Build Real-Time QR Attendance Monitoring System (2-Week MVP) – Multi-Location Dashboard Project Overview We are looking for a developer to build a lightweight MVP system for real-time attendance monitoring across multiple client locations. The system will be used by operational teams to check in and check out via QR codes at each location, with a live dashboard displayed 24/7 on an office TV screen. This is a production pilot with approximately 12 locations. Delivery required within 14 days. Core MVP Requirements 1. Location-Based QR Check-In / Check-Out Each client location must have: • A unique Check-In QR code • A unique Check-Out QR code When scanned, the QR opens a simple mobile web page where the user confirms the action. The system logs: • Location ID • Scan type (IN / OUT) • Timestamp (automatic) • User or team identifier (optional) 2. GPS / On-Site Verification (Anti-Fraud) Each scan must include basic location verification: • GPS permission required • Scan must occur within a defined radius of the location (e.g., 100m) • If GPS fails or is outside radius, scan should be flagged as “unverified” This ensures reliable proof-of-presence. 3. Real-Time Office Dashboard (TV Screen View) We need a single live monitoring screen showing all locations: • Green = Checked-In (active) • Red = Checked-Out or not currently active • Optional warning icon if scan unverified Dashboard should display: • Location name • Current status (IN / OUT) • Last check-in time • Last check-out time The dashboard must update in real time or auto-refresh every 10–30 seconds. Designed for large TV visibility (simple, high contrast, big font). 4. Web Hosting Under Client Domain The system must be accessible via a URL that can be linked from an existing business website, such as: /attendance or /monitor Dashboard must not be publicly accessible: • Secure view-only link OR monitor login role 5. Admin Setup Panel (Basic) Admin must be able to: • Add/edit locations (approx. 12) • Generate QR codes for each location (IN and OUT) • View scan logs No complex HR features required. Technical Preferences Preferred stack: • Firebase (Firestore + Hosting) • React / [login to view URL] or similar • Mobile-first web app (PWA optional) • Real-time database updates System should be scalable to 50+ locations later. Timeline Requirement MVP must be delivered within: 14 days Please apply only if you can commit to this timeline. Deliverables After 2 Weeks Working QR check-in/out system for 12 locations GPS radius verification Real-time dashboard (TV-ready) Secure hosted monitoring URL Admin location + QR management Full source code + documentation When Applying, Please Answer: 1. Can you deliver within 14 days? Provide your plan. 2. Have you built QR-based attendance or location verification systems before? 3. What stack will you use? 4. How will you implement GPS validation securely? Note This MVP will expand into a larger operational performance platform after successful pilot deployment.

I have experience building real-time, location-based systems and can deliver your QR attendance MVP within 14 days. I will create unique check-in and check-out QR codes for each location with GPS verification to ensure scans occur on-site, logging all activity accurately. A live dashboard optimized for TV displays will update in real time, showing IN/OUT status and alerts for unverified scans. The system will include a secure admin panel to manage locations, generate QR codes, and view logs, all hosted under your domain with scalable architecture for future expansion. Deliverables include fully functional mobile web check-in/out, GPS verification, real-time dashboard, source code, and documentation.

Based on your requirements, this project goes beyond a basic QR tool. It’s a real time attendance monitoring platform with GPS validation, multi location control, and a live TV dashboard built for operational visibility. My plan 1) Set up the Firebase project, design the Firestore database structure, and configure secure hosting under your domain with proper role based access for admin and monitor views. 2) Build the QR based check in and check out system for each location, including unique QR generation, scan confirmation flow, and automatic logging of timestamp, location ID, and scan type. 3) Implement GPS validation using browser geolocation API, compare coordinates against predefined location radius, and flag scans as verified or unverified based on distance logic. 4) Develop a real time monitoring dashboard optimized for large TV screens, showing live IN or OUT status, last activity timestamps, and visual indicators for unverified scans with auto refresh fallback. 5) Create an admin panel to add or edit locations, generate QR codes dynamically, and review scan logs If this works for you, I’ll start with the database schema and QR flow, then integrate GPS validation and finalize the real time dashboard and admin controls for deployment within the 14 day timeline.

Hi there, I am a strong fit for this MVP because I have built real-time QR and location-verified workflow systems with live monitoring dashboards and secure role-based access. I have implemented QR-based check-in flows, GPS radius validation using browser geolocation APIs, real-time Firestore updates, and TV-ready monitoring dashboards with auto-refresh and status indicators. I recommend React with Firebase Hosting and Firestore for real-time sync, Firebase Auth for secure admin and monitor roles, and server-side validation via Cloud Functions for GPS radius enforcement. I reduce risk by validating geolocation server-side against stored coordinates, logging verification flags, isolating admin routes, and structuring the system for future scaling beyond 50 locations without schema redesign. I can deliver within 14 days with a staged rollout plan and am ready to begin immediately. Regards Chirag

Hi, I confirm I can deliver in 14 days (ex. weekends) - The system will be capable of handling unlimited locations and unlimited users data. No restrictions on these unless you need these in MVP. My preferred tech stack is PHP/Laravel for the web part + admin and Flutter or Objective C + Java Kotlin for Native mobile apps. Is your budget flexible as I think it is not inline with the scope of work and efforts needed to deliver in tight deadline of 2 weeks? I envisage €1500 - €2000. We can lock this amount once we can discuss in detail in a call / chat here on freelancer. I am a senior web and mobile app developer with 18 years of experience, specializing in ERP integration and social media strategies. I look forward to discussing the timeline and scope of this project further. Regards, Mohammad.
