FAQ
Do you build both frontend and backend?
✅ Yes! I build complete fullstack apps using Next.js and Tailwind CSS for frontend, and Node.js, WebSockets, PostgreSQL, Redis, and Prisma for backend. I focus on functionality, not complex visual designs.
Will you work on existing projects?
✅ Yes! I can join your current project, fix bugs, add features, or improve backend and real-time logic. I’m comfortable collaborating via GitHub pull requests or other version control methods.
Can you add real-time features like live chat or auctions?
✅ Absolutely. I specialize in real-time apps using WebSockets and Redis, including live bidding, chat, and dashboards with reconnect-safe state handling.
Do you provide authentication and user login systems?
✅ Yes. I can implement secure authentication using NextAuth or build a custom session-based system with database integration.
Will the UI look good and modern?
✅ I use Tailwind CSS to build clean, functional interfaces. If you need advanced UI/UX design or animations, you may want to pair this with a UI designer.
How will I receive the completed website or code?
✅ I’ll deliver the full source code as a ZIP or via GitHub, including frontend/backend files, .env.example, and a README with setup instructions. If you have an existing project, I can contribute via GitHub pull requests to help you seamlessly integrate new features.
