pool, or a sandbox environment? 2) Are the Android and iOS apps expected to share identical UI designs, or is there flexibility per platform? Looking forward to talking through the details. Kamran
