Project Overview:
We are looking for an expert FlutterFlow Developer / Team to build a high-end cross-platform mobile application (Android & iOS) and a Web Admin Panel for a global-scale project (TITAN X).

Key Requirements:
1. FlutterFlow Expertise: Advanced UI/UX, Firebase backend, custom APIs, state management, and smooth performance.
2. 3D Avatar Integration: Experience integrating 3D models/avatars (GLTF/GLB or WebGL/Three.js/Unity web view) seamlessly inside FlutterFlow.

STRICT WORKING CONDITIONS (NON-NEGOTIABLE):
- Account Access: Work MUST be done directly inside our official FlutterFlow Account from Day 1. No personal account transfers or external file delivery later. We need to track daily live progress inside our workspace.
- Daily Progress: Consistent daily updates and commits are required.
- Payment Milestones: Payments will strictly follow 4 structured milestones based on completed & tested deliverables. Final pricing will be negotiated during discussion.

If you agree to work directly within our FlutterFlow workspace and accept our milestone process, please apply with your portfolio/relevant FlutterFlow & 3D projects.

I want to launch a dedicated matchmaking app that feels as smooth and intuitive as Shaadi.com or Jeevansathi, yet carries its own visual identity. The focus is single-minded: help users discover life partners through verified, information-rich profiles and an intelligent search experience.

Core flow
• Registration and onboarding must include a robust profile-verification step (ID scan, selfie check or comparable method) so every profile carries a “verified” badge.
• Each member can build a detailed profile with multiple photos, lifestyle fields, and partner preferences.
• Advanced search filters—age, religion, community, profession, location, education and any custom tags we add—power the discovery engine. Results should feel instant, with sorting and saved-search options.
• Secure in-app messaging lets matched users chat without exchanging personal numbers. Read receipts, ice-breaker templates and the ability to control who can message are all expected.

Deliverables
1. iOS and Android apps (React Native, Flutter or native—open to recommendations) plus a lightweight admin web portal.
2. Fully documented REST or GraphQL API, ready for future integrations.
3. Database schema supporting scalable profile data, images and match logic.
4. Basic analytics and push-notification hooks (Firebase or equivalent).
5. Source code, build instructions and a short hand-off session.

Acceptance criteria
• User can register, verify, create a profile with at least five photos, apply filters and message a match—all error-free.
• Admin dashboard lists users, flags suspicious accounts, and toggles verification status.
• App passes store review guidelines and installs cleanly on current Android & iOS versions.

If you have shipped similar social or matrimony platforms, especially with large user sets, your insight on scaling and user safety will be invaluable.

-Database Query Refactoring: Eliminate $N+1$ query patterns in catalog fetch calls (e.g., fetchRestaurantSummaries) by denormalizing essential root fields and implementing pagination.
-Asset Optimization: Convert and compress 50MB+ uncompressed image assets (e.g., raw 4K images) to optimized WebP formats to shrink bundle size and reduce startup RAM usage.

4. Architecture & Quality Refactoring:
-Type Safety & Models: Replace untyped Map String, dynamic parameters and raw string literals with strongly typed Dart models (using @freezed or Equatable) and enums.
-State Management & DI: Transition volatile RAM state to persistent local caching (e.g., Hive / SharedPreferences) and introduce proper dependency injection (e.g., get_it or Riverpod).
-Clean Up & Testing: Remove dead code/seed scripts from production binaries and set up a basic automated test suite (test/) covering core calculations.

*Required Skills & Qualifications:
-Flutter / Dart Expertise: 4+ years of deep experience building and refactoring complex, production-grade Flutter apps.
-Firebase Master: Hands-on experience with Firestore Security Rules, Cloud Functions (Node.js/TypeScript), FCM, APNS token lifecycle, and performance monitoring.
-Payment Gateways: Experience integrating webhook-verified payment gateways (Moyasar, Stripe, or similar).
-Native Android & iOS: Solid understanding of build.gradle.kts release signing/R8, Info.plist permission configurations, and native build troubleshooting.
-Clean Code & Architecture: Strong knowledge of Clean Architecture, SOLID principles, Dependency Injection, and modern state management (Riverpod, BLoC, or Provider).

We're excited to work with a talented App Developer who can bring this AI-powered mobile app to life!

I’m looking for an experienced full-stack developer to help improve an existing React Native mobile app and build a modern web platform for the same product.

The mobile app is already live on the App Store, and I’m looking to modernize the UI/UX, improve the overall user experience, and add new features over time. Alongside the app, I need a responsive website where users can learn about the platform, create accounts, subscribe, and manage their information through a secure dashboard.

The platform is focused on amateur basketball leagues and will continue to grow, so I’m looking for someone who can build with scalability and maintainability in mind rather than simply delivering a one-time project.

I’m looking for a developer who:

* Has strong experience with React Native and modern web development
* Is comfortable working with Firebase and subscription-based applications
* Writes clean, scalable, well-documented code
* Uses modern AI development tools (such as Cursor, Claude, GitHub Copilot, etc.) to work efficiently
* Can communicate clearly and contribute to technical decisions

This has the potential to become a long-term working relationship as the platform continues to expand. My goal is to find someone who can initially build the next phase of the product and potentially continue as the technical lead as we grow.

We are looking for an experienced Computer Vision / AI developer (or team) to build a scalable, on-premise employee attendance and tracking platform using NVIDIA DeepStream or Savant Framework (DeepStream preferred). The system will use CCTV cameras for face recognition, person re-identification (ReID), and multi-camera tracking to automatically record attendance, monitor employee movements, and detect when employees leave or return to their assigned work areas.

The platform must include a modern web-based Admin and Supervisor dashboard to manage employees, upload multiple face images, configure unlimited cameras, buildings and floors, upload floor plans, place cameras on maps, create work zones (geofencing), and display employees' real-time locations on a 2D floor plan. It should be designed as a universal, modular solution that can be deployed in different environments and scale to any number of cameras or employees.

Please apply only if you have proven experience with NVIDIA DeepStream/Savant, multi-camera tracking, face recognition, and modern web dashboard development. Share examples of similar AI/computer vision projects you have completed.

Branching support:
Child splines attached to parent splines
Attachment point defined parametrically (0–1 along parent spline)
Branches can slide along the parent spline in real time
Independent scale and rotation per branch
Important Scope Clarification

Branches do NOT require watertight mesh fusion.

This is a visual creation tool, not a CAD or 3D-printing application. Simple overlapping geometry (or overlap hidden with decorative assets) is completely acceptable.

No metaballs, voxel remeshing, or topology reconstruction is required.

2. Touch Interaction

Users should be able to:

Draw curves using Apple Pencil
Move spline nodes
Rotate cross sections
Adjust local thickness
Add and remove nodes
Create and edit branches

The interaction should feel responsive and optimized for iPad.

Hoi!
Ik ben op zoek naar een ervaren FlutterFlow-developer die mij kan helpen met het afronden van een app waar ik momenteel aan werk.
Ik heb al een FlutterFlow-project waarin de basis van de schermen grotendeels is gegenereerd met AI. De opzet staat dus al, maar ik zoek iemand die de technische kant goed kan neerzetten en de app werkend maakt.
De werkzaamheden bestaan onder andere uit:
Inloggen en registreren
Firebase-koppeling
Database opzetten
Gegevens van gebruikers opslaan en beheren
Pushnotificaties op basis van opgeslagen gegevens
Een nette en schaalbare structuur binnen FlutterFlow
Ik zoek iemand met ervaring in zowel FlutterFlow als Firebase, die alles bouwt binnen mijn eigen FlutterFlow-project, zodat ik later zelf ook aanpassingen kan doen en de app kan uitbreiden.
Het gaat om een relatief eenvoudige app. Ik ben vooral op zoek naar iemand die een goede technische basis kan neerzetten. Als de samenwerking goed bevalt, is er mogelijk ook vervolgwerk voor toekomstige uitbreidingen.

Ik kijk uit naar je reactie!
