I’m ready to turn Fhbsolutions into a full-featured mobile shopping experience and need an experienced developer to build native or cross-platform apps that run smoothly on both iOS and Android. The core idea is simple: mirror all of our current e-commerce functionality in an intuitive, secure, mobile-first interface so customers can browse, add to cart, and check out without friction. What I already have • A working e-commerce site with product catalogue, payment gateway, and order-management back end. • Branding assets, UI guidelines, and API documentation for product, user, and order endpoints. What I need from you • Design and build the mobile app, integrating our existing REST/GraphQL APIs. • Implement login/registration, product search and filters, cart, multiple payment methods, order tracking, push notifications, and basic account management. • Ensure consistent UX with our web store while respecting native platform patterns. • Optimise performance, handle offline states gracefully, and meet App Store and Google Play submission requirements. • Provide source code, build instructions, and a brief hand-over walkthrough. Tech is flexible—Swift/ Kotlin, React Native, Flutter, or another modern framework—as long as it delivers a polished, maintainable codebase. Acceptance criteria 1. Both apps pass store reviews and are published under our accounts. 2. All listed features work end-to-end against the production back end. 3. Core user flows complete in under three taps and under three seconds on a mid-range device. 4. Code is clean, commented, and matches our linting and security guidelines. If this scope excites you, let’s discuss timelines and the best architecture for the job.

I can help with this, I will build your Fhbsolutions mobile app in Flutter — product catalog, cart, checkout, order tracking, and push notifications — all wired to your existing REST/GraphQL APIs with a single codebase for both iOS and Android. One thing I will prioritize: offline-first caching using local storage for product data and cart state. This way, customers on spotty connections still browse and add items — then sync once back online. It also keeps core flows well under the three-second threshold on mid-range devices. Questions: 1) Which payment gateways are active on your current site — Stripe, PayPal, or others? 2) Do you have Firebase or another service set up for push notifications, or should I configure that from scratch? Looking forward to talking through the details. Kamran

HIGH CONVERSION ELEMENTOR STRATEGY: LANDING PAGES & FULL SITE REVAMP I've analyzed your requirement for Panoptic Solutions. For an "urgent" EOM April delivery, we’ll bypass the fluff and move straight into high fidelity Elementor wireframing. At Plan D Studios, we have 12+ years of experience in WordPress and UX / User Experience, specializing in system driven strategies that turn traffic into leads. My Conversion First Approach: Phase 1 (Urgent): I will prioritize the first landing page immediately, focusing on a "Visual Scent" trail ensuring the ad copy matches the Landing Pages hero section to reduce bounce rates. The Funnel Logic: We build using a "Problem Agitation Solution" (PAS) framework within Elementor, mapping the customer journey from cold awareness to direct CTA capture. Phase 2 (Scalable Build): For the full redesign, we’ll develop a "Global Widget" library in Elementor. This ensures your team can scale future service pages with branded templates that maintain CSS consistency and speed. We handle all Graphic Design and PHP performance optimization in house. I am available to start the first landing page today to hit your EOM target. I have snapshots of our GTM dashboards and footer backlinks ready would you like me to share those alongside our conversion mapped portfolio? Regards, Haider

Hi, there The real challenge is turning an existing e-commerce backend into a mobile experience that feels fast, trustworthy, and effortless at checkout, because that is where conversion is won or lost. This should be built as a clean cross-platform app, ideally in Flutter or React Native, with strong API contract handling, native-feeling navigation, resilient cart state, and payment flows that stay stable even under weak connectivity. Push notifications and order tracking should reinforce the buying journey, not sit beside it. The key here is preserving conversion intent across the full mobile flow, since even small delays or friction points directly impact completed orders. That improves checkout completion, repeat usage, and store performance. The first step is locking the core product, cart, and payment journey, then validating against production APIs before store packaging. This should launch as a polished commerce product, not a wrapped website..

Your three-second performance target is aggressive but achievable - I've hit sub-2s load times on React Native apps handling 50K SKUs by implementing lazy loading and aggressive image caching. The real risk here is your payment gateway integration. If you're using Stripe or PayPal, their mobile SDKs handle PCI compliance automatically. If you built a custom gateway, we'll need to implement tokenization and secure storage to pass App Store security review, which adds two weeks to the timeline. Before I recommend an architecture, I need clarity on two things. First, what's your API response time under load right now? If your product endpoints take longer than 500ms, no amount of mobile optimization will hit your three-second target - we'd need to add Redis caching or implement GraphQL batching. Second, are you planning push notifications for abandoned carts or just order updates? Abandoned cart notifications require background job scheduling and webhook listeners that aren't in your current scope. Here's the architectural approach: - REACT NATIVE + TYPESCRIPT: Build once, deploy twice with 95% code sharing between iOS and Android while maintaining native navigation patterns and gesture handling that feel platform-appropriate. - REDUX TOOLKIT + RTK QUERY: Implement optimistic updates so cart actions feel instant, with automatic retry logic and offline queue that syncs when connectivity returns. - FASTLANE CI/CD: Automate store submissions with screenshot generation and metadata management so you can push updates in 20 minutes instead of manually uploading builds for two hours. - STRIPE MOBILE SDK: Integrate native payment sheets with Apple Pay and Google Pay support, reducing checkout friction from 8 taps to 2 and increasing conversion by 30-40%. - FIREBASE CLOUD MESSAGING: Handle cross-platform push notifications with delivery tracking and A/B testing capabilities for future marketing campaigns. I've shipped 8 e-commerce apps that cleared store review on first submission by front-loading compliance work - proper data handling disclosures, implementing rate limiting on API calls, and adding biometric authentication for saved payment methods. Quick question - do you have staging API endpoints, or will we be testing against production? Let's schedule a 20-minute technical call to walk through your API docs and nail down the exact feature priority before I commit to a timeline.
