Hi, I’ve reviewed the project details and the specified tech stack. I estimate that the development can be completed in approximately 12-16 weeks, depending on the finalization of the UI/UX designs and any specific functionalities you need to clarify. A couple of points to discuss: can you provide any existing branding guidelines or preferred design aesthetics for the UI/UX? Also, do you have a specific launch date in mind that we need to target? To ensure a smooth development process, I’d focus on an agile approach, allowing for regular feedback and adjustments. With my experience in mobile applications using Flutter and backend systems with ASP.NET Core, I can manage both the API and the mobile app effectively. Let’s discuss the specifics further to finalize the scope and timeline. Best regards, Mohammad

Good day, thanks for sharing a detailed document, I have reviewed it. Based on your requirements, I understand that you’re looking to build planB as a scalable entertainment marketplace, starting with farms and chalets in Jordan, where customers can discover and book listings while providers manage availability, pricing, and bookings, with Arabic/English support, direct payments, sponsored listings, and future category expansion built into the architecture. Here are some questions, can you please clarify? For Phase 1 direct payment, should the customer see the provider's payment/contact instructions immediately after booking confirmation, or should the provider first manually confirm the booking? For sponsored listings, do you want providers to request campaigns while Admin approves them, or should Admin create/manage all campaigns initially? For the first release, should Customer Web have the same booking functionality as the Flutter apps, or primarily focus on discovery/SEO with booking handled through the app? I would love to schedule a meeting or have a detailed conversation about the project to clarify some concerns about the project, this way I can demonstrate my capabilities perfectly and suggest the best result possible. Regards, Royal Designs Budget and Duration are TBD>

==== Hi - Truong here ==== "FLUTTER ENTERTAINMENT BOOKING APP" - you need a complete product build with mobile apps, admin tools, APIs, and a scalable backend that can grow after launch. I’d structure this in phases: first confirm flows from the requirements, then build Flutter apps, backend services, admin portal, booking logic, notifications, and testing environments. I’d keep the architecture modular with PostgreSQL for data, Redis for fast availability checks, REST APIs, and CI/CD through GitHub so future updates stay manageable. Which features are the highest priority for the first release: customer booking, vendor management, or admin operations? Looking forward to work with you.

Hello, Major risk is unclear non-functional requirements for concurrent users and media streaming throughput which determine architecture choices for scaling, CDN, Redis sizing, and cost estimates. I have delivered multi-platform mobile apps, admin portals, and backend services integrating Flutter/Dart frontends with ASP.NET Core backends, PostgreSQL, Redis, Firebase auth/notifications, and AWS S3. Relevant work includes production chat and media apps with API documentation and CI/CD pipelines; I can map those patterns to planB requirements. I confirm ability to deliver using Flutter/Dart, ASP.NET Core, TypeScript, PostgreSQL, Redis, REST APIs, Swagger/OpenAPI, Firebase, AWS S3/Azure Blob, Azure/AWS, and GitHub/Azure DevOps. My first technical step is to run a 1-week requirements audit to convert the attached documents into an actionable backlog and a scaled architecture diagram. I will propose concrete scaling targets, storage and CDN strategy, and integration points for Firebase and cloud storage during that audit. I note a few clarifications needed: expected peak concurrent users, average/maximum media file size and bitrate, required retention and GDPR/CCPA constraints, third-party licencing or payment gateways, and preferred cloud provider for hosting. These will affect cost, milestones, and timeline. - Do you have target peak concurrent users and average media file characteristics? - Which cloud provider do you prefer for production (Azure or AWS) and any corporate procurement constraints? Happy to hop on a brief call whenever it suits you. @melopgabriel

Hi, Thanks for posting "Entertainment app -- 2" — it lands right in our wheelhouse, and we'd be thrilled to bring it to life. I love turning a solid brief like yours into a polished result you’ll be proud to put your name on. From your brief I can see this involves android, ios, flutter — all areas we handle in-house. We specialise in Mobile App Development, Dart, PostgreSQL, Redis, which lines up directly with what you need. How we'd approach it: - Finalise the screens, user flows and feature list with you - Build smooth, native-feeling UI with clean, maintainable code - QA on real devices, then prepare and ship to the store(s) - Post-launch support and iteration once you’re live I also noted you don’t need clearly stating them in the proposal — that’s clear, and I’ll keep the work clean and strictly on-brief. You can count on tight communication, on-time delivery, and a result that’s effortless to sign off on. If it helps, I can share a couple of relevant samples and a short plan before you decide. Looking forward to it! Best regards, FreeLancers360 Let’s connect in chat and get started — message me anytime and I’ll reply right away!

Hi, there. I understand planB is a full product platform rather than a simple entertainment app, covering Flutter mobile apps for customers and providers, an admin portal, booking and availability logic, sponsored advertising, REST APIs, PostgreSQL, Redis, notifications, cloud infrastructure, testing, UAT and both store releases. The key is building the architecture around reliable bookings, scalable availability and clear ownership of every environment and deliverable. Rather than relying on words, I can build a working demo to demonstrate the approach, functionality, and quality firsthand shortly. My relevant work includes SaaS platforms, eCommerce systems, API integrations and backend-heavy applications where mobile/web interfaces depend on structured business rules and reliable data flows. I can also work with Git-based development, staging environments, API documentation, database design, deployment and complete project handover rather than treating delivery as only the application code. The demo can focus on the core booking flow, provider/customer roles, availability handling and admin workflow, giving you something concrete to validate before the full development plan and commercial breakdown are finalized from the requirement documents. Would you like me to build a working demo for you? I hope we discuss more about the project in chat. Thanks, Fernando Garcia

The important part in planB is not just building screens in Flutter; it’s defining a stable architecture for bookings, provider management, sponsored placements, admin permissions, and release workflows so the product can scale without constant redevelopment. My approach would be to review the requirement documents module by module, identify ambiguities early, and convert them into a phase-based plan with deliverables, milestones, testing, deployment, and support structure. I’ve worked on custom application scopes that combine mobile apps, REST APIs, admin dashboards, databases, and cloud environments, so the proposal would be written from an implementation angle rather than a generic estimate. Your preferred stack is sensible, and I can align the proposal around it while also flagging any area where a different component may reduce long-term maintenance effort. A few things would help before I lock the scope: - Is multi-vendor onboarding and approval part of the first release or a later phase? - Do you need App Store / Play Store publishing included end to end, or release-ready builds plus support? - Is there any target launch window already fixed on your side?

Flutter with PostgreSQL and Redis for planB makes sense if you need real time state without hammering the database, especially once usage picks up. I can set up the CI/CD pipeline on GitHub early so every build ships clean from day one. Available now, can start today, first working build within 5 days. These numbers are based on the post as written, we will refine them after a quick scope conversation. Want me to send a quick plan?
