Hey there, Wrapping your existing eSIM backend into a polished web and mobile experience requires more than API connection, it needs a reliable user flow across every device. I'll build the React web app and mobile experience around your REST APIs with secure authentication, eSIM activation controls, usage tracking, chat support, and multilingual support for English, Spanish, and French. Keeping translations structured from the start will help prevent layout issues across languages. I've worked on API-driven platforms with dashboards, mobile apps, and customer-facing workflows where clean architecture and handover were important. I'll focus on modular code, performance optimization, testing against your live endpoints, and a clear Git-based delivery process for your team. Do you already have the brand style guide and translation files prepared? Looking forward to collaborating with you.

We wrap existing APIs into polished, branded multi-platform experiences — exactly the scope you've described: take a working backend, expose it through a premium web app and native iOS/Android clients. Our approach for your eSIM platform: • Web portal: React or Vue, responsive, fully branded — plan selection, purchase, activation, account management • iOS app: Swift/React Native, App Store ready — eSIM QR install flow, account dashboard, push notifications • Android app: matching feature parity, Google Play ready • API integration: connect all screens to your documented backend endpoints, handle auth, error states, offline • Branding: your design system applied consistently across all three surfaces • White-label config: theme tokens so you can re-brand per partner without code changes We'd recommend starting with web + Android simultaneously, then iOS — reduces App Store review time from the critical path. Can you share the API docs and your existing design assets or brand guidelines? Happy to scope Phase 1 (web only) vs full three-platform delivery.

Hi, this is a frontend integration problem with real production constraints, not a greenfield backend build, and that usually changes how I structure the delivery. The real engineering risk is keeping account state, activation status, and usage metrics consistent across web and mobile while still hitting accessibility, localization, and release-quality UX targets. I’ve built several production systems where the core engine already existed and the work was to wrap it in a maintainable user-facing layer with clean handoff. The closest examples here are Custom Feature Development & Integration and AI-Driven Marketing Suite Development -- 2, both centered on extending live systems with modular UI, API-connected workflows, and documentation an internal team can actually use. I typically design this by separating API client contracts, state management, and presentation layers so branding and multilingual content do not get tangled with business logic. With a REST backend and stable JSON, that contract boundary matters more than the specific client framework. For this kind of build, I’d pay close attention to activation/deactivation idempotency, usage refresh behavior, error recovery, and localization-safe layout rules across English, Spanish, and French. If useful, I can sketch the client architecture and state model for auth, usage tracking, and activation flows before implementation. Thanks, Hercules

Hi, Your eSIM platform will be transformed into a fully branded web and mobile experience with smooth API integration, multilingual support, and a polished user journey across all devices. • Do you already have the final brand guidelines, including colours, fonts, and design references? • Which features from your existing eSIM API should be prioritized for the first release? • Do you have a preferred technology stack for the mobile applications? The solution will include a responsive website and mobile applications connected securely with your existing REST APIs. The development will focus on clean architecture, reusable components, secure authentication, real-time usage tracking, eSIM management, and customer support features. Previous experience includes building API-driven platforms, mobile applications, and branded SaaS products with strong attention to performance, user experience, and maintainable code. A seamless digital experience that matches your vision will be the priority. Would be happy to discuss your API structure, timeline, and development milestones in chat. Best regards Farhin B

@Zaiyan

I can create a polished, fully-branded experience for your eSIM platform, focusing on a clean user interface across web and mobile. My first step will be to connect the existing REST API endpoints to the new public-facing website, ensuring a smooth integration. Based in Toronto, I work efficiently and prioritize communication, so you can expect quick responses throughout the project.

@melikatfz

hello, The biggest thing is delivering a seamless branded experience across web and mobile while keeping every interaction perfectly aligned with your existing eSIM API, so the frontend should be built around a reusable, API-first architecture from the beginning. Is your REST API already fully authenticated and production-ready, including endpoints for activation, usage tracking, and account management? Should the multilingual content be managed through your backend, or would you prefer a frontend localization system that's easy for your team to maintain? The implementation would focus on creating a consistent design system across the website and mobile apps, integrating your existing APIs, and keeping the codebase modular so future features can be added without restructuring the project. Since the backend is already in place, the priority will be delivering a fast, reliable user experience that reflects your brand while ensuring smooth deployments to the App Store and Google Play. Would you prefer to review the UI/UX direction first, or validate the API integration layer before development begins?

@shayankhan333

eSIM entitlements on iOS are granted by Apple separately from App Store review, so locking that in early is the first milestone, not an afterthought at submission time. I'll build the React web platform and Flutter mobile apps against your documented REST API, covering account auth, eSIM activation/deactivation, real-time usage tracking, and in-app chat. i18n will use a single ARB/JSON string structure so your in-house team can add or update languages without touching component code. One trade-off worth flagging: Flutter gives you near-identical UX across iOS and Android fast, but if Apple's eSIM entitlement approval is still pending, the iOS TestFlight submission sits on hold regardless of how complete the build is. 1. Has Apple already approved your eSIM carrier entitlement, or does that application still need to go in? 2. Best regards, Shayan
