FAQ
Q1. What technologies do you use for website development?
I mainly use React.js, Next.js, Node.js, Nest.js, PHP LARAVEL,WordPress, Shopify, PostgreSQL, MongoDB, and Redis for full stack development. Depending on project needs, I can also work with TypeScript, Docker, and AWS for deployment.
Q2. Can you build both frontend and backend for my website?
Absolutely. As a full stack developer, I handle everything — from frontend UI/UX design and API integration to backend logic, authentication, and database setup.
Q3. Do you provide custom design or use templates?
I create fully custom designs tailored to your brand and requirements. However, if you prefer using a UI kit or template, I can adapt it and optimize it for performance.
Q5. Do you offer maintenance or post-launch support?
Yes, I provide free support after delivery for minor fixes and adjustments. For ongoing updates, we can set up a maintenance package at a discounted rate.
Q6. How do you ensure security and scalability?
I follow industry best practices — secure authentication (JWT/OAuth), input validation, API rate limiting, and clean, modular code to ensure your app scales safely as traffic grows.
Q7. Can we discuss the project before ordering?
Definitely! Please message me and have call before placing an order so we can align on your goals, requirements, and delivery timeline. This helps ensure smooth collaboration and perfect results.
