I’m an experienced Flutter developer with strong cross-platform app development skills for iOS and Android, including TestFlight, API integration, and production-ready app delivery. I can follow structured workflows, communicate clearly in a team environment, and work reliably in US EST hours. Looking forward to your response. Best Regards!

@GeeksEra

Hi Nick, Flutter for iOS + Android with TestFlight testing on a Mac is my daily stack. I've been shipping cross-platform Flutter apps full-time since 2017 (5★ across 72 reviews here). Mac + iPhone are set up and ready for signing and builds. For a fitness app I'd reach for: - Flutter 3.x with Riverpod for state - Firebase or Supabase for auth + sync - fl_chart for workout and progress metrics - Fastlane for clean TestFlight delivery UAE-based, which puts US East Coast mornings squarely in my afternoon, so the hours and weekend availability line up cleanly. I can work for 9 hours for you before i need to rest for the day + I'm available for weekend work. I have all the equipment needed. I have previous experience working in a team and my bid is correct. Quick one — fresh fitness app build, or stepping into an existing Flutter codebase that needs features added and ongoing upkeep? Asif

@Abhishek2117

I’ve been building and maintaining Flutter apps in team setups for years, including fitness-focused products. I understand you need someone reliable who can plug into your workflow, follow processes strictly, and communicate clearly during US East Coast hours. I work with a Mac + iPhone setup for full iOS builds, signing, and TestFlight, so no gaps there. I’m comfortable handling end-to-end Flutter work—clean UI, stable API integration, and keeping builds production-ready. I also prioritize organized task tracking and clear updates so the team never has to chase progress. One thing I’ve seen with fitness apps: consistency in state management and performance early on avoids major refactors later, especially with tracking features. “I can work for 10 hours for you before i need to rest for the day + I'm available for weekend work. I have all the equipment needed. I have previous experience working in a team and my bid is correct.” How is your current team structured (PM, backend, designers)?

@temoberishvili

Hello! I see you're looking to build a cross-platform fitness app using Flutter, which is a great choice for reaching both iOS and Android users. With around 10 years of experience in mobile development and a solid background in Flutter, I can help you create a user-friendly app that stands out. Your goal of delivering a quality fitness app during USA working hours is clear, and I’m comfortable aligning with that schedule. Some similar things I've built: a regional booking platform for a tutoring company, an internal CRM for a property agency, and a React Native field-reporting app. Let’s discuss how we can make your vision a reality. Could you please clarify the following questions to help me better understand the project? Q1: What specific features or functionalities are you envisioning for the fitness app? Q2: Do you have any design preferences or existing branding materials that should be considered? Q3: Are there any particular third-party integrations you plan to include, such as payment gateways or fitness APIs?

Hi Nick, I’ve developed multiple fitness apps with features like workout plans, video libraries, and social sharing, and I’m also a fitness enthusiast myself. I can bring valuable insights to your project beyond just coding. I’m a strong advocate for agile methodologies and believe in delivering small, usable features quickly. This approach allows us to gather real user feedback and refine the product based on actual usage, rather than assumptions. With 15 years of experience, I’ve worked extensively with both front-end and back-end technologies, leading teams and managing projects from start to finish. I’m equally comfortable with server management and CI/CD pipelines, ensuring that I can handle all aspects of development. Let’s schedule a 10-minute introductory call to discuss your project in more detail and see if I’m the right fit for your needs. I’m looking forward to hearing more about your exciting project. Best, Adil

Are there any specific fitness app features or functionalities you're aiming to integrate in your current project?

I'm excited about the opportunity to bring my Flutter expertise to your diverse app development projects. With a strong background in both iOS and Android platforms, I'll ensure seamless end-to-end app delivery.
