FAQ
What technologies do you use to build web apps?
I use modern full stack technologies such as React.js or Next.js for the frontend, Node.js with Express for the backend, and MongoDB or Firebase for the database. Apps are designed to be secure, scalable, and high-performance.
Can you create login systems with secure authentication?
Yes, I implement secure user authentication using JWT, Firebase Auth, or OAuth. I can also build role-based access dashboards for users, admins, or any custom roles you need.
Do you integrate payment gateways like Stripe or PayPal?
Absolutely! I can integrate Stripe, PayPal, or Razorpay into your web app, including payment forms, subscriptions, discount codes, and webhook handling for real-time updates.
Will the web app be mobile responsive?
Yes, every web app I build is fully responsive and works on all devices. I use modern CSS frameworks like Tailwind CSS to ensure a clean, responsive UI.
Can I see samples of your past work?
Of course! I’ve worked on apps like Livingly (apartment system), Gardenify (gardening app), and ShareBite (food sharing app). Message me and I’ll be happy to share demos or GitHub links.
