FAQ
Do you use TypeScript or only JavaScript for MERN development?
am proficient in both JavaScript (ES6+) and TypeScript. I can build your project in TypeScript upon request; just mention it before ordering so I can set up the project accordingly. The default packages are in JavaScript, but I can adapt easily.
I already have a backend/database. Can you build only the frontend in React?
Absolutely. I can integrate your existing REST API or GraphQL backend with a brand-new React frontend. I can also work on just the Node.js backend if you have a frontend ready. Just share your API documentation with me.
How do you ensure the security of my web application?
I implement multiple security measures: password hashing (bcrypt), JWT token-based auth, input validation, CORS configuration, secure HTTP headers and environment variables for sensitive data. For Premium projects, I also add rate limiting and XSS protection. Your data security is my priority.
Do you sign NDAs (Non-Disclosure Agreements) for confidential projects?
Yes, I respect your privacy. If your project is sensitive, just send me the NDA document via Fiverr messages before placing the order. I’ll sign it digitally, keeping your idea completely secure.
How often will you update me during the development process?
I believe in transparent communication. You will get daily updates or progress screenshots. For larger projects, I can share a staging link so you can see the app in action before final delivery. You'll never feel left in the dark.
