I’m building an integrated fitness ecosystem that works seamlessly on iOS, Android, and any modern browser. The mobile experience will be written in Flutter, the web front-end in React, with a Node-powered API, Postgres for data, and everything deployed on AWS. Core scope • Exercise tracking – users must be able to log workouts, view progress analytics, and sync their data instantly across devices. • User-specific nutrition plans – the system should calculate macros, generate meal suggestions, and allow plan adjustments in real time. I will provide wireframes, brand assets, and high-level user stories; you’ll handle detailed architecture, coding, testing, and AWS deployment. A clean REST (or GraphQL) interface, secure authentication, and an admin dashboard for content and user management are expected. Key deliverables 1. Flutter mobile app (Android & iOS) fully connected to the backend 2. React web app with identical core functionality 3. Node backend with documented endpoints and Postgres schema 4. Infrastructure-as-code for AWS plus CI/CD setup 5. Brief technical documentation and handover session Acceptance criteria will be feature demonstrations on a staging URL/TestFlight build, code review via Git, and successful deployment to my AWS account. If you’ve shipped comparable cross-platform fitness or health solutions before, let’s talk timeline and milestones so we can get this into users’ hands quickly.

Having spent 5 years in the world of mobile app and web development, I can bring value to your project in a unique way. With expertise in Flutter and React Native, I've mastered the art of writing code across platforms that look and feel native on iOS, Android, and browsers. Additionally, my proficiency in Figma will ensure I work with your wireframes and brand assets diligently, yielding designs that resonate well with your target users. Moreover, my full-stack skill set makes me an ideal choice for this comprehensive project - from handling React for the web front-end to NodeJS for the backend infrastructure and setting up AWS for development. As data security and user authentication are crucial for such a platform, you can rely on me to design Restful or GraphQL interfaces that prioritize safety without neglecting usability. Lastly, my commitment to clear communication ensures you stay updated throughout this process. As we review codes via Git, demonstrate each feature through URLs/TestFlight builds, and finally deploy everything successfully on your AWS account - every step will be synchronized with you. I believe our collaboration could create something special, helping fitness enthusiasts track their progress while also managing their nutrition plans. Thank you for considering my candidacy and I hope we can discuss further about timeline and milestones towards getting this incredible platform into the hands of users as quickly as possible!

As an extensive Flutter developer with 8+ years of experience, I can confidently say that I'm more than capable of completing this project to your utmost satisfaction. My fluency in both Flutter and Android app development will allow me to create an effective, smooth, and attractive mobile experience for your fitness platform. Past projects with notable companies providing API integrations, such as Google, Facebook, Paypal, Stripe and several others, have sharpened my skills when it comes to connecting necessary third-party software promptly and practically. My expertise doesn't end at just the front-end though. Familiarity with React would additionally aid me in crafting the web application for your platform. Not only that but having hands-on knowledge in different back-end technologies like Node.js, Laravel, PHP and CI will ensure a seamless coordination between the Node-powered API backend to the React web app. Most importantly, I value constant communication and collaboration throughout the duration of a project. Daily interactions along with document sharing makes sure we are on the same page every step of the way. This transparency coupled with my penchant for quality workmanship has led to my prior success delivering more than 150 sizeable projects during my tenure in a company role and many more as an individual freelancer
