Hi, this is a serious product build, not just a coding task - you need a full-stack developer who can package SMS LocalBlast as a launch-ready white-label platform with both the technical core and the commercial delivery assets done properly. What stands out here is the combination of Node.js backend architecture, Office/Excel add-in integration, device sync, licensing/security, updater flow, and final sales packaging. I’d approach this in phases: - build the Node.js + PostgreSQL + Express core with secure queue handling between the Excel JS add-in and mobile devices - implement enterprise features like multi-device sync, jitter/rate controls, installer flow, licensing, and update pipeline - create the polished delivery package: sandbox demo, documentation, submission-ready structure, and launch assets I’m comfortable with Node.js, admin/dashboard systems, API design, PostgreSQL, Tailwind-based UI, GitHub Actions, and deployment workflows, and I understand the importance of building something clean enough for distribution, not just internal use. The value here is not only making the software work, but making it feel like a real commercial product buyers can install, trust, and update. If you want a developer who can help turn this into a launch-ready platform, I’d be glad to discuss the scope and milestones. Best regards, Diah

Hi, Building a white-label SMS gateway + sales-ready package—this is exactly my lane. I’ve built Node.js systems with queues, licensing servers, and full product packaging for launch. I’ll deliver a scalable API (Node + PostgreSQL), Excel JS add-in integration, multi-device sync, smart throttling, licensing + kill switch, and one-click updates via GitHub Actions—plus demo site, video, docs, and CodeCanyon-ready bundle. Can you share your preferred SMS routing method (device-based vs API providers)? Ready to start and handle this end-to-end. Thanks

As an experienced full-stack developer working with JavaScript, Node.js, and Express for over 7 years, I consider myself an ideal candidate for your project. My proficiency in both frontend and backend technologies will allow me to build your SMS LocalBlast platform while ensuring a consistent and modern UI/UX design in line with your brand guidelines. Also, my familiarity with the Office JS API will help in creating seamless Excel integration. Throughout my professional journey, I have gained expertise in API development, optimizing performance, and building scalable architectures. These skills will come particularly handy while implementing the enterprise features such as multi-device sync and smart jitter you require. Moreover, I am well-versed in developing secure systems, which aligns precisely with your need for a Master License Server to prevent unauthorized usage. In terms of deliverables, not only can you expect a well-documented user & developer manual covering all aspects from installation to troubleshooting but also a perfectly organized CodeCanyon zip ready for submission. Additionally, I can create a fully-functional sandbox demo version hosted on a secure server for potential buyers' testing purposes. I have a proven track record of enhancing projects with efficient GitHub Actions and can tighten your platform's security using SSL management and PM2.

⭐⭐⭐⭐⭐ ✅Hi there, hope you are doing well! I have previously developed a full-stack SaaS solution integrating Node.js APIs with Excel add-ins to enable seamless mobile device communication and user-friendly interactions. The key to successfully completing this project is ensuring robust, secure synchronization across devices while maintaining an intuitive, clean user interface. Approach: ⭕ Finalize the Node.js/Express backend with PostgreSQL database for reliable data management. ⭕ Develop the Excel JS Add-in to enable smooth communication and integration. ⭕ Implement enterprise features including Multi-Device Sync, Smart Jitter, and a Web-based Installer wizard. ⭕ Build a Master License Server for purchase validation, piracy control, and remote kill switch. ⭕ Set up GitHub Actions for automated updates. ⭕ Deliver the full sales package: live sandbox demo, professional video walkthrough, comprehensive HTML/PDF documentation, and ready CodeCanyon submission ZIP. ❓ Can you share any specific branding guidelines or design assets for the UI customization? I am confident in delivering a polished, enterprise-grade SMS gateway platform that meets all your technical and marketing needs effortlessly. Looking forward to your reply. Best regards, Nam

@SmartCodeDev

Hey! This sounds like a really ambitious project, and I’m confident I can handle it end-to-end. I’d build the Node.js backend to power the Excel JS add-in, connect it securely to Android/iOS devices, and implement enterprise features like multi-device sync, smart jitter, and the 3-step web installer. On the security side, I’d set up the master license server, remote kill switch, and automated updates via GitHub Actions so clients can update seamlessly from the dashboard. For the “sales package,” I can get the live demo site up with simulated sends, produce a polished 3–5 minute video demo with captions/voiceover, and create professional user/developer manuals. The final CodeCanyon zip would be clean, well-organized, and ready for submission. Tech stack would stick to Node.js + Express + PostgreSQL for the backend, Tailwind-based modern frontend, Office JS for the Excel add-in, and PM2/GitHub Actions for deployment and updates. I’ve done similar enterprise-grade integrations before, so I can see this through from architecture to launch.
