I’m ready to refresh the digital face of my existing business with a brand-new website and a companion mobile app developed in parallel. The goal is a seamless, professional user experience that carries our brand consistently from desktop to phone. The scope covers: • Full design and development of a modern, responsive website. • Parallel build of iOS and Android apps that mirror the site’s core functions. • Integration of back-end services, secure payment or user-account flows where required. • Launch support and hand-off with clean, well-documented code (React, Flutter, or similarly robust stacks are all welcome). When you reply, the one thing I must see is past work that proves you’ve shipped both a website and at least one mobile app for an established company. Live links, store listings, or screenshots are perfect—whatever shows real-world results. If your portfolio lines up, let’s talk through timelines, milestones, and any questions you have so we can get this project moving quickly.

Hello, I understand you want a modern, responsive website and a parallel mobile app for iOS and Android, with brand consistency from desktop to phone, secure user flows, and clean, well-documented code. I will deliver a unified design system and a robust tech stack (React web frontend with responsive UI, and mobile apps in React Native or Flutter to mirror core site functions). I’ll handle back-end integration, secure payments or user accounts where needed, and provide launch support plus a thorough hand-off with clear documentation. I’ll adopt an efficient, milestone-driven process: discovery, design review, parallel build tracks, iterative testing, and smooth deployment, keeping accessibility and performance top of mind. What is your preferred tech stack for the back end (e.g., Node.js with API Gateway, or a serverless approach) and which branding guidelines must be enforced across both web and mobile platforms? Best regards,

I can help with this, I will deliver the responsive website and Flutter-based iOS/Android apps — sharing one codebase across both platforms to keep development fast and consistent with your brand. I will wire up the backend, auth, and payment flows through a single API layer serving all three surfaces. One key advantage: using Flutter Web alongside Flutter mobile means UI components stay identical across platforms, reducing design drift significantly. Questions: 1) Do you have an existing backend or database, or will that be built fresh? 2) What payment provider do you prefer — Stripe, PayPal, or another? Looking forward to potentially working together. Thanks, Kamran
