FAQ
Do you build the full stack web application from scratch or use templates?
Every application is handcrafted from scratch using clean, module-based architecture. Whether utilizing a react node js setup or a next js developer workflow, your codebase will be unique, highly maintainable, and customized exactly to your functional specifications.
How do you handle real-time features and live updates?
I use WebSockets (via Socket.io) coupled with state management solutions like Zustand or Redux. This allows your app to push updates to users instantaneously without manual page refreshes, which is perfect for chat applications, real-time dashboards, or live notifications.
Will the application support automated billing and subscription changes?
Yes, I set up absolute end-to-end payment workflows using Stripe Webhooks. This ensures that when a user subscribes, pays, cancels, or fails a payment, your system securely listens to the webhook events and updates the database instantly.
Can you work with existing codebases or clean up legacy code?
Absolutely. If you have an existing application running on Node.js or Next.js that needs bug fixing, optimization, or a database migration using Prisma or Mongoose, send me a message. I can audit your current architecture and refactor it smoothly.
Will You support after complete the project?
Definitely, If you need any help then Feel free to send me a message. I will try to give my best.
