With over 7 years of experience as a Full-Stack Web Developer, I bring to the table an in-depth skillset that encompasses every aspect of your project. Notably, I've completed numerous Swift/SwiftUI and React Native commerce apps which perfectly aligns with your current requirements. Very comfortable with API and backend development, I've also intensively worked with platforms like Supabase and have the know-how to ensure a smooth integration process. Having successfully delivered 130+ projects similar in complexity to yours, I understand the importance of optimized code performance, clean coding practices for easier maintenance, and meeting stringent timelines. Upholding these principles, I guarantee all your acceptance criteria will be met promptly. Additionally, my frequent usage of various payment gateways including stripe makes me especially suited to add that finishing touch to your checkout workflow. Moreover, my knowledge of mobile app development extends beyond just writing code. I'm also experienced with release management on both iOS and Android platforms. In fact, my last few projects ended up on both stores with zero issues at review time - so we can be stress-free when submitting Booka to the App Store. Let's get on a call soon to discuss timelines and ensure a booka'licious world for all!

@kamran2012

Hello, I will finish the Booka iOS app: complete the Supabase auth and catalog queries, wire up the Stripe checkout with cart persistence and stock deduction, integrate Onfonmedia Tanzania for OTP and order alerts, then handle TestFlight builds and the full App Store submission until you see "Ready for Sale." On a similar commerce app, setting up Supabase row level security early caught permission bugs before review, saving a full resubmission cycle. I will do the same here. Questions: 1) Is the codebase Swift/SwiftUI or React Native? 2) Do you have the Onfonmedia sandbox credentials ready, or only production keys so far? Share the repo link and I will review the current state tonight, then send a task breakdown with time estimates. Looking forward to your response. Best regards, Kamran

@KatrinaQ

Hi, I'm a senior developer with 20+ years of experience, Top Rated on Freelancer.com with 1,500+ completed projects and a 5-star record, and I've shipped multiple iOS commerce apps end-to-end. I'll review the existing SwiftUI codebase and Supabase setup first, then complete the authentication flow, finish the product catalog queries with pagination, and implement secure user sign-up and login with email/OTP and social methods. After that, I'll wire up the Stripe payment API for checkout, integrate Onfonmedia's SMS gateway for OTPs and order alerts, and harden the app with tests and crash analytics before submitting to TestFlight and handling App Store review blockers. I'll ensure cart persistence, stock deduction, and real-time updates work reliably, and provide production Supabase config with proper error handling across all integrations. I can start immediately.

@corpmember29

Hello, I carefully reviewed the current status of Booka and the remaining scope before App Store launch. Since the UI screens, Supabase project, and basic checkout flow already exist, this is primarily a completion, integration, testing, and release-hardening project rather than a full rebuild. I have 10+ years of experience in iOS/Android development, React Native, Supabase, Stripe integration, SMS gateway integration, secure backend workflows, TestFlight/App Store releases, and eCommerce applications. To answer your questions directly: Yes — I have developed and launched Android and iOS apps on Google Play and Apple App Store. Yes — I have worked extensively with Supabase (Auth, RLS, Realtime, Storage, Edge Functions, and PostgreSQL). Yes — I have integrated Stripe and other payment APIs with secure server-side handling. Yes — I have integrated SMS gateway APIs, including OTP and transactional notification workflows. Yes — I can support publishing on both Google Play Store and Apple App Store. Yes — I can provide one month of post-launch bug fixing and technical support. The implementation will include secure Supabase authentication, real-time catalog queries with pagination, cart persistence, order creation, stock deduction, Stripe checkout, Onfonmedia SMS for OTP and order confirmations, crash analytics, App Store compliance fixes, production environment setup, and end-to-end release support until the app reaches “Ready for Sale.” Thanks, Christina

@codefusion53

Hi I understand you need hands-on help to finish the iOS version of your “Booka” e-commerce app so it can be submitted and approved on the App Store. The core items are completing the incomplete auth/catalog/checkout logic with Supabase, wiring payments and Onfonmedia SMS for OTP and order status, and then polishing, testing, and guiding the full release flow end-to-end. I’m Justin, an AI and Web developer who also builds and hardens mobile-facing features, with a strong focus on secure API integration and turning “nearly works” code into reliable production flows. I’ll work inside your existing Swift/SwiftUI build patterns and your current Supabase setup, emphasizing correctness, secure handling of keys/tokens, and clear next steps that map to App Store launch requirements. I’d tackle this in phases: first, close Supabase gaps by completing authentication flows (email/OTP and any scaffolded social sign-in) and finishing real-time catalog queries with proper server-side pagination. Second, complete checkout by implementing cart persistence, order creation, stock deduction, and connecting your payment API to the existing backend so orders trigger SMS updates. Third, integrate Onfonmedia for OTP and order status with robust error handling and retry paths. Finally, harden with tests/crash analytics, produce TestFlight builds, and support App Store Connect validation and “Ready for Sale” submission using your provided repo, keys, and credentials. Best, Justin
