Hi, I am Elias from Miami. I’ve reviewed your needs. This is a takeover + stabilization engagement first, then a steady cadence of features across maps, payments, analytics, and release management for iOS/Android. My approach would be: quick codebase familiarization, dependency and Firebase rules review, CI/CD and release pipeline validation, and crash/analytics instrumentation (Crashlytics + performance) so we can ship safely and measure impact. From there, each feature can be implemented behind flags and released incrementally to avoid regressions. I have a few points I’d like to clarify: Q1: What’s your current stack exactly (Flutter version, Firebase services in use, state management, existing backend beyond Firebase)? Q2: For payments, are you already using Stripe in any form, and do you need ACH via Stripe (Financial Connections / ACH) or a separate provider? Q3: For “Events Near Me” and calendar sync, are events sourced from your own database, third-party providers, or user-submitted content? If you can share repo access (or a read-only link), current build status, and your top 3 launch blockers, I can outline a clean takeover plan and ongoing maintenance cadence.

Hi there, It sounds like you’re at a pivot point where the "v1.0" needs to become a stable, revenue-generating product. Transitioning a codebase in its final stages requires a surgical approach: stabilizing the foundation first so that new features like Stripe flows and Map integrations don't introduce technical debt. Why My Team is the Right Fit We specialize in the Flutter + Firebase ecosystem and have extensive experience managing the "Post-Launch" lifecycle. We don't just push code; we manage the ecosystem (App Store Connect, Play Console, and Domain health). How We Will Address Your Requirements: The Transition (Weeks 1-2): We perform a deep-dive audit of your GitHub repo, documenting the current state and resolving any immediate "cleanup" items before building. Feature Rollout: * Maps & Events: Implementing optimized Geofire queries for "Near Me" searches to keep Firebase costs low. Fintech & Payments: Seamless integration of Stripe/ACH using server-side validation for secure transactions. Data Processing: Building a robust parser to convert PDF invoice data into accounting-ready CSVs. Maintenance & Health: Daily monitoring of Crashlytics, incremental CI/CD releases, and proactive domain/SSL management. Let’s discuss your project requirements in detail. I’m ready to get started immediately. Looking forward to working with you. Best Regards, Sunil

@DeveloperStation

Hi there, We’ve developed several apps with similar features, including event discovery, ad monetization, and payment integrations. We also have extensive experience with Firebase, GitHub, and CI/CD pipelines, ensuring your app remains secure and up-to-date. As a team of dedicated Flutter developers, we can handle both iOS and Android builds, optimizing for each platform’s unique requirements. We also provide backend expertise in Node.js and PHP, so you won’t need to hire separate developers for server-side work. Let’s schedule a 10-minute introductory call to discuss your project in more detail and see if I’m the right fit for your needs. I’m eager to learn more about your exciting project. Best, Adil

Hi, Are you looking for a team that can seamlessly take over your app’s codebase and enhance it with new features? I’m excited to help you maintain and improve your iOS and Android app after launch. With extensive experience in Flutter, Firebase, and Stripe SDKs, I can ensure your app stays healthy while pushing out new functionality like event map searches and CSV invoice generation. I prioritize clear communication and milestone reporting, and I understand the importance of regular Play Store and App Store releases alongside effective crash analytics. Let’s discuss how I can support your app’s growth and maintenance. Best Regards, badar madni

Hello! As per your project post, you’re looking for a professional team to take over your near launch iOS and Android app, stabilize the existing codebase, and progressively introduce new functionality such as location based event discovery, monetization, financial reporting, and payment integrations. The goal is to ensure long term app health, structured feature rollouts, and reliable store updates with clear communication and milestone reporting. My focus will be on delivering structured codebase familiarization and cleanup, followed by phased enhancements including map based “Events Near Me” search using modern map APIs, AdMob integration for free tier monetization, automated PDF to clean CSV conversion compatible with QuickBooks, in app ROI and category reporting dashboards, secure Stripe and ACH payment flows, and external event sync into the in app calendar. The system will leverage Flutter, Firebase services, crash analytics, and structured release cycles for App Store and Play Store updates. I specialize in maintaining and scaling Flutter applications with Stripe SDK integrations, Firebase backend workflows, analytics monitoring, and continuous deployment pipelines via GitHub. My approach ensures clean architecture, measurable milestones, transparent reporting, and incremental production ready releases. Let’s connect to define the takeover plan and feature rollout roadmap so we can ensure a smooth transition and sustainable growth. Best regards, Nikita Gupta.

I understand you’re wrapping up app development and need reliable support to keep things running smoothly while adding new features. From my experience taking over similar apps just before launch, I focus first on cleaning up the codebase and fixing any emerging bugs to ensure stability. For your new features, integrating AdMob for free users and syncing external events into the calendar are common tasks I’ve handled, often starting with clear API testing and user-targeted rollout plans. Converting PDFs to CSV for QuickBooks can be tricky with varied formats—do you have a standard template for invoices, or do they differ? That will guide the best parsing approach. Regarding payment flows, combining Stripe and ACH usually means ensuring PCI compliance and smooth user experience. Have you set up your backend to handle webhooks, or do you need support there? Also, for ROI and spending reports inside the app, I recommend designing data collection with Firebase analytics to fill those insights consistently. I’m ready to dive in, review your current app status, and set up a clear milestone plan for delivering these features without disruption to your users. Let’s get your launch and maintenance on track fast.

Hi, I can seamlessly take over your Flutter codebase, stabilize and optimize it, then roll out features like map-based event search, AdMob integration, Stripe/ACH flows, CSV exports for accounting, analytics, and structured store releases—with clear milestones and proactive maintenance throughout. Lets discuss on chat. Regards Abhishek

@techsty2014

Hi there, I will take over your Flutter codebase, stabilize it post-launch, and incrementally roll out the six planned features - map-based event discovery, AdMob for free users, PDF-to-CSV invoice exports, in-app ROI reporting, Stripe and ACH payment flows, and external calendar syncing. Each feature will follow a structured release cycle with milestone reporting, crash analytics via Firebase Crashlytics, and staged App Store and Play Store submissions. For the PDF-to-CSV conversion, I will build the parsing logic inside a Firebase Cloud Function so it runs consistently across both platforms and maps your invoice fields directly to QuickBooks-compatible column headers without manual cleanup on the client side. On the payments side, I will implement Stripe with proper webhook handling and ACH as a secondary method, with full sandbox testing before any live release. Questions: 1) Is the current codebase using a state management approach like Riverpod or Bloc, or will that be part of the initial cleanup? 2) For the event map search, will events come from your own database, a third-party API, or both? 3) Do you have an existing Stripe account set up, or will that need to be configured from scratch? Looking forward to discussing further. Best regards, Faizan
