My Portfolio
FAQ
Do you build custom web applications or use templates?
I write 100% custom code using modern technologies like Next.js, React, Node.js, and MongoDB. I do not use pre-built templates or WordPress. This ensures your SaaS or web app is highly scalable, fast, secure, and tailored to your exact business needs.
Do I need to provide the UI/UX design, or do you handle it?
If you have a Figma design, that is perfect! If not, don't worry. I can design a clean, modern, and highly responsive UI using Tailwind CSS based on your project requirements before starting the core development phase.
Can you build a multi-role admin dashboard with payment integration?
Absolutely. I specialize in building complex system architectures. I can implement secure role-based access control (e.g., Admin, Vendor, User) and integrate secure payment gateways like Stripe or PayPal for your SaaS platform.
What happens if I find a bug after the project is delivered?
Client satisfaction is my ultimate priority. I provide 30 days of free support after the final delivery. If any bugs or technical issues arise regarding the features we agreed upon, I will fix them promptly at no extra cost.
Will you help me deploy the application to a live server?
Yes, complete deployment is included! I will set up the hosting and deploy both your frontend and backend (using platforms like Vercel, Netlify, or your preferred VPS) so your application is 100% live and ready for your users.
