Discover Projects with 'Firebase' Expertise

Design a responsive website + mobile-first web app for asset inventory and inspections using RFID tags. Each physical asset is registered in the system and linked to a unique RFID identifier. The primary workflow is: scan RFID with a phone → auto-load the asset record → complete an inspection → status updates instantly on a live dashboard.

1) Users and Roles

Create role-based access with permissions:
• Admin: manage users, locations, question templates, RFID linking, reporting
• Supervisor/Manager: view dashboards, assign inspections, review history, export reports
• Inspector/Employee: scan RFID, complete inspections, view assigned tasks and prior inspections (read-only)

Authentication: email + password (optional SSO later). Tie every inspection to a logged-in user.

2) Core Objects and Data Model

Design the data structure and UI around:
• Assets
• Asset ID, name/type, make/model/serial, location, department/LOB, photos, notes
• RFID UID (unique), RFID status (active/lost/replaced)
• Current condition status: Inspected-OK / Not Inspected / Out of Service
• Last inspection timestamp, next due date
• Inspections
• Inspection ID, asset ID, user ID, date/time, location (manual + optional GPS)
• Question set version, responses, comments, photos, signature.
• Final result: OK or Out of Service
• Questions / Templates, Inspection questions specific to type of asset. (Fire extinguisher, car, van, ladder, baggage cart, etc.)
• Question text, type (yes/no, pass/fail, multiple choice, numeric, text)
• Required vs optional, conditional logic (if fail → require comment/photo)
• Users
• Name, employee number, email, role, station/location assignment

3) RFID Scan Flow (Mobile Web App)

Design the mobile workflow for speed and minimal taps:
1. User opens the web app and taps “Scan RFID”
2. Phone reads RFID (NFC) and captures the RFID UID
3. System looks up the linked asset
• If found: auto-populate asset details and display an Inspection Form
• If not found: show “RFID not recognized” with an option (Admin only) to link it
4. Inspection page displays:
• Asset summary card (photo, name, location, last status)
• Inspector details auto-filled (name, employee ID, timestamp)
• Checklist/questions (from template based on asset type)
• Quick buttons: Mark OK or Out of Service
• If Out of Service: require reason + photo + optional notes
5. On submit: write the inspection record and update asset’s current status instantly.

4) Live Website Dashboard (Desktop + Mobile)

Create a real-time dashboard that shows asset compliance and condition:
• Status tiles:
• Inspected (OK)
• Not Inspected
• Out of Service
• Filters:
• Location, asset type, department/LOB, date range, assigned team, inspector
• Table/grid view:
• Asset name, RFID, location, status, last inspected, inspected by, notes, photo icon
• Drill-down asset page:
• Full asset profile + inspection history timeline
• Downloadable inspection reports (PDF export optional)
• Visualizations:
• Bar chart by location or asset type
• “Overdue / due soon” list (optional scheduling)

Ensure the dashboard updates instantly after inspections (websockets or realtime polling).

5) Required Screens / Pages (Deliver as a clickable prototype plan)
• Public: Login / Forgot Password
• Admin: User Management, Asset Management, RFID Linking, Question Template Builder
• Inspector: Scan RFID, Inspection Form, “My Recent Inspections”
• Dashboard: Live Status Board, Filters, Asset Detail, Reports/Exports
• System: Error states (offline mode, RFID not found, permission denied)

6) UX/UI Requirements
• Clean, modern, aviation/industrial-friendly design (high contrast, large tap targets)
• Fast mobile inspection flow (scan → inspect → submit in under 30 seconds)
• Clear status colors and labels (include accessible text labels, not color-only)
• Support photo capture from phone camera
• Optional: offline mode (store drafts locally, sync when back online)

7) Technical Expectations (High-Level)

Provide:
• Suggested tech stack (e.g., React/Next.js + Node/Nest + PostgreSQL; or similar)
• Realtime update approach (websocket/service like Firebase/Supabase or server websockets)
• Security basics (RBAC, audit log, encryption in transit, least-privilege)
• API endpoints list (assets, inspections, templates, users, RFID lookup)
• Database schema outline

8) Acceptance Criteria
• Scanning an RFID on a phone loads the correct asset and pre-fills inspector details
• Submitting inspection updates the asset status immediately
• Dashboard reflects Inspected / Not Inspected / Out of Service accurately with filters
• Full inspection history is retained and exportable
• Admin can create assets, link/replace RFIDs, and build templates per asset type

Deliver the output as:
1. sitemap + user flows,
2. UI wireframes (low-fidelity),
3. component list/design system,
4. data model + API outline,
5. short implementation plan.

Tech Stack
- Frontend: React Native (latest stable, with TypeScript for type safety)
- State Management: React Hook Form + Zod for forms/validation, TanStack Query for data fetching/caching
- UI: Tailwind CSS + shadcn/ui components (adapted for RN via libraries like NativeWind)
- Backend: Supabase (Postgres DB with RLS for security, Auth for user management, Realtime subscriptions for live updates, Storage for file uploads, Edge Functions for serverless logic)
- Mobile-Specific: Expo for easier dev/build (if compatible) or bare RN workflow; focus on iOS/Android cross-platform
- Other: date-fns for dates, Recharts for charts/trends, Lucide icons, jsPDF for exports/reports
- Version Control: GitHub
- Testing: Jest + React Native Testing Library; aim for 80%+ coverage on new features
- Deployment: App Store/Play Store via Expo EAS or manual; CI/CD with GitHub Actions

Scope of Work
1. **Food/Nutrition Lookup (Barcode Scanning, Camera Photo Recognition, Recipe Link Parsing → Net Carbs Calculation)**
- Build a seamless nutrition entry flow in the patient app: users scan barcodes (via react-native-vision-camera or similar), take photos of food labels/packages (OCR via MLKit or Tesseract.js), or paste recipe links (parse via web scraping or API like Spoonacular/Edamam – integrate if needed, but prefer open-source/offline-capable for privacy).
- Output: Extract nutrition facts (calories, carbs, fiber, sugars, etc.) and auto-calculate net carbs (total carbs - fiber - sugar alcohols). Integrate with insulin calculator (e.g., suggest bolus based on carbs).
- Edge cases: Handle poor lighting/blurry scans, offline mode (cache common foods), multi-item meals, custom user overrides.
- UI: Modal scanner/camera view, results preview with edit fields, save to meal log (Supabase insert with RLS).

2. **CGM/Device Integrations + Home-Screen Glucose Widget**
- Integrate with popular CGMs (e.g., Dexcom G7 via API/OAuth, FreeStyle Libre via SDK – focus on read-only glucose pulls; use react-native libraries like dexcom-share or). Pull real-time glucose data, trends, and alerts.
- Build a home-screen widget (Android Widget/ iOS Widget Extension via RN libs like react-native-widgets): show current glucose, trend arrow, low/high alerts. Sync via Supabase Realtime or local storage for offline.
- Edge cases: Permission handling, battery optimization, data refresh intervals (e.g., 5-min), error states (disconnected device). Ensure HIPAA-safe (no unencrypted storage).
- UI: In-app dashboard integration + widget preview/setup flow.

3. **Caregiver Access/Sharing**
- Implement role-based sharing: patients grant access to caregivers (family/friends) for view-only or limited edit (e.g., view glucose logs, receive low/high alerts, send messages). Use Supabase Auth + RLS to enforce (e.g., shared_access table linking user_ids with permissions).
- Flows: Invite via email/SMS (Supabase Auth invite), accept/revoke access, shared dashboard view (filtered data). Push notifications for alerts (via Expo Notifications or Firebase).
- Edge cases: Multi-caregiver support, permission granularity (e.g., hide notes but show glucose), audit logs for changes.
- UI: Settings tab for managing caregivers, shared view with read-only components.

4. **Community Features**
- Build moderated community spaces: forums/groups for patients (e.g., "T1D Tips", "Recipe Shares") with posts, replies, likes, reports. Use Supabase tables (posts, comments, likes) with Realtime for live updates. Moderate via admin flags or AI (e.g., integrate OpenAI moderation if needed).
- Include anonymity options, search/filter, notifications for replies/mentions. Tie into rewards (e.g., points for helpful posts).
- Edge cases: Spam prevention (rate limits, captcha), offline caching, accessibility (ARIA for RN). Ensure no PHI sharing (content rules + auto-masking).
- UI: Tabbed community screen with infinite scroll, post composer, profile badges.

5. **General Bug Fixes & Polish**
- Audit/fix existing bugs (e.g., UI glitches, data sync issues, performance on low-end devices). Polish UX: animations (e.g., Lottie), dark mode, offline support (via TanStack Query caching), accessibility (VoiceOver/TalkBack). Optimize for battery/data usage.
- Run full app tests (unit, integration, E2E via Detox/Appium if set up).

I need a Flutter developer to assist with two specific tasks:

1. Generate a signed Android APK from my current Flutter source code.
2. Build and upload an iOS version to TestFlight using my Apple Developer account.

I will provide:
- GitHub access to the Flutter source code
- Access to my App Store Connect account for TestFlight upload

Scope of this milestone:
- No feature development
- No UI changes
- No bug fixing
- Build and upload only

Deliverables:
- Working Android APK
- TestFlight build successfully uploaded and visible in my App Store Connect account

Please note:
This is the first milestone only.
Future tasks (such as bug fixes) will be discussed and contracted separately when this step is completed successfully.

Context
We have a FlutterFlow app using Firestore for a quiz system.

Each quiz question creates a quizResponses document with:
• quizRef
• questionRef
• questionIndex
• selectedOptionIndex
• status

The quiz-taking flow works and data is written correctly.

Problem
The Answer Review page does not reliably display the correct selected answer per question.

Symptoms:
• Review cards sometimes show the same answer text for multiple questions.
• Answer text resolves incorrectly even though selectedOptionIndex differs.
• UI currently relies on resolving answer text via questions.options[selectedOptionIndex], which is proving brittle.
• Attempts to fetch the related questions document at runtime (via Firestore queries) have caused inconsistent results and regressions.

Constraints / Requirements
• Exactly one quizResponses document per question (already enforced).
• Review page must be stable (no navigation back to quiz).
• Fix must not break the existing quiz flow.
• Preference is for data correctness over clever UI binding.
• Open to schema changes (e.g. storing selected answer text) if justified.

Tech Stack
• FlutterFlow
• Firebase Firestore
• No custom backend code (FlutterFlow actions only)

What I need
Someone experienced with FlutterFlow + Firestore data modelling to:
• Diagnose why review bindings are unstable
• Propose the correct data flow
• Implement a robust fix (ideally minimal UI refactor)

We are looking for a skilled developer to create a no-frills local events application based on provided specifications. The app will feature a feed, map integration, user profiles, and quick hosting functionalities. Candidates should have experience with React Native and Firebase, and must prioritize clean, fast, and efficient coding. If you are detail-oriented and can deliver high-quality work within a set timeline, we want to hear from you!

• Include a link to your GitHub profile and/or website
• What frameworks have you worked with?
• Please list any certifications related to this project
• Describe your approach to testing and improving QA
• Describe your recent experience with similar projects

Mobile application is in its final stages. We are offering a permanent front end development position for 3 hours a day / 5 days a week for $550 a month. The front end code is written mostly in Flutter with some Swift. Applicants need to be very experienced in Flutter, Swift, Apple App Store, Google Play Store, Xcode and Android build.

I need a clean, fast iOS app whose main purpose is real-time messaging between users. Everything should feel native to the Apple ecosystem, so please build in Swift or SwiftUI and make sure it passes App Store review guidelines.

Core scope
• User registration/login (Apple ID or email)
• One-to-one chat with text, images, and read receipts
• Secure data storage in the cloud (Firebase, Supabase, or a comparable solution)
• Basic admin panel to manage users and moderate content
• Thorough testing on the latest iPhone and iPad devices

I am focusing only on messaging for the first release; payments or push notifications can wait until a future milestone, so keep the architecture modular enough to add those later without a full rewrite.

Deliverable is an Xcode project, backend configuration guide, and a TestFlight build ready for my review. Once everything works smoothly and I approve the TestFlight build, we can wrap up this phase and discuss follow-on features.

I have an existing mobile app (Flutter / React Native/different ones) that is approximately 80% complete. The core features, screens, and logic are built, but the app is not currently running end-to-end. I’m looking for a senior mobile developer to do a live screen-share consultation with me to review the codebase and give a clear, honest assessment of what’s needed to get the app running on iOS (and into TestFlight if feasible).

Two developers have already reviewed the project and estimated around 8–9 hours to get it fully up and running. I’m looking for one more experienced opinion before moving forward.

This is consultation only at first (no fixes during this session): review the code live, identify blockers, and provide a realistic estimate for time and cost.

An NDA will be required before the session. If we work well together, there is a strong possibility of bringing you on for additional paid work beyond this consult. I’m looking for someone who is authentic, straightforward, and experienced—not salesy, not overpromising—just clear, honest guidance from someone who has actually shipped iOS apps.

Please apply only if you have real experience debugging mobile builds, working with Firebase, and taking apps from “almost there” to live.

• Please list any certifications related to this project
• Include a link to your GitHub profile and/or website
• Describe your approach to testing and improving QA
• Describe your recent experience with similar projects

Most of the screens and core logic of my FlutterFlow app are already in place; what’s missing is the solid, production-ready plumbing. I need someone who lives and breathes FlutterFlow, Firebase and Dart to step in, tie everything together, and make the build store-ready.

Here is what remains:

• Backend integration – The local state is working, but I still have to connect everything to Firebase properly. That includes creating the cloud Firestore structure, final indexing rules, and any remaining collections needed for production analytics.
• Database setup – Migrate the current test data into its new schema, seed the initial data, and verify reads/writes from the app are efficient and secure.
• API integration – I already have REST endpoints documented; your task is to wire them in FlutterFlow with proper error handling, caching where sensible, and unit tests for the critical calls.
• Payments flow – The in-app purchase / subscription screen is designed, but the logic is only halfway done. You’ll finish the end-to-end payment flow (webhooks, validation, error states).
• Bug fixing – A handful of UI glitches and state issues remain; you’ll track them down, resolve them, and push clean, commented commits.
• Firebase cleanup – Remove obsolete functions, tighten rules, set up proper environments (dev, staging, prod) and confirm that analytics/events still fire.

Deliverables:
1. Updated FlutterFlow project file with all integrations complete.
2. Clean Firebase project (FireStore, Authentication, Functions) that mirrors the implemented logic.
3. Working payments flow verified in both sandbox and production modes.
4. Short hand-off document outlining architecture choices and steps to add future features.

If you have recent examples of FlutterFlow builds that are live in the stores and can jump onto a quick hand-over call, you’re exactly who I’m after. I’m ready to give you access to the repo and Firebase project as soon as we agree.

Skills: PHP, Mobile App Development, iPhone, MySQL, Dart, Backend Development, Database Management, API Integration

Current Platform the system includes:
* A **client dashboard** where each business logs in and manages its items/content
* A **separate public-facing project** that displays each client’s items via their own URL
* A **multi-tenant architecture** (many clients, isolated data)
* Production database and real users

I already have clients using the platform and more waiting, so I need someone dependable for ongoing work.

Tech Stack (Must Have Experience)

* React + Vite
* TypeScript
* **Supabase** (PostgreSQL, Auth, Storage, RLS)
* Git + GitHub
* Vercel deployment

Supabase knowledge is critical.


Main Work Needed

1. Database Security & Scalability (Supabase)
* Review and improve the current database structure
* Ensure proper **Row Level Security (RLS)** policies
* Guarantee strict **data isolation between clients (multi-tenant security)**
* Improve relationships, indexing, and performance
* Prepare the system to scale as the number of clients grows

I need someone who understands SaaS database design, not just basic CRUD.


2. Dashboard Improvements (Design Controls)

Enhance the client dashboard by adding:
* More **design customization options** (colors, visual styles)
* One additional **frontend template** clients can select for their public page
* Can be a simple showcase-style layout

This involves both dashboard UI and frontend template logic.

3. Payments (Optional Per Client)

Some clients will accept orders, others will not.

We need to:
* Add a **database flag per client** to enable/disable payments
* Activate ordering and payment flow only if enabled
* Integrate this payment API:
[https://grow-il.readme.io/](https://grow-il.readme.io/)

If disabled → display only
If enabled → ordering + payments active


What I’m Looking For

* Strong React + TypeScript skills
* Solid Supabase and PostgreSQL experience
* Experience with SaaS or multi-tenant systems
* Ability to work with an existing codebase
* Good communication and reliability
* Interested in **long-term collaboration**


This project is ongoing. I prefer a strong long-term developer over the cheapest option.

I am building an MVP mobile-friendly web app (not native) where users record one minute of video per day as a private journal. The app uploads the video, transcribes the audio, and (for subscription users) uses an LLM to generate structured written feedback (goal coaching, encouragement, reflection prompts). Core features: authentication, daily recorder with timer, upload to cloud storage, transcription, AI feedback response, journal timeline, collage view (compare last week/month), save/delete entries. Non-goals for MVP: public sharing, advanced video emotion analysis, real-time feedback, full moderation system.

Requirements: experience with video uploads/storage (Supabase/Firebase/AWS), speech-to-text pipelines (Whisper/OpenAI or Google), LLM APIs, and production-ready auth. Please share examples of similar work.

Budget: $3,000 total ($2,500 dev + $500 buffer)

Timeline: 4-6 weeks

Important: app is 13+ and private by default; include delete flows and privacy safeguards.

Note: There is already a GITHUB and a working example deployed to firebase.
This needs refinement, design, and to ensure functionality is all there.

I’m building a web app that lets teachers spark instant participation in class and track engagement in real time. The core of the product is a live quiz engine, but I also want a toolbox of quick-fire activities—buzzers for fastest-finger questions, one-click polls, a randomizer, dice roll, coin flip and an “energy meter” that shows how many students are still actively responding.

Teachers must be able to create or import questions, launch an activity from any device, and watch results update instantly on a shared screen. Students will join through a short URL or QR code; no full account sign-up for them, just a name entry so the session stays quick.

The interface has to feel equally natural on desktop and mobile, with smooth transitions when a teacher moves from their laptop to the classroom smartboard or phone. I’m open on the tech stack, though something modern and component-based (React, Vue, Svelte, or similar) on the front end and a lightweight Node, Django or Laravel back end makes sense to me—feel free to pitch alternatives if you can meet the same performance goals.

Deliverables
• Responsive web app covering all tools listed above
• Teacher dashboard for session setup, question banks and result history
• Live student view with real-time updates (<200 ms latency target)
• Simple deployment guide and documented codebase

I’ll review the project on-screen: if every activity runs fluidly, results record correctly and the UI adapts cleanly between desktop and mobile, we’re good to go.

Skills: PHP, JavaScript, Mobile App Development, Android, Django, Node.js, Laravel, Web Development, Vue.js, Svelte

We are building a home services booking mobile application from scratch and are looking for a senior Flutter developer who has experience delivering production-ready apps.

• What challenges do you foresee with Apple/Google approval for in-app purchases, and how would you address them?
• Have you designed or implemented the UX/UI for Flutter apps before? Please share examples of apps you’ve built that you consider visually appealing, and describe how you approached the design (custom UI vs. using existing components).

We are looking for an experienced Flutter engineer to build a production-ready offline-first
mobile application for both iOS and Android. This project focuses on Mobile App Development
fundamentals such as data persistence, synchronization strategies, and clean cross-platform
architecture.
The application must work reliably without an internet connection, store data locally on the
device, and intelligently sync changes once connectivity is restored. Handling edge cases like
data conflicts, partial sync, and state recovery is a key part of this role.
This is a strong portfolio project demonstrating Flutter Mobile App Development, iOS
Development, and Android Development beyond simple API-driven apps

Platforms: Android (Kotlin) or Flutter (Dart)
🔍 Project Overview
I’m looking for an experienced mobile developer to create a registration page for my app.
This is a confession app for which I am doing user research but I want to kickstart it with a registration page. Android first or flutter would also work.
Splash Screen
Email/username registration
Firebase Authentication

Saya ingin membangun sebuah aplikasi seluler khusus untuk platform Android. Mohon bantu saya dari tahap perencanaan sederhana hingga aplikasi siap pakai di Google Play Store.

Ruang lingkup pekerjaan:
• Merumuskan fitur inti dan alur pengguna (UI/UX dasar).
• Membangun kode sumber Android—boleh memakai Kotlin atau Java di Android Studio.
• Menghubungkan backend ringan (REST API atau Firebase) untuk penyimpanan data dan autentikasi.
• Menyiapkan ikon, splash screen, serta file APK/Bundle final.
• Menjelaskan langkah‐langkah build dan publish agar saya bisa memeliharanya di kemudian hari.

Saya terbuka mendiskusikan detail fitur, timeline, dan teknis lainnya. Silakan sertakan portofolio aplikasi Android yang pernah Anda kerjakan dan sebutkan stack teknologi yang Anda kuasai.

Skills: PHP, Java, Mobile App Development, Android, Kotlin, Android App Development, Android Studio, REST API

I need an Android application that lets end-users purchase a local virtual number and instantly configure it from their phone. Inside the app the user must be able to set up call forwarding, manage voicemail greetings and messages, and send/receive SMS—all tied to the same newly purchased local number.

The flow I have in mind is straightforward: after sign-up, the user browses available local numbers (pulled from a telecom API such as Twilio, Plivo, Telnyx or a comparable SIP provider), buys one, and then sees three configuration screens—Call Forwarding, Voicemail. Changes should apply in real time via the provider’s REST endpoints or SIP signalling.

Please build the client in Kotlin, follow an MVVM structure, and use native Android components (no WebView shortcuts). A lightweight back-end or Firebase layer can hold user accounts, number inventory, and billing tokens; feel free to propose what you prefer, as long as it is documented.

Finally, App must be submitted on Google Play Store according to policies and must be made live.


Deliverables
• Complete Android Studio project with source code
• README covering provider setup, API keys, and steps to enable forwarding, voicemail and SMS
• Release-ready APK for testing
• Playstore Submission


Acceptance criteria
• A local number can be purchased from the app without leaving the flow
• Incoming calls ring through the VoIP stack in under one second
• Call forwarding, voicemail playback, and two-way SMS all function reliably on that number
• App runs crash-free on Android 8 through 14 and meets Google Play call/SMS permission policies

If you have shipped VoIP or SIP apps before and can hit the above targets, I look forward to your proposal.

Skills: Java, Mobile App Development, Android, VoIP, Kotlin, Twilio, Android App Development, SIP, Plivo, REST API

Capacitor Mobile Developer - Sports Fixtures App (iOS + Android Launch)
About the Project
We're building a global sports fixtures platform and a social widget destination website, and need an experienced Capacitor developer to join our small team. Our Progressive Web Apps are already built using Next.js 16, and we have a full-time backend developer working alongside you.
Your main focus is wrapping our existing web apps in Capacitor, adding native features, handling frontend development work, and successfully submitting and getting approved 4 apps total: 2 iOS apps and 2 Android apps for our sports fixtures platform and social widget destination.
What You'll Deliver
4 apps - 2 for the App Store (iOS) and 2 for the Play Store (Android). All 4 apps must be successfully submitted and approved, not just submitted.
You'll be building apps for two distinct platforms:

Sports Fixtures Platform (iOS + Android)
Social Widget / Destination Website (iOS + Android)

Beyond the mobile apps, you'll also handle frontend development work. This includes building from design files we provide or polishing and refining AI-generated code (vibe coded components) that we'll give you to perfect.
The apps will include multi-provider authentication through Firebase (Apple, Google, Facebook, and Email), native features like push notifications, deep linking, and share functionality, converted Next.js server actions to API routes, and integrated social widgets and sports data APIs.
Our PWAs are approximately 75% complete with most UI components built and a finalized design system. Our backend developer handles the bulk of API work, though we're a team and everyone pitches in when needed.
Required Experience
At least 3 years of Capacitor development with a proven track record of successfully approved apps in both the App Store and Play Store. You must provide working links to apps you've shipped to both platforms.
Strong Next.js and React frontend development skills - you'll be building and polishing UI components, not just wrapping existing code. Experience working with design files and refining AI-generated code is valuable.
Expert-level Next.js knowledge, particularly with App Router, server actions, and API routes. Experience implementing Firebase Authentication with multiple providers.
Deep knowledge of iOS code signing, provisioning profiles, TestFlight, and App Store Connect. Android experience with keystore management, Play Console, and production releases.
Most importantly, you should have successfully navigated App Store Review and understand how to avoid common rejections, especially Guideline 4.2.
Bonus points for experience with sports or live data apps, social media integration, real-time features, and PWA optimization.
Your Main Responsibilities
Your primary focus will be:
Mobile Development: Developing and submitting 2 iOS apps and 2 Android apps (sports fixtures platform + social widget destination), and seeing all 4 through to successful approval in their respective stores.
Frontend Development: Building new frontend components from design files and polishing AI-generated (vibe coded) components we provide. This includes implementing pixel-perfect designs, ensuring responsive behavior, and maintaining code quality.
Integration Work: Implementing the authentication system, setting up push notifications and deep linking, and integrating with the API endpoints.
Store Success: Preparing store assets for all apps and handling review feedback until all 4 apps are approved and live.
While our backend developer handles most of the API and infrastructure work, we're a collaborative team. If you need to jump in and help debug an API issue or the backend dev needs a hand testing something, we all work together to get it done.
Team Structure
You'll work closely with our full-time backend developer and report directly to the founder who serves as project manager. We're a small, tight-knit team that values quick decisions, open communication, and helping each other out when needed.
Tech Stack
Frontend: Next.js 16, React 19, TypeScript, Tailwind CSS, shadcn/ui, Capacitor
Backend: Next.js API routes, Firebase Auth, TheSportsDB API
Tools: Git/GitHub, TestFlight, Play Console, Figma (for designs)
How to Apply
We'd love to hear from you if you can include these four things:
Portfolio Links: Share links to Capacitor apps you've successfully shipped to both the App Store and Play Store. Also share examples of frontend work you've built - component libraries, polished UIs, or anything that shows your frontend development skills.
Technical Questions: Help us understand your thinking on these:

Our app uses Next.js server actions. How would you architect this for Capacitor and why?
We're implementing Apple, Google, Facebook, and Email sign-in. What's the critical iOS requirement when offering Google or Facebook auth?
What are three reasons Capacitor apps get rejected under Guideline 4.2, and how would you prevent them?

Availability: Can you work full-time on this project? What timezone are you in?
Experience: How many Capacitor apps have you shipped total? Any sports or live data experience? Have you worked with an existing backend team before? Are you comfortable building from design files and polishing AI-generated code?
What We're Looking For
We want someone who shows their work through real examples, not just general claims. Someone who's collaborative and comfortable working as part of a small team where everyone helps each other out.
You should be confident navigating both app stores and know how to build apps that feel native, not just wrapped websites. You should also be a strong frontend developer who can take designs and turn them into polished, production-ready code, or take AI-generated components and refine them to perfection.
We're not looking for generic proposals, React Native developers (different framework), or folks who've only shipped to one platform.
What Success Looks Like
4 apps successfully submitted and approved - 2 in the App Store and 2 in the Play Store (sports fixtures + social widget). Apps that feel polished and native with authentication working smoothly across all providers, native features integrated properly, and clean store submissions that pass review.
Frontend work that's pixel-perfect - whether built from designs or polished from AI-generated code, the UI should be production-ready, responsive, and maintainable.
Beyond the technical stuff, success means being a great team player, communicating well, and helping us all move forward together.
Why You'll Enjoy This
You get to focus on what you do best - building great mobile apps and polished frontend experiences - while our backend developer handles the API heavy lifting. When you need something, you talk directly to the founder - no layers of management or waiting for decisions.
Our codebase is clean and modern. The scope is clear with no scope creep. And you'll be launching something real that sports fans around the world will actually use, plus a social widget platform that brings people together.
Plus, we're a friendly team that values collaboration over egos. We help each other out and celebrate wins together.
About Us
We're building a global sports platform with time-zone accurate fixtures, TV listings, tickets, and venue finding, alongside a social widget destination that creates community. Small team with a move-fast culture where everyone's input matters and we support each other to get things done.
Compensation
We pay competitive rates based on your experience, structured around project milestones. Let's discuss specifics when we talk.
Next Steps
Take a look at our live PWA at https://sportsfixtures-pwa.up.railway.app/onboarding to see what we've built.
Prepare your portfolio links for both stores and frontend work examples, think through the technical questions, and tell us a bit about yourself.
The applications that stand out show specific examples, explain real challenges you've solved, and demonstrate genuine interest in what we're building.
Ready to join our team and help us get all 4 apps live and approved? We'd love to hear from you.

I need a lightweight, responsive web page that can display live scores for any sport I configure, together with a running event timeline. Because all updates will be keyed in by an on-site admin, the interface for entering scores must be as quick and fool-proof as the public view is polished.

Core flow
• An admin logs in from a tablet or laptop, hits a simple “+ / –” or text field, and the change pushes instantly to every viewer’s screen—no page refresh.

• The public page shows current score, the game clock, and a chronological timeline of goals, fouls, substitutions, or other highlights that the admin tags while the match unfolds.

Key requirements
– Real-time score updates driven by manual input (WebSocket, Firebase, or your preferred real-time tech).
– Clean, mobile-first UI that adapts easily to football, basketball, tennis, or any custom labels I feed it.
– Discrete admin panel (password protected) with undo/edit for mistaken entries.
– Event timeline auto-scrolling and time-stamped.
– Deployable as a single-page app I can drop onto standard hosting (HTML5/CSS/JavaScript stack or React/Node—your call, just document setup).

Deliverables
• Source code in a Git repo.
• One-click build/deploy instructions.
• Brief user guide for the match-day admin.

I value clear commits and concise documentation over fancy visuals, so feel free to start with a minimal design system and iterate. Let me know which tech stack you propose and any past live-data work you can point me to, and we’ll kick off right away.

Skills: JavaScript, Website Design, CSS, User Interface / IA, HTML5, HTML, Node.js, Git, Web Development, Documentation

I’m looking for a FlutterFlow developer with iOS publishing experience to help me publish my app to TestFlight.
The app is already completed in FlutterFlow.
This is not a feature or UI task — it’s a final iOS signing/publishing fix.

FlutterFlow iOS build fails with the error:
“Signing for ImageNotification requires a development team”
This is related to the Notification Service Extension (ImageNotification), a known FlutterFlow iOS edge case.
All Apple-side setup is already completed:
App ID configured


Push Notifications enabled


Associated Domains enabled


App Store provisioning profile created


App Store Connect API key already added in FlutterFlow



What I Need
You can solve this using any reliable method, for example:
Option A (preferred & fastest):
Export FlutterFlow project


Open in Xcode


Assign Apple Team ID to:


Runner target


ImageNotification extension


Archive and upload to TestFlight


OR
Option B:
Fix directly in FlutterFlow if you have a proven workaround


Successfully generate a TestFlight build



Deliverables
App successfully uploaded to TestFlight


Build visible in App Store Connect


No changes to app functionality or UI



Requirements
Please apply only if you:
Have real experience with FlutterFlow iOS publishing


Understand iOS signing, provisioning, and extensions


Can work confidently with Xcode if required



Budget & Timeline
💰 Budget: $10 USD (fixed)


⏱ Delivery: Within 24 hours


This is a small, targeted task for someone experienced.

To Apply
Please include:
Your FlutterFlow + iOS publishing experience


Whether you’ll use Xcode export or FlutterFlow-only approach


One example of a FlutterFlow app you’ve published (TestFlight or App Store)
