Good afternoon! I am engaged in cross-platform mobile development on Flutter, working on iOS and Android. I have commercial experience in companies as a Flutter developer. I have a Mac for development, as well as real devices and emulators for iOS and Android for testing and debugging.

In addition to the mobile part, I implement the backend on Python and Django web admin for administrator management.

Hello! I have carefully reviewed your project for developing an application for construction companies. I understand that you need a comprehensive solution with employee geolocation tracking, work time accounting, task management, chat, and an administrative panel.

I have extensive experience in developing mobile and web applications (over 5 years) and am confident that I can implement your project at a high level. Our team is proficient in a wide range of technologies, including React Native or Flutter for mobile development, and Laravel/Node.js/Django/FastAPI for backend and admin panel. We also have experience with database integration and data export to Excel. The design you provided looks well thought out, and we are ready to fully implement it both on the frontend and backend.

I suggest discussing the project details to clarify all requirements and to prepare a more accurate estimate and work plan. I will be happy to answer your questions and offer the best solution that considers all your wishes. Let's get in touch to start working!

Developed a time sheet management system with manual control + GPS geofencing, offline mode, and export to Excel

… Developed administrator panels with current employee locations, violation alerts, and exportable reports

Experience with role-based management panels for managers, workers, and administrators, including push/chat modules

Timelines:
MVP in 4–5 weeks

Final build with enhancements, export, and filters: 7–8 weeks

Cost:
$3500–$4000 fixed
Includes development, integration, testing, and support after launch for 1 month

Best regards,
Georgios Toutoudakis

Hello!
There is experience in implementing very similar functionality as part of a larger project. Therefore, we are ready to develop both a mobile application, a backend, and an admin panel.
We propose to develop the mobile application using Flutter for iOS and Android. The backend will be on Laravel. The admin panel on Laravel\Filament.
To provide an accurate estimate of the timeline and cost, a more detailed description of the application's functionality for each screen is needed. Or we can schedule a call to discuss all the details of this project.
Currently, the estimate is preliminary.

Hello,

Thank you for sharing the detailed requirements and Figma prototype — the scope is well-structured.

We at CJ Developers specialize in custom cross-platform solutions and can fully develop this construction time tracking app — with GPS logic, admin dashboard, automated reporting, and privacy controls — exactly to your specifications.

🔧 Our Proposed Tech Stack:
Mobile App (iOS + Android): Flutter

… Backend: Node.js + Express or Firebase

Database: PostgreSQL / Firestore (based on sync needs)

Admin Panel: React.js or Vue.js (web-based)

Authentication: Firebase Auth / JWT

Location Services: Google Maps SDK + Geofencing

Good day! Ready to complete the task. For clients, I will use Flutter, backend - Node.js + PostgreSQL/MySQL, or Firebase
