React Native Social App Build

@irsolutions

With over a decade of experience in React Native development for iOS & Android, backend/API maintenance, and infrastructure deployments, I understand the importance of taking full technical ownership of your existing live mobile app. My background in scaling projects for over 1 million users and handling high-security systems like FinTech positions me well to tackle the challenges of reviewing your current setup, completing the handover, and identifying any technical issues. One strategic insight I can offer is to prioritize creating thorough documentation and ensuring seamless communication during the transition process to guarantee a smooth takeover. In a past project, I successfully migrated a complex app to new infrastructure while maintaining uninterrupted service for users. I am eager to discuss how I can contribute to the long-term success of your app by handling bug fixes, performance improvements, third-party integrations, and new feature development. Let's connect to discuss your project roadmap and how I can support your goals effectively.

Hi - I recently worked with the brand Curapod on that we got the same situation. Client has worked with externally and need to complete handover from there and optimise the codebase for better performance as well as take all the access from the previous team so we take care all about internally and can own this app perfectly. I have prior experience working with such kind of task as well as can manage end to end technical stuffs for your product and trying to get the perfect product onboard. Could we connect to discuss the details and better know each other? I'm ready to start right away! Best, Uttam Shingala

React Native | TypeScript | Node.js | Firebase | iOS & Android | REST APIs Hi, Thanks for sharing the details. You have explained your requirements very clearly. I have experience with React Native, TypeScript, Node.js, Firebase, REST APIs, real-time functionality, third-party integrations and both iOS/Android projects. I’m comfortable working with an existing codebase, even when documentation is incomplete, and understanding the architecture before making changes. For the takeover, I can review the codebase, dependencies, environments, backend, database, deployment process and external services, identify risks or missing access/documentation, and prepare a clear handover plan. If needed, I can also handle migration of the infrastructure to your controlled environment. After that, I can take care of: • React Native iOS/Android development • Backend/API maintenance • Firebase and real-time features • Mapbox/location functionality • OneSignal, Sentry and Adapty integrations • Bug fixing and performance improvements • App Store/Google Play releases • New features from planning through production I’m looking for a long-term technical ownership role rather than just completing isolated tasks. Let’s connect and discuss the current setup and takeover process. Thanks! Purnima

When a project requires a full technical takeover and migration to new infrastructure, the core issue often lies in making sure that the existing functionality remains intact while transitioning to a new setup. I understand that your primary concern may be to avoid any disruption to your live app, data lost, or downtime during this process. Technical review: assess the current codebase and architecture for gaps. Documentation audit: identify and compile any missing documentation and access. Infrastructure migration: transition to a new setup without affecting live operations. Ongoing support: provide long-term React Native and backend development. I am ready to take full ownership of your app and make sure a smooth transition. Could you clarify if there are any specific third-party integrations that needs immediate attention during the migration? Rajavel

Your Firebase setup is likely missing proper security rules and will expose user data if not audited during the handover. I've inherited 4 production apps from external teams — the most common failure points are undocumented API keys, missing environment configs, and broken CI/CD pipelines that weren't transferred. Quick questions - are you currently able to deploy updates independently, or is the previous team still controlling the release pipeline? And do you have admin access to Firebase, App Store Connect, and Google Play Console right now? Here's the takeover strategy: - CODEBASE AUDIT: Full dependency review, identify deprecated packages, document all third-party API integrations (OneSignal, Sentry, Adapty, Mapbox), and map data flows between Firebase and Socket.IO. - INFRASTRUCTURE MIGRATION: Set up new Firebase project under your org, migrate Firestore data with zero downtime, rebuild CI/CD using GitHub Actions or Bitrise, configure staging and production environments. - LONG-TERM OWNERSHIP: Handle React Native feature development, maintain Node.js backend, manage App Store and Google Play releases, optimize performance bottlenecks, integrate new APIs as needed. I've led 3 similar takeovers where the original team left incomplete documentation — one was a fintech app processing 10K daily transactions. Let's schedule a 20-minute technical walkthrough so I can assess the current state before you commit to a migration plan.

@melikatfz

Hi there, Taking over a live production app with an external infrastructure handover is challenging, and without a rigorous architectural audit, hidden technical debt or migration bottlenecks can easily cause downtime and user churn. As a senior full-stack and React Native specialist, I specialize in seamless technical takeovers, complete infrastructure migrations, and long-term ownership of scaling applications without disrupting active users. To ensure a smooth transition, here are my questions: 1. Are all current repository accesses, API keys, and third-party dashboard accounts fully documented and ready for handover? 2. Which cloud provider are you planning to migrate the backend and database infrastructure to? Drop me a message so we can get started right away.

Hi, I’m a senior React Native / TypeScript developer with experience working on production mobile applications and taking ownership of existing codebases. Your project is particularly interesting because this is not simply a feature-development role — you need someone who can take technical ownership of the entire product and become responsible for its stability, releases, infrastructure, and future development. I’m comfortable working independently on imperfect or incomplete documentation and investigating production issues without needing everything to be explained beforehand. For an existing live application, I understand that stability and controlled changes are just as important as writing new code. I’d be happy to start with the technical audit and takeover phase, then continue as the long-term developer responsible for keeping the product healthy and shipping new features. Best regards Raheel

@PINESCRIPTERR

Hi, I understand you need an independent technical assessment of an existing infrastructure-planning SaaS, with particular focus on whether the architecture, document extraction, deterministic decision logic, scheduling engine and test coverage are robust enough to become a world-class product. I can review the existing codebase and architecture after the NDA, then assess each critical layer on its own merits rather than assuming an LLM/RAG approach is appropriate. For document understanding, I’ll examine the extraction pipeline across mixed vector/raster engineering drawings, how structured data is validated and how failures are handled. I’ll separately evaluate the decision engine for determinism, explainability and testability, and the scheduling layer for constraint modelling and edge cases. I’ll also review API/data integrations, generated outputs, multi-tenancy, security, observability, deployment and overall maintainability. The assessment will clearly distinguish what is solid, what is fragile, what is missing and what I would change, followed by a practical roadmap toward production-grade/world-class architecture and testing. I’m comfortable working directly with technical/domain experts and challenging architectural assumptions where necessary. I can work under the requested NDA and keep the review focused on the agreed scope. Best regards, Houssame
