Hi, I checked your "Full-Stack SaaS Project Manager" project and it looks like understanding the existing workflow will be important before making any changes. I've worked on similar PHP projects involving php, javascript, project management, mysql, node.js, angularjs, react.js, full stack development, database design, api development and prefer delivering work in small milestones so everything stays easy to review and adjust if needed. If you can share a few more details about the current setup and expected outcome, I'll suggest the best approach and provide an accurate timeline. ⭐ 5.0/5 from a recent client: "Project was delivered before Time with Best professional Knowledge One could ever held. Thanks for the support" Final timeline and cost will be confirmed in chat after a complete understanding and documentation of the project expectations in detail.

Your multi-tenant architecture will fail if you don't separate business data at the database level from day one. Retrofitting tenant isolation after launch means rewriting your entire schema and risking data leaks between customers. Quick questions - are you planning row-level security in PostgreSQL or separate schemas per tenant? And what's your target for concurrent businesses before you need to shard? Here is the architectural approach: - NODE.JS + POSTGRESQL: Build a modular monolith with feature flags so new modules (QR, rewards, analytics) deploy without touching core auth or billing logic. - REACT.JS + TAILWIND: Design a component library with shared layouts for business and admin dashboards to maintain UI consistency as modules scale. - STRIPE API + JWT: Implement webhook-driven subscription state management so payment failures trigger automated email sequences and dashboard lockouts without manual intervention. I've built 4 SaaS platforms that scaled past 10K users without architectural rewrites, including a multi-tenant analytics tool processing 2M events daily. Let's schedule a 20-minute call to review your database schema before you commit to a structure that won't support your roadmap.

I can design the scalable database architecture for the UHATO platform to support future modules without rebuilding the system. My first step will be to outline the database schema based on your requirements and confirm the specific functionalities you want to prioritize.

< Hi — Abror-Yakubov here from Uzbekistan >, "SCALABLE SAAS PLATFORM MVP" — you need a modular system that can grow with QR, subscriptions, analytics and more. I will build the backend with Node.js, Express and PostgreSQL, containerize everything with Docker, and deliver the frontend using React.js/Next.js and Tailwind CSS for a fast, responsive UI. I recently delivered a complex Modbus TCP Device Simulator using Node.js and Python, proving I can handle real‑time, secure back‑ends. To keep the platform multi‑tenant, I’ll design the database schema and JWT/OAuth auth so new modules plug in without code changes, and set up AWS deployment with CI/CD for smooth scaling. Which payment gateway do you prefer to integrate, and do you have a specific cloud provider in mind for hosting?
