I am looking for a professional developer with advanced experience in AppSheet to finalize and polish an attendance management application (QR scanning access control) that I already have structured and working in its core logic. The base logic is created, but I need to optimize the interface (Dashboard, navigation, screen display) to ensure it is intuitive, clean, and professional. Full Workflow Automation, QR Generation, Automated Tracking and Deduction: Scans must be processed instantly, automatically updating the database to deduct sessions/tournaments from the participants' corresponding balances. SPECIFIC FUNCTIONS: Client Registration: Enrollment via a web form that automatically feeds data into the spreadsheet. Identification: Receipt of a unique and permanent QR code upon registration. Administrator (Spreadsheet - The Brain) Central Logic: The spreadsheet is the core system that processes and calculates everything. Session Management: Sessions are automatically deducted whenever a coach scans a player's QR code. Automatic Renewal: The system automatically renews classes every 30 days based on the original registration date (classes not used within the month expire). Custom Control: Ability to manually pause or freeze a player's QR code or sessions (e.g., for up to two weeks of vacation). Coach Scanning Interface: A dedicated view designed exclusively for scanning codes at matches or tournaments. Validation: Immediate feedback upon scanning indicating whether the player's access is granted or denied. Terms of collaboration: Budget: €100 (fixed, non-negotiable). Payment will be released only once the application is fully tested and functioning with full automation according to the requirements. Requirements: Proven experience in AppSheet and google Sheet, ability to work on an existing base, and a focus on clean design. If you have previous experience with these types of automations and data management with Google Sheets, I would like to know your availability to get started as soon as possible.

On one of our AppSheet automation projects, the formulas were already working, but the real bottleneck was the user experience and automation flow. We simplified the navigation, optimized the dashboards, and automated the Google Sheets updates so users no longer had to perform manual actions after each scan. The result was a faster, error-free workflow that the client could manage without ongoing technical support. We've built business automation solutions using AppSheet, Google Sheets, Apps Script, and QR-based workflows for internal operations and attendance management. For your application, I'll focus on polishing the existing solution rather than rebuilding it. That includes refining the UI/UX, automating QR generation for every participant, ensuring each scan instantly updates Google Sheets and deducts the correct session or tournament balance, validating the complete workflow, and preparing the application for stable day-to-day use. One question: Is the QR code simply linked to a unique participant ID, or does it already contain encrypted/session-specific information that must be validated during scanning? Thanks, Rajesh

Hi, A well-built AppSheet application isn't just about having the logic work—it also needs a clean interface and reliable automation to ensure every scan updates data accurately without manual intervention. I can help refine your existing app into a polished, user-friendly solution.

I'll focus on making the app intuitive, reliable, and fully automated while preserving your existing structure. A few quick questions: Is the current AppSheet app already connected to the final Google Sheet structure? Are there any specific automation issues that are still incomplete, or is the main focus on UI optimization? Will I be given access to a copy of the existing AppSheet project and spreadsheet? I'd be happy to share relevant AppSheet automation and Google Sheets integration projects during our discussion. Kindly initiate a chat so we can discuss your project in more detail. Best regards,

Your AppSheet attendance app sounds like it already has a solid base, and I can see you want that polished, professional finish on the dashboard and navigation. I have worked on similar QR-based access control systems, so I understand the importance of instant feedback and clean automation. For the interface, I would focus on making the coach's scanning view as simple as possible, with clear visual confirmation, and tidy up the admin dashboard so session tracking and freeze controls are easy to find. The logic you already have in the spreadsheet should stay as the backbone. I will provide unlimited revisions until you're completely satisfied. Best Regards, Azad
