FAQ
Can you work on both frontend and backend (full stack)?
Yes, absolutely. I offer full stack services: not only designing / building the frontend with React / Next.js, but also creating APIs, integrating databases (MongoDB), handling server logic in Node.js, setting up authentication, and deploying the final app.
How do you ensure your web app is fast and SEO-friendly (especially with Next.js)?
For SEO, I use Next.js’s server-side rendering (SSR) or static generation (SSG) to ensure proper metadata, clean URLs, and fast page load. I also optimize images, minify CSS/JS, lazy load components where possible. Caching and code splitting are used to reduce bundle sizes.
How do you handle responsive design and cross-device compatibility?
I build using mobile-first or responsive design approach, testing on different screen sizes (mobile, tablet, desktop). I use Tailwind CSS’s utility classes (or other CSS frameworks) to ensure layout, spacing, and style adapt well. I also check in multiple browsers to make sure it's functionality.
Do you work with existing projects?
Yes, I can debug and improve existing React or Next.js projects.
Do you fix React and Next.js errors?
Yes, I can debug and fix errors in React.js, Next.js, Node.js, and MERN stack applications.
