As a seasoned Full-Stack Mobile App Developer with focused expertise in React Native, I can confidently expand your current email-based authentication flow by implementing phone-number sign-up/log-in using secure SMS OTP via Firebase Authentication. I have successfully completed similar projects before, integrating Firebase and comparable auth flows into React Native applications. Additionally, I'm experienced in React Native projects that work across both iOS and Android platforms. Therefore, I can guarantee a clean, well-commented codebase that follows existing project conventions while incorporating the necessary changes. Investing over 5 years in the software development industry, I have continuously emphasized user-friendliness and high performance as my project hallmarks—two qualities fundamental to your app's success. As such, launching a production-ready iOS build won't be an issue. With my understanding of Xcode configuration and proficiency in resolving platform-specific quirks, the app will work seamlessly across the latest devices and maintain compatibility for older versions. You can rest easy knowing that I prioritize clarity in communication, adhere to strict deadlines, and offer comprehensive end-to-end support—traits that are crucial for a smooth handover post-launch. My keen attention to detail combined with maintaining an efficient turnaround is something that your project deserves. Let's discuss further to turn your vision for SpakSpak into reality!

I’ve reviewed your requirement and this is my understanding: you have a live React Native app, “SpakSpak,” and you need two structured enhancements. I have 8+ years of experience working with React Native apps in production, including Firebase Authentication (email/password, phone OTP, multi-provider flows), secure user linking, and cross-platform builds. I’ve handled multiple iOS production deployments, including certificate management, provisioning profiles, TestFlight releases, and successful App Store approvals. I’m available to start immediately. Please share access to the current repo and confirm your backend user schema so I can review integration points and begin right away. Best Regards, Deepak

As someone who has honed their craft in the realm of web development, I understand the tremendous importance of clean, secure, and efficient code. In my portfolio, you will find several projects that highlight my expertise in React Native—particularly in tandem with Firebase Authentication. These projects mirror the task before us: integrating phone-number sign-up/log-in with an emphasis on the seamless fusion of existing and new code. One project that comes to mind is a custom React Native app I built for a client which relied heavily on Firebase Authentication for both email and phone number sign-ups/log-ins. I applied precise checks, kept the original code base intact while introducing necessary changes, and ensured clarity and comprehensive documentation for the final hand-off. One strong point I would like to make is my commitment to long-term success. I appreciate your requirement for robust iOS build ready for submission without any surprises. As an experienced developer fluent in Xcode with a solid comprehension of Apple's policies, I can mitigate platform quirks efficiently and guarantee that your app is optimized for both advanced and old supported devices. With me on board, you can be assured that it's not just about development, but also about successful deployment and review clearance

I’ve carefully reviewed your project requirements for extending SpakSpak with Firebase phone-number authentication and preparing a production-ready iOS build. The two-step structure you outlined is clear, and I fully understand the need to integrate OTP login without disrupting the existing email authentication flow, while also ensuring a smooth App Store submission process. I’m a React Native developer with strong experience in authentication systems and production deployments. I particularly enjoy working on clean, scalable implementations that integrate seamlessly into existing architectures rather than patching features on top. Your requirement to keep the original email path fully operational while introducing phone OTP aligns well with how I approach system extensions—structured, minimal, and maintainable. Why I’m a Strong Fit for This Project 1. Firebase Authentication Experience I have implemented: Phone number OTP authentication via Firebase Email/password auth with verification logic Multi-provider login flows (email + phone + social) Firestore-backed user synchronization I understand the importance of: Linking phone credentials properly to existing user records Preventing duplicate account creation Handling OTP retries, rate limits, and verification states securely

Hello, I can extend your live React Native app SpakSpak in two clear phases. Phase 1 — Phone OTP Authentication I will add secure phone number sign-up/login using Firebase SMS OTP, fully integrated with your existing user table and verification flow. The current email login will remain unchanged. The code will be clean, well-commented and follow your project structure. Phase 2 — Production-Ready iOS Build I will configure Xcode, certificates, and provisioning using your Apple Developer account, fix platform issues and deliver a stable iOS build optimized for both new and older devices. I will also guide you through App Store Connect submission to ensure smooth approval. Deliverables - Android build with Firebase phone OTP - Production-ready iOS build (Debug + Release) - TestFlight-ready package & submission guidance - Setup documentation & environment files - Clean source code in version control Experience I have implemented Firebase authentication (OTP, social login, verification flows) in multiple React Native apps and delivered production builds for both Android and iOS. Timeline - Phone OTP integration: 1 days - iOS build & submission prep: 2 days Fixed Price:(can finalize after repo review) I guarantee secure handling of credentials and confirm that no access will be retained after handoff. Please share repo access and any backend endpoint details to begin. Thank you.

Recently helped a client integrate phone-number sign-up with SMS OTP using Firebase Authentication into their React Native app, improving user onboarding speed by 30%. I bring 5+ years of hands-on experience and a track record of delivering high-quality, practical solutions. I keep projects organized, communicate clearly, and ensure deadlines are met. My goal is simple: efficient execution and a result you’re proud of. I can start right away. While I am new to Freelancer, I have tons of experience and have done other projects off site. I would love to chat more about your project! Regards, Cristiano Ferreira
