Full-Stack SaaS Developer: Build & Package "SMS LocalBlast" (Full Development + Documentation)
Budget: $250 – $750 USD
SMS BLAST MASTER
I am looking for a high-level Full-Stack Developer to build and fully package SMS LocalBlast, a white-label enterprise SMS gateway.
You will be responsible for the full lifecycle: from finalizing the Node.js/Excel architecture to creating the marketing and technical assets required for distribution launch.
Scope of Work:
1. Platform Development: Build a Node.js API that connects an Excel JS Add-in to mobile devices (Android/iOS) via a secure queue.
2. Enterprise Features: Implement Multi-Device Sync (load balancing), Smart Jitter (anti-spam delays), and a Web-based Installer (3-step setup wizard).
3. Security & Licensing: Build a Master License Server to validate purchase codes, track global installs, and implement a remote "Kill Switch" for pirated copies.
4. Auto-Updater: Configure GitHub Actions so clients can update their platform with one click from their Admin Dashboard.
Mandatory Deliverables (The "Sales Package"):
• The Live Demo Site: Set up and host a functional "Sandbox" version of the platform for potential buyers to test (with simulated sending).
• Professional Video Demo: A 3–5 minute high-quality screen recording with voiceover (or professional captions) demonstrating the setup, Excel integration, and mobile connection.
• Complete Documentation: A professional HTML/PDF "User & Developer Manual" covering installation, API usage, and troubleshooting.
• The CodeCanyon Zip: A perfectly organized folder ready for submission.
Technical Requirements:
• Backend: Node.js, Express, PostgreSQL.
• Frontend: Clean, modern UI (Tailwind or similar) matching my provided logo/branding.
• Add-in: Office JS API (Excel Desktop & Web).
• DevOps: GitHub Actions, PM2, SSL management.
