Discover Projects with 'Firebase' Expertise

I need an experienced mobile app developer to build PsychChartAI, a cross-platform iOS and Android application designed for PMHNP students and psychiatric providers. Version 1 will be a non-PHI educational and documentation support app featuring user authentication, subscription management, SOAP note templates, an MSE builder, psychiatric ICD-10 references, medication guides, screening tool resources, and PMHNP board preparation content. The app should have a clean, intuitive interface and be built with scalability in mind to support future HIPAA-conscious functionality. I am seeking a long-term development partner who can assist with development, testing, app store deployment, and future enhancements.

Hello.

I have a scoped, private project that looks right in your wheelhouse: an end-of-day stock and ETF scanner that runs an analysis engine I already have over Schwab or Etrade API data and emails me when it finds certain reversal signals. It's informational only — no order execution, just scanning and alerts.

The hard part is done: the signal engine is already written and tested (~220 lines of JavaScript), and I have a full written spec. The work is wiring it to the Schwab feed, running it on a schedule, and sending the alerts. I'm open to calling the engine from Node or porting it to your stack — whichever you'd recommend.

Two quick questions:
1. Roughly what would you charge (fixed price) and how long for this first end-of-day phase?
2. Have you worked with the Schwab API (or a similar brokerage API) before?

Happy to share the spec and the engine so you can quote accurately. Thanks!

I want to launch an on-demand security-guard platform made up of three tightly integrated parts: a customer-facing Android app, a guard-facing Android app, and a web-based admin panel.

Customer app
Users must be able to search for available guards, schedule or book instantly, watch a real-time map as the guard travels to the job, and leave ratings or reviews once the work is done. Smooth in-app payments and push notifications for booking status changes should sit behind these core flows.

Guard app
Guards receive job notifications, choose to accept or decline, see turn-by-turn GPS navigation, and manage an up-to-date work calendar from their phone. Their location feeds the customer’s live-tracking map, so the background GPS service needs to be battery-efficient and reliable.

Admin panel
Through a secure web dashboard I need to create and edit guard profiles, view live bookings, resolve disputes, run payout reports, and configure pricing rules. Role-based access is important so supervisors can be limited to read-only analytics while finance handles payments.

Tech expectations
• Native Android development (Kotlin or Java) with clean architecture
• RESTful or GraphQL API that both apps consume
• Real-time location powered by Firebase, Socket.IO, or a comparable solution
• Secure authentication (JWT, OAuth, or Firebase Auth)
• Scalable database and cloud deployment, preferably AWS, GCP, or Azure

Deliverables
1. Customer Android APK + source code
2. Guard Android APK + source code
3. Web admin panel with source code
4. Documented API and database schema
5. Setup guide plus a short video walkthrough of key user journeys
6. Two-week post-launch support for critical bugs

Acceptance criteria
• A customer can complete a full booking, track the guard in real time, and leave a review with no crashes.
• A guard can accept a job, navigate to the site, mark arrival/completion, and see the shift on the schedule.
• Admin can view that booking, edit guard details, and trigger a payout report.

If you have built marketplace or logistics apps with live tracking before, your experience will be highly valuable. I’m ready to move quickly once we agree on milestones and timeline.

I am starting a multi-phase project to build a scalable voice-chat room application for Android, and I want Phase 1 completed first. The core stack is Flutter for the client, Firebase for auth, real-time audio and data, and a clean, modular architecture that can grow into later features such as Coins, VIP, Gifts, Agency, Family and Rankings.

Mobile OTP login is my top-priority authentication method, though Google sign-in must also work smoothly. Every build needs to be pushed to a private GitHub repository that sits under my own account; I retain full ownership of all source code, server instances and databases.

Phase 1 scope and deliverables
• OTP and Google authentication
• User profile creation & editing
• Create / join voice rooms with room-wide audio
• In-room admin controls: mute / unmute, kick, block, assign admins
• Basic web admin panel for user & room management
• Clear, well-documented Flutter + Firebase code that follows scalable, layered architecture

When you reply, include:
• Relevant voice or real-time audio apps you have shipped in Flutter
• A high-level timeline broken into logical milestones
• A cost breakdown per milestone that fits the current phase budget
• Any questions you need answered before starting

I plan to move straight on to Phase 2 once this milestone is accepted, so clean code, Git hygiene and future-proof structure are critical.

I need a straightforward mobile application that lets teachers upload their course documents and gives students a smooth way to access them on both iOS and Android.

Core flow
• Teacher side: secure log-in, simple dashboard to upload, rename, replace or delete PDF/Word documents and tag them by subject or class.
• Student side: browse or search by tag, read the document inside the app with a built-in viewer, or tap once to download and keep an offline copy.

Accounts can live on Firebase or a similarly easy-to-maintain backend; whatever stack you prefer is fine as long as the upload/download speeds are solid and the UI stays clean. I will provide basic wireframes and branding assets—your role is to build the functional app, connect it to the backend, and deliver tested APK and IPA bundles plus source code in Git.

Acceptance criteria
1. Upload of at least a 20 MB PDF succeeds under normal 4G.
2. Document viewer renders correctly on recent iOS and Android versions.
3. Downloaded files open from the device’s file manager.
4. Simple analytics (e.g., Firebase) records number of views and downloads per document.

If this scope sounds comfortable, let’s get started.

I already run a Wowonder-based social platform and now need the companion Android app tailored to match it. The base Wowonder Android source will stay intact in terms of colour palette, logos, and general UI, because it must reflect the branding users already recognise on the website.

What makes this job more than a straight compile is the set of custom features I want layered on top of the standard feed, messaging, and notification tools. I’ll share the full list after we sign an NDA, but in broad strokes they involve:

• Additional in-app actions tied to our existing back-end endpoints
• Minor tweaks to certain screens so user flows mirror the web version
• Extended push-notification logic with Firebase to support the new actions

All code must remain clean, well-commented, and compatible with the current Wowonder PHP back end. Deliverables are a production-ready APK, the updated Android Studio project, and a short change-log so my in-house devs can follow the modifications.

Once everything compiles without errors and we confirm the custom functions work smoothly on at least two recent Android versions, the project is complete.

This is a Flutterflow app called CARS which stands for Cybersecurity Awareness & Resilience Solution. I am a Phd student at NSU and I will be engaging in developmental research for microbusiness owners testing cyber awareness and resilience for their microbusinesses. This is intentionally a minimal research app. There is no backend all logic is handled in FlutterFlow + Firestore. The app enforces sequential viewing of videos and tracks completion and rewatch behavior only. The focus is on simplicity, reliability, and clean UX. Avoid over-engineering. There are 102 videos that have already been loaded via csv via Rowy into Firebase/Firestore. You already have:
videoId
title
module
order
videoUrl and the videos are set-up to play sequentially one after another. If you get the job, I will provide the csv with placeholders for videourl for privacy. Please review the attached Developer Brief to get an idea of the specifics of this job. Thank you.

We have a near-complete mobile app built in FlutterFlow with a Firebase backend, and we're looking for a strong Flutter developer to finish it and get it submission-ready for iOS and Android.

The app is a private admin assistant for self-employed users in Spain. It connects (read-only) to users' bank accounts via open banking to read invoices and transactions — it never moves money. The codebase and Firebase project are already set up and owned by us; you'll be added with full access from day one.

WHAT'S ALREADY DONE
- Firebase Auth and sign-in
- Core app structure and screens
- A provider-abstraction layer for the bank connection
- An initial sandbox integration against one aggregator (Tink)

WHAT WE NEED YOU TO FINISH
- Build the bank-connection flow end-to-end against Powens (our chosen open-banking aggregator), with secure server-side token handling and continuous background refresh. Note: there is an existing Tink integration, but Tink is NOT the provider going forward — you'll migrate the connection to Powens through the existing abstraction layer.
- Spanish market configuration: bank coverage, locale, EUR, full localization.
- Apply our brand theme (warm cream / burgundy / gold, plus dark mode) from the supplied design system.
- Build the remaining screens and UI polish.
- Account deletion and full user-data deletion (GDPR requirement).
- QA on a clean iOS build and prepare App Store / Google Play submission.

HOW WE WORK
- The GitHub repository and the Firebase project stay under our ownership; you work as a collaborator we add on day one. No work lives only in your account.
- Fixed-price milestones: each is delivered, verified by us (working build + short file-change summary), accepted, then paid the same day.
- Clear written updates. We move fast and need someone transparent and proactive.

Budget: USD 1,000 fixed for the full remaining scope, split across milestones we'll agree up front. Timeline: start now; Spain launch targeted for September 2026.

In your proposal, please answer:
1. Your experience with FlutterFlow plus custom Firebase Cloud Functions — have you worked on an exported FlutterFlow project directly in GitHub?
2. Have you integrated Powens, Tink, or another PSD2 open-banking aggregator (read-only AIS)? Briefly, what did the flow look like?
3. Are you comfortable working in a repository we own, as a collaborator, delivering against fixed milestones (delivered, verified, paid)?
4. Your estimate in days to complete the scope above, and your availability to start this week.

I am expanding the mobile team at Mux Digitals and need a passionate Flutter engineer to work with me in our Multan office on a full-time, onsite basis. The day-to-day focus will be building and maintaining cross-platform applications with Flutter and Dart, writing clean, testable code, and collaborating closely with designers and backend developers to ship new features on a steady cadence.

Your primary strengths should be:
- State management
- API integration
- UI/UX design

Provider is our state-management approach of choice, so solid, real-world experience with it is important. Familiarity with Firebase services as well as the app-store and Google Play submission process will earn extra credit.

The work involves iterating on existing apps and spinning up green-field modules, reviewing pull requests, and ensuring every release meets performance, accessibility, and security standards. Clean architecture, well-named abstractions, and thoughtful commit histories are non-negotiable; they keep our growing codebase maintainable.

If you are ready to create beautiful, reliable mobile apps side-by-side with a collaborative team, send over your résumé and a portfolio link that clearly highlights previous Flutter projects. I look forward to building great products together here in Multan.

I want to create a modern property marketplace that gives Sri Lankans the slick, intuitive feel of Realestate.com.au, PropertyGuru and Domain while being tailored to our own market realities. The most critical audience for launch will be local buyers and Sri Lankans living abroad, so every interaction has to feel fast, trustworthy and easy to use wherever they are in the world.

For local buyers, the platform must open with rock-solid property search and filtering—location radius, budget sliders, bedrooms, new-build status, the works—delivered instantly and ranking results intelligently. I’d like clean map views, saved searches and push notifications baked in from day one.

The project itself breaks down into four concrete deliverables:
• Responsive public website
• Full-featured iOS app
• Matching Android app
• Admin dashboard for listing management, analytics and user roles

I’m open on stack, but modern frameworks such as React / Next.js for the web and React Native or Flutter for mobile make sense. The backend should expose well-documented REST or GraphQL APIs, scale on AWS or GCP, and include a secure media pipeline for high-resolution photos and video tours. Please factor in basic SEO, social-share metadata, Firebase or similar push services, and a staging environment for QA.

You’ll handle UI/UX, development, automated testing, deployment and post-launch support. Clean, commented code in Git, regular sprint demos and clear milestones are essential. When you reply, show me comparable marketplaces you’ve shipped, outline your proposed tech stack, and sketch a realistic timeline from kickoff to App Store / Play Store approval.

Skills: PHP, Website Design, Mobile App Development, Android, React.js, UI / User Interface, Web Development, React Native

I am building a product that relies entirely on the Firebase stack and I need an experienced Firebase developer to wire up the core backend pieces for me.

Authentication & Roles
– Configure Firebase Authentication so new users pass a Captcha check before account creation.
– Introduce role-based access control with at least one custom role: “Moderator”. The structure should allow me to add Admin or basic User roles later without rewriting rules.
– Write Firestore Security Rules that enforce the role logic cleanly.

Realtime Data
I will be storing bookings, chat messages, and user availability in Cloud Firestore. Your job is to design the collections, indexes, and rules so that:
• bookings update in real time for all parties involved
• chat threads stay scoped to the right booking or user pair
• availability calendars can be queried efficiently

Business Logic
Cloud Functions (Node.js) will power all server-side logic. I need background functions for:
• creating calendar events and reminders when a booking is confirmed
• sending notifications on status changes or incoming chat messages
• running periodic cleanup/scheduling tasks (use Cloud Scheduler where needed)

Push Notifications
Use Firebase Cloud Messaging to deliver device and web push notifications triggered from the Cloud Functions above. Tokens should be stored per user and cleaned up automatically when invalid.

Acceptance
I will consider the work complete when:
1. I can run `firebase emulators:start` and see all services working together locally.
2. A fresh project deploys with one command and the production environment behaves exactly like the emulator.
3. Test users with and without the Moderator role demonstrate that security rules block/allow the correct actions.
4. Booking creation fires the expected Cloud Function and a notification lands on the device.

If you have shipped similar role-based Firebase backends before, please tell me how you handled security rules and Captcha. I am ready to start right away.

My bottled-water business needs a seamless digital experience for customers, drivers, and back-office staff, all connected through a single code-base and secure API layer.

Customer app (Android & iOS)
Users must be able to choose bottle sizes, schedule or repeat an order, pay in-app, and watch their delivery move on the map in real time. A clean, two-tap reorder flow is essential because most clients purchase the same package every week.

Admin web portal
From any browser I should see every order the second it is placed, reassign it with drag-and-drop, view customer profiles, suspend or reactivate users, and consult a simple analytics dashboard that shows daily revenue, fulfillment times, and driver performance. CSV export for accounting will make month-end easier.

Driver app (Android)
The moment an order is dispatched, the driver gets a push notification, taps to accept, and the stop list appears in optimized order. Integrated navigation (Google Maps or similar) should launch with one touch, and the driver must update each step—picked up, on the way, delivered—with a photo or signature capture.

Core expectations
• Unified backend/API powering all three fronts
• Firebase or similar for auth, push notifications, and crash reporting
• Source code, build instructions, and staging links provided at each milestone

Job Description
About the Project:
We are building Travlink, a marketplace for booking private city tours with verified local guides across India—think Airbnb Experiences but focused on authentic, personal local discovery.

The core platform is live, functional, and well-architected. Phases 1 & 2 are complete: tourists can browse hosts, book tours, and pay via Razorpay. We now need a skilled Full-Stack Developer to own Phase 3 onward, focusing on rolling out operations dashboards, media optimization, communication workflows, and scaling the platform.

Current Tech Stack:

Frontend: Next.js 16, React 19, TypeScript, Tailwind CSS 4

Backend: Next.js API routes, Prisma ORM, PostgreSQL (Supabase)

Auth: NextAuth v4, Firebase (OTP)

Payments: Razorpay

Email & Hosting: Resend, Vercel

What's Already Built
Authentication: Tourist & host authentication (Email/Password, Google OAuth, and phone OTP).

Discovery: City search functionality with dynamic filters (Language, price, rating).

Profiles: Host profiles featuring media galleries, user reviews, and calendar availability.

Core Flow: End-to-end booking flow tightly integrated with the Razorpay payment gateway.

Onboarding: An 8-step host onboarding wizard including secure ID upload.

Admin Tools: A 90% complete admin panel for host approval, rejection, and verification management.

What You'll Build Next (Phase 3 Scope)
Dashboards & Operations: Build robust, clean dashboard interfaces for Hosts (earnings tracker, upcoming bookings, profile metrics), Tourists (booking history, cancellations, receipts), and Admins (transaction logs, refunds, and commission tracking).

Cancellations & Automated Flows: Implement the core business logic for cancellation policies and automated refund processing.

Media & CDN Optimization: Migrate local image/video assets to AWS S3 and set up CloudFront (or Cloudflare) for production-grade, fast global delivery.

Communication & Alerts: Replace Firebase OTP with a dedicated SMS gateway (MSG91/Twilio) and build transactional SMS notifications for active bookings.

Location Services: Implement geolocation mechanics for a "Guides Near Me" discovery feature.

(Future scope includes: SEO/Structured Data optimization, Sentry/GA4 tracking, real-time in-app chat, Google Maps integration, and a PWA setup).

Who We're Looking For (Required Qualifications)
Next.js & TypeScript Mastery: Strong practical experience handling state, rendering strategies, and data mutations using modern Next.js patterns.

Backend & DB Proficiency: Deep familiarity with Prisma ORM and handling relational databases (PostgreSQL/Supabase).

API & Payment Security: Confident designing clean REST APIs via Next.js API routes and working with custom payment gateway webhooks (Razorpay/Stripe).

Tailwind UI Implementation: Ability to build highly responsive, pixel-perfect user interfaces cleanly without relying heavily on pre-made design systems.

Codebase Adaptation: You should be entirely comfortable stepping into, reading, and iterating on top of a well-structured, production-ready codebase.

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

I’m ready to commission a full-stack mobile application that lets households in my town find, compare, and book local electricians, plumbers, and general handymen— all from one place on both iOS and Android.

Core experience
The app must read a user’s location and instantly surface tradespeople who are not just nearby but actually available in real time. From there, users should be able to pick a time-slot, confirm the job, exchange messages, and pay without leaving the interface. Push notifications and automated reminders need to keep both sides on schedule.

Messaging & reviews
After each job, customers leave a verified review that becomes part of the tradie’s public profile. Those ratings, plus previous chat history, help future users decide quickly and confidently who to hire.

Role-based accounts
Each address can host multiple sub-accounts, so tenants and landlords share one property record while keeping their own logins. Both parties see booking history, invoices, and chat transcripts, which removes the usual back-and-forth and creates a lightweight property-management layer.

Internationalisation
The entire journey— onboarding, search, booking, chat, and notifications— must switch seamlessly between Traditional Chinese, Simplified Chinese, and English.

Payments & tech
Please integrate secure card processing and the usual wallet options. I’m open to your preferred stack, though a cross-platform framework such as Flutter or React Native, paired with a scalable backend (Firebase, AWS, or similar), seems logical.

Deliverables I need from you
• UX/UI designs in all three languages
• Production-ready iOS and Android builds
• Admin dashboard for tradie onboarding and dispute handling
• Tested, documented source code and deployment guide

IP Agreement is required.

If you’ve built location-based marketplaces or booking engines before, I’d love to see them along with a brief outline of the tools you’d choose for this project and why.

Skills: Mobile App Development, iPhone, Android, iPad, UX / User Experience, iOS Development, React Native, Flutter

I need a detail-oriented tester to focus exclusively on the load-time performance of my new mobile game. Your task is to open every screen, level, and menu on both fresh installs and returning sessions, then capture precise timing data so I can see where players might be kept waiting.

Please work with at least two different devices and OS versions (Android and/or iOS), use any standard profiling tools you prefer—Android Studio profiler, iOS Instruments, or even Firebase Performance Monitoring—and record the exact steps that reproduce slowdowns. Screen-recordings or GIFs alongside raw timing logs are essential, as I want to pinpoint what happens before the splash screen, between screens, and during level transitions.

Deliverables I’m expecting:
• A table of measured load times for each device and game section
• Video or screenshot evidence supporting every metric
• A concise report summarising the worst offenders plus practical optimisation suggestions

No functional or usability checks are required; I only need hard performance numbers tied to load times. If you can turn this around quickly and communicate findings clearly, let’s get started.

**Title:** Full-Stack Developer — Aerospace Prime Contractor Operations Platform (React + Supabase)

---

**Overview:**

FabNet UAE is an aerospace engineering design house and manufacturing network based in the UAE. We serve OEM clients in aerospace, defence, and oil and gas — including Tier 1 suppliers and government-linked manufacturers such as ADASI and Edge Group.

We are building a professional client-facing operations platform. This is not a website redesign or a simple order tracker. It is a multi-role B2B platform where OEM clients submit RFQs, track their orders in real time from design to delivery, and access controlled documents securely — with a full immutable audit trail compatible with AS9100 quality standards.

---

**Phase 1 scope — 4 modules:**

Module 1 — Public website. 5 pages. Professional aerospace aesthetic. Original design. Enquiry form with email notification.

Module 2 — RFQ and quoting. OEM client submits RFQ through portal. FabNet admin prepares and issues a multi-currency quote in AED, USD, or EUR. Client accepts within portal. On acceptance — RFQ auto-converts to a live order.

Module 3 — Order management. 14 order stages tracked with an immutable append-only audit log. Digital sign-off on key milestones. Non-conformance capture. 10-year data retention. Full order export as a single PDF package for AS9100 auditors.

Module 4 — Controlled document sharing. Supabase Storage with role-based access. Signed expiring URLs for suppliers. Server-side PDF watermarking before link generation. Full access log. No direct file links to external users.

---

**Tech stack:**

React + Tailwind CSS, Supabase (PostgreSQL + Auth + Storage + Edge Functions), Resend API for email notifications, Vercel hosting, PDF generation via React-PDF or Puppeteer.

Phase 2 will add SharePoint Graph API and Zoho Books integration — the Phase 1 developer gets first right of refusal on Phase 2 and Phase 3.

---

**You must have:**

- Minimum 3 years React and Supabase — not Firebase, not another backend
- Real B2B portal in your portfolio — multi-role, operations or SaaS — not landing pages
- Experience implementing Supabase Row Level Security — describe a project
- Experience with server-side PDF generation in React
- Strong written English — daily updates required
- Willing to sign NDA and IP assignment before work starts
- Milestone-based payment — not 100% upfront

---

**To apply — answer these 4 questions or your proposal will not be reviewed:**

1. Share one B2B portal you have built — what does it do, how many user roles, what backend
2. Describe one project where you implemented Supabase RLS — what tables, what roles
3. Describe one project where you generated a PDF from React — what library, what output
4. Provide your fixed price quote broken down by Module 1, 2, 3, and 4 separately

Full technical brief with complete module specifications attached as a document.

Title: Custom IoT Backend + Flutter Mobile App for Smart Monitoring System
Description:
We're building FloraPulse, a commercial smart plant watering system using ESP32 microcontrollers with soil moisture/temperature sensors across up to 6 pots, plus pump control.
Our ESP32 firmware is being handled in-house and will communicate via MQTT (topics and payload structure will be provided/finalized together). We need the backend and mobile app built to work with this setup.
What we need:
1. Backend Server

Node.js or Python (your choice) + database (PostgreSQL/MongoDB)
MQTT broker integration (self-hosted Mosquitto or managed service — your recommendation)
REST API for mobile app: read sensor data, send control commands, manage devices
User authentication (signup/login, multi-tenant — each customer manages their own device)
Push notification triggers (low water, low moisture, device offline, watering complete)

2. Flutter Mobile App (iOS + Android)

Custom UI matching our provided design (attached) — branded dashboard, sliders for pump speed/watering duration, start watering button, device status, water reservoir level
Sensor monitoring screen — soil moisture & temperature for 6 pots, color-coded status
Push notifications (Firebase Cloud Messaging)
User login/device pairing flow

3. Deployment

Backend deployed to cloud (AWS/DigitalOcean/Render — your recommendation)
App builds prepared for App Store & Play Store submission (we'll provide developer accounts)

Attached: Reference UI design, MQTT topic/payload spec (to be shared)
Requirements:

Backend development (Node.js/Python) + database design + MQTT experience
Flutter development (published apps preferred)
Familiarity with Firebase push notifications

Please share:

Similar projects you've completed (IoT backend + mobile app)
Estimated timeline
Fixed cost quotation
Your recommended tech stack (backend framework, hosting, MQTT broker)

Budget: Open to discussion based on your proposed timeline and stack.

Skills: Mobile App Development, iPhone, Android, Node.js, MQTT, Backend Development, Flutter, Google Firebase

Description:

Experienced Flutter developer needed for a paid 30-minute technical consultation ($25-50) to discuss feasibility and approach for a mobile app startup (patent pending).

I have a working prototype and validated concept. Looking for honest technical input before moving into full development.

Must have:

Published Flutter apps on both App Stores
Firebase and RevenueCat experience
Android kiosk mode experience
Strong API integration background
If the conversation goes well this leads to a full project ($5,000-8,000 budget) starting July 2026.

Answer all screening questions in your proposal or your application will not be reviewed.

• Have you published Flutter apps on both the Google Play Store and Apple App Store? If yes, please share links.
• Have you worked with Android kiosk mode, screen pinning, or device owner mode to lock a device to a single app? Please describe your experience.
• If an app deep links into a third-party app (like a streaming service) to play content — what's your approach to preventing the user from navigating within that app and returning them to your app when done?
• Have you integrated RevenueCat for in-app subscription billing on both iOS and Android?
• Have you used Firebase Firestore and Firebase Authentication together in a production app?
