Responsive Web & Mobile App Build

I’m ready to level up my business with a brand-new, fully responsive website and a cross-platform mobile app that feel perfectly connected. The existing site is completely custom-built, so you’ll be starting on a clean slate—free to propose the stack that best supports long-term growth (React Native, Flutter, Node.js, Django, or anything you trust).

Here’s what the project needs to deliver:

• A modern, device-agnostic website that loads fast, ranks well, and is effortless to navigate.
• Companion iOS and Android apps built from a single codebase, matching the web experience feature for feature.
• A secure backend that handles user authentication, a robust payment gateway, and real-time push notifications through a clean API layer.
• UI that honours my existing logo and colour scheme while keeping the overall look crisp and uncluttered.
• Deployment to production (web) and successful submission to both app stores, with source code handed over in a Git repository plus concise documentation.

Acceptance criteria
1. Key pages load in under 2.5 s on 4 G according to Lighthouse.
2. Sign-up, checkout, and notification flows work flawlessly on the two latest OS versions.
3. Brand colours and logo match the supplied guidelines pixel-perfectly.

When you reply, please include:
• The tech stack you’d use and why.
• An estimated timeline with major milestones.
• Links to at least two live web + app projects you’ve launched.

I value clear communication and proactive problem solving, and I’m keen to get started as soon as we agree on the roadmap. Let’s build something great together.
