I already have a working iOS and Android code-base and now need a developer who can take it several steps further. The focus is on rounding out the business database module and layering in richer ways for users and administrators to interact. Core feature work • Business registration: new screens must capture basic information, detailed profile data and any extra, customizable fields I configure from the admin panel. All data should flow seamlessly into the existing DB and respect the current validation logic. • Admin access: extend the back-office so I can search, review, approve or edit every submitted business profile, then trigger status updates to the owner. • Communication options: businesses and customers need one-tap access to phone, text and in-app chat. Live video streaming is required as well, so users can launch or join a real-time demo straight from a listing. • Meetings & reservations: integrate a simple scheduler that lets visitors book a slot with the business and stores it alongside the profile. • Directory lookup: refine the current search to surface businesses by category, location or name and show all the new profile details. Tech expectations The existing stack uses native Swift and Kotlin paired with a Firebase backend. You are free to recommend better libraries for chat and streaming (e.g. WebRTC, Twilio, Agora) as long as everything stays fully functional in both stores. Deliverables 1. Updated Xcode and Android Studio projects with the new screens and services wired in. 2. Source code checked into my private Git repo with clear commit messages. 3. A short README covering setup steps, third-party services used and any new environment variables. 4. Test build links (TestFlight / internal track) that demonstrate registration, comms and booking flows end-to-end. Acceptance criteria - All three registration form types save and retrieve correctly. - Phone, text, chat and live video launch reliably from a listing on both platforms. - An admin user can edit a profile and see changes reflected instantly in the public directory. - Meeting reservations create calendar entries and send confirmation notifications. If you have shipped comparable features before and can move quickly inside an existing code-base, I would love to see your approach and timeline.

Hi, The main risk here is keeping the new business fields, admin edits, and public directory in sync without breaking the current Firebase data model. I’d also treat chat/video as separate dependencies so the app stays stable on both iOS and Android instead of becoming tied to one SDK choice. My first focus would be the business profile flow: registration forms, configurable admin fields, save/retrieve logic, and the approval status path back to the owner. From there I’d wire the listing actions one by one so phone, text, chat, video, and booking all launch from the same business record with clean validation and error handling. Initial work focus: - Review current Swift/Kotlin + Firebase structure - Map business profile and custom field schema - Extend admin edit/approve flow - Add listing actions for comms and booking - Verify sync and notifications end to end One quick question: should video, chat, and booking all be stored under the same business profile document, or do you already have a separate subcollection structure in Firebase?

Hello, I would keep Swift, Kotlin and Firebase, then define the admin-configured business fields as a versioned schema because registration, approval, search and public profiles all depend on the same data contract. For live video, I would pick Twilio or Agora after checking store requirements and current Firebase Auth/user roles. - You get three registration flows mapped to validation and existing Firebase records. - Admin gets search, approve, edit and owner status notifications with rules updated. - Listings get phone, SMS, chat, video join/host and booking actions on both apps. - I add QA cases, README env notes, Git commits and TestFlight/internal builds. Which Firebase database and admin panel are in place now: Firestore, Realtime Database, or a custom back-office? I can start by auditing the repo and confirming the data model. Roman

Hi, Quick question: for the business registration flow, do you want the customizable fields from your admin panel to appear dynamically in the native apps, or should those be baked in during each build release? We've shipped native iOS and Android apps with Firebase backends before, and adding the registration module, admin tools, chat, video streaming, and scheduler is well within reach. The budget and timeline shown are just placeholders — I'll send you a real estimate once we nail down whether those custom fields need live syncing. Regards, Nurul Hasan

The three registration form types will be mapped first against the existing Firebase schema and validation rules, including admin-configured custom fields, so no current data flow is disrupted. I’ll extend the admin area for search, approval, editing and owner status updates, with Firestore listeners keeping directory changes visible immediately. For communications, I’ll wire phone, SMS, chat and reliable two-way live video from each listing, using a focused SDK such as Agora where it fits the current native Swift/Kotlin structure. The scheduler will create reservation records, calendar entries and confirmation notifications. You’ll receive updated Xcode and Android Studio projects, private-repo commits, README/environment notes, plus TestFlight and Android internal-track builds demonstrating the complete flows in 7 days. Should live video be one-to-one demos only, or should a business be able to host multiple viewers? Muhammad Saad

Hi, Are the dynamic registration fields driven by a Firebase Cloud Firestore schema or a custom relational database back-end? Either way, I'll map the custom forms directly to your existing data models while preserving local validation rules in Swift and Kotlin. I handle cross-platform code-bases daily by building clean modular services rather than patching spaghetti code. For the live video streaming and real-time chat, I'll drop in Agora for sub-second WebRTC latency alongside Firestore triggers for push notifications, then wire up the admin directory sync and scheduler. I'll deliver this complete feature set in 1 day for $348, including fully tested TestFlight and internal track builds. Share access to your Git repo and I will dive straight into the code.

Hi! This is a well-scoped mobile project and the feature set you've described maps cleanly onto what I've built before. I'll extend your existing Swift and Kotlin codebase with the full business registration flow including customizable admin-configured fields, build out the back-office approval and profile management screens, wire in one-tap phone, text, in-app chat, and live video streaming using Agora for its reliability and ease of Firebase integration, and add the booking scheduler with confirmation notifications, all committed to your private Git repo with clean messages and a full README. Quick question: for the meeting scheduler, do you need calendar sync with Google Calendar or Apple Calendar, or is an in-app booking record with push notification confirmation sufficient for now? I've shipped native iOS and Android features on top of existing Firebase backends including real-time chat, video streaming, directory search, and admin dashboards, and I know how to move quickly inside an established codebase without breaking what already works. Ready to move fast and keep your existing codebase clean throughout! Hafiz S.

Enhance Cross-Platform Business App The important part here is extending the existing Swift/Kotlin + Firebase architecture without breaking the flows already in production. I can take ownership of the business module and build the new registration/admin workflows, directory search, chat, video, booking and notifications across both iOS and Android. For video/chat, I would first evaluate the existing Firebase setup and then use WebRTC, Twilio or Agora based on reliability and integration effort. One important question: is the current Firebase data model already finalized for the three registration types, or do you need the new customizable fields and admin workflow designed as part of this enhancement? I can work directly from the existing Xcode/Android Studio projects and private Git repository, with TestFlight/internal builds for end-to-end validation. Please ping me to get started and get outstanding results. Thanks!!!
