Backend Dev for Smart Registration QR Queue System
Budget: $250 – $750 USD
Title:
Backend Developer Needed – Complete & Deploy Smart Registration + QR + Queue System (Frontend & Logic Ready)
Project Description:
I’ve developed a system in Lovable.ai that combines:
User registration
QR code generation & verification
Queue management
Payment handling
The frontend is fully complete, and about 85% of the logic is done. Now, I need an experienced backend developer to make the system fully functional, finalize key integrations, and deploy it both locally and in the cloud.
What I Have Ready:
Frontend UI is completed in Lovable.ai
85% of system logic is already built and mapped
Process flow is fully defined (registration → queue → QR → payment → verification)
What I Need From You:
Build the backend functionality using a technology stack that works well with SQL Server
Create and configure the SQL Server database schema
Set up two environments:
Local deployment on Windows Server
Cloud deployment for QR verification & API services
Enable two-way smart data integration between local and cloud via secure REST APIs
Final touches on any remaining frontend elements (optional but helpful)
Ensure the system is secure, fast, and stable
Key Features:
Registration system with unique QR generation
Queue management with live screen display
Offline registration on local server
Online QR verification via cloud system
Payment tracking and ticketing
Two SQL Server databases (local/cloud) synced via API
Deliverables:
Fully working backend connected to SQL Server
Local deployment on Windows Server (ready to use)
Cloud deployment (for verification and API access)
Integrated syncing logic between the two databases
Brief technical documentation for future updates
Preferred Skills:
.NET Core / C# backend (or Node.js with SQL Server experience)
SQL Server (T-SQL, stored procedures, etc.)
RESTful API design and integration
QR code systems (generation and scanning)
Experience with Windows Server deployment (IIS, firewall, etc.)
Familiarity with queue systems or smart workflows
If you’ve worked on similar systems (registration, queueing, QR verification, hybrid deployments), I’d love to see your portfolio. Looking to start immediately.
