Overview App Platform: iOS & Android Purpose: A geolocation-based treasure hunt game that encourages users to explore their local community by solving cryptic clues. Users unlock location-based clues and pieces of the "Code" to complete the trail. The app supports both individual and team play, and allows businesses or attractions to create their own custom trails. 1. Core Game Features 1.1 Treasure Hunt Engine • Sequential delivery of cryptic clues. • Each location unlocks the next clue and a unique piece of the "Code." • Completion condition: all code pieces collected in correct order. 1.2 Geo-Fencing Functionality • Geofences define clue-specific physical zones. • Clue unlocks only when user enters correct geofence. • Feedback system for proximity ("You're close!" style hints). • GPS spoofing protection. 2. Game Modes 2.1 Solo Mode • User registers and plays independently. 2.2 Team Mode • Users can create or join a team via invite code or QR code. • Teams share progress and clue unlocking. • Optional in-app team chat. 3. Partner Integration – Event Creation 3.1 Business & Tourist Attraction Dashboard (Web or In-App) • Secure login for hosts. Interface to: • Create and manage events. • Define locations with geofences. • Input custom cryptic clues. • Upload branding assets. • Set event duration, time windows, and participant limits. 3.2 Analytics for Hosts • Participant tracking. • Completion rates. • Engagement stats. • Feedback survey tool. 4. User Features 4.1 User Account System • Profile creation. • Progress saving and sync. • Event history and achievements. 4.2 Map Integration • Clue map view (toggleable hint radius). • Completed trail path view. 4.3 Event Selection Modes Users can browse and select from: • Live Source Code Events (currently running with real-time activity) • Timed Events (complete in a set time window) • Upcoming Events (pre-registration or future events) • Play at Leisure Events (flexible, self-paced mode with no strict time limit) 4.4 Gamification • Badges for milestones. • Leaderboard per event (rank by time or clues solved). • Reward system integration (real world prizes, discount codes, digital vouchers). 5. Notifications & Offline Use 5.1 Push Notifications • New clues. • Team updates. • Event announcements. 5.2 Offline Support (Optional) • Preload event data and maps. 6. Safety & Accessibility • Optional clue skip (limited use per event - Paid Credit Feature ) Accessibility settings: • Text resizing • High contrast mode • Voice-based clue readouts Tech Stack Recommendations (Optional) • Frontend: Flutter or React Native • Backend: Firebase / Node.js with Firestore DB • Maps & Geo: Google Maps API, Mapbox, or OpenStreetMap • Push Notifications: Firebase Cloud Messaging (FCM) or OneSignal Wireframe and assests will be provided .

I need an AI and data analyst programmer who specialises in developing and implementing an academic thesis proposal, which has been approved. The code implementation will include the algorithm, pseudocode, and flowchart for a thesis proposal on AI, blockchain, and IoT using a public dataset. The expert should be capable of providing instruction on the setup and implementation steps in preparation for the thesis defence. 1. Implement an AI-driven algorithm/framework for dynamic resource allocation and optimisation in Edge-IoT ecosystem. 2. Implement a blockchain authentication/verification framework for EC-IoT devices/users, while ensuring data integrity. 3. Evaluate the performance of the proposed interoperable framework using simulations and testbed experiments, benchmarking it against standard baselines across resource efficiency, data integrity, and device security.

PLEASE NOTE: 1. you must have xcode 14 due to the code is so old, check this first before you bid or respond. 2. you must have iphone X/10 or newer but not iphone 16 and you cannot run simulator with this software (too much to explain here) 3. The accepting developer had an old MAC with xcode 14 and it is still not installing and running the code, that is why it is posted again. UPSIDE: if you can do this fast we need to upgrade the code for the app aftervthe bugs are done I have a fully working Flutter app that calls a backend API delivering a dataset across 14 areas. All data is successfully received by Flutter. However, 4 of the 14 areas are not forwarded from Flutter to the native layer. I suspect this is a format of the data in th methodchannel. That was the issue at another point. Backend: working Native modules (iOS + Android): confirmed solid (stable for 2+ years) Flutter → MethodChannel: failing to pass 4 specific areas (10 areas work fine) The Issue - Flutter receives all 14 areas from the API - Only 10 areas are passed to the native layer via MethodChannel - The 4 missing areas are not reaching native, even though structure/format is the same - This is likely a minor Dart-side formatting or dispatch issue Your Task - Investigate the Dart → MethodChannel logic - Confirm the 4 failing areas are properly forwarded - Validate they reach iOS (Swift) and Android (Java/Kotlin) - Fix any Dart-side bugs or mismatches - Keep everything else untouched — the app works well overall Requirements - Senior-level Flutter experience - Deep knowledge of MethodChannel (both iOS and Android sides) - Experience with native integration debugging - Mac with iOS build support (state your Mac model) - Can clone, run, test app end-to-end To Apply Please reply with: 1. Mac model (e.g., MacBook Pro M2, Sonoma) 2. Years of experience in Flutter + Native (iOS & Android) 3. Your MethodChannel experience (examples welcome) 4. Availability (ready to start = great) This is a micro-engagement (1-day task) — ideal for a senior dev who knows native-flutter bridges cold.

I have a website that was built using Squarespace and it is nearly complete. The desktop version is already well-designed. However, I need help refining the mobile version layout to ensure everything appears correctly on mobile devices. Tasks include: Adjusting section alignment, spacing, and image positioning for mobile screens. Correcting overlapping elements and ensuring smooth mobile navigation. Ensuring the desktop version remains unaffected. All work should be performed using the built-in design tools of the platform. Please only apply if you have prior experience working with Squarespace and can share examples of your past work. Looking to get started as soon as possible.
