Project Title: Mobile-Friendly Construction Operations App (Forms, Reports, Attendance, RMC Tracking) Project Overview We are a construction firm looking to hire an experienced Full-Stack Developer / App Development Team to build a mobile-friendly web app (and optionally Android app) for internal company use. The system will help us manage operations across multiple RMC plants and construction sites with centralized reporting, forms, attendance logging, tender tracking, and labor reports. The application must be secure, scalable, and optimized for mobile usage by our site engineers, plant staff, and admin team. --- Key Modules & Features Required 1. User Management & Authentication Secure login system (Role-based: Admin, Site Engineer, Plant Manager, Accountant, Labor Supervisor) OTP login optional Device-based access control Audit logs of all activity User creation & permission settings --- 2. Dynamic Forms Module We should be able to create, update, or disable forms without developer support. Forms include: Daily site report RMC dispatch form Material inbound register Diesel usage form Equipment breakdown form Expense entry form Any custom forms we add later Form features required: Custom fields (text, number, dropdown, file upload, geo-location, images) Capture GPS location Offline entry + auto sync Approval workflow (optional) --- 3. RMC Plant & Sites Dashboard A centralized dashboard for: RMC production & dispatch Site-wise consumption Material tracking (cement, aggregate, sand, water, admixture) Diesel tracking & breakdown Plant-wise output analysis Site-wise cost analysis Data should be viewable as: Tables Charts (bar, line, monthly comparison) CSV/Excel export --- 4. Attendance & Location Tracking Employee login & attendance with GPS location QR code / selfie option for verification Track workers assigned to each site Daily manpower report Timesheet for staff & labor --- 5. Tender & Billing Module For finance & admin team: Tender data entry Estimated vs actual expense report Running bill tracker Material procurement cost Payment received & deposit tracker Reports needed: Cashflow Tender progress Billing vs deposit vs pending Expense leakage detection --- 6. Labor Management Labor contractor database Daily labor deployment form Labor payment sheet Overtime & shift tracking Cost per labor category --- 7. Reports & Analytics The system should generate: Site-wise daily/weekly/monthly reports Plant performance reports Diesel usage & breakdown reports Expense control reports Labor productivity report Excel/PDF export Filter by date, site, RMC plant, employee Platform Requirements Mobile-friendly responsive web app Optional Android app (quote separately) Cloud database (Firebase / MySQL / PostgreSQL preferred) Admin control panel Security Secure authentication Encrypted data Access control by role Automatic backups Tech Stack Preference (Open to suggestions) React / Flutter / Vue / Next.js Backend: Node.js / Laravel / Python Django Database: MySQL / PostgreSQL / Firebase Hosting: AWS / Google Cloud You tell us the best solution for speed + scalability. Deliverables 1. Fully functional web application 2. Admin dashboard 3. API documentation 4. Hosting and deployment setup 5. 3 months post-launch support 6. Training for our team Who Can Apply Developers or agencies with experience in: Construction ERP Form builder apps GPS-based attendance Reporting dashboards Multi-site data management Mobile web apps Please share: Portfolio Timeline Estimate
