FAQ
Do you use the latest Next.js 15 features for development?
Yes! I specialize in Next.js 15, utilizing the App Router and Server Actions. As an expert front end developer, I ensure your mern stack application is lightning-fast, secure and follows 2026 industry standards.
Can you integrate MySQL/PostgreSQL instead of just MongoDB?
Absolutely. While many mern stack developers only know MongoDB, I excel in using NestJS with MySQL or PostgreSQL via Prisma ORM. This is ideal for complex full-stack business logic, SaaS platforms and better scalability.
Can you convert Figma, Adobe XD, or PSD designs into a functional app?
Yes, I provide pixel-perfect conversion. I will be your front end developer to turn any Figma or XD design into a fully functional nextjs or React application, ensuring it is fully responsive on all devices.
Will my website be SEO-friendly and have a high PageSpeed score?
Definitely. I implement SSR and SSG to ensure 90+ Google PageSpeed scores. My nextjs and mern stack solutions are structured to be highly crawlable, giving you a significant edge in SEO rankings.
What do you need from me to start the project?
I need a clear description of your requirements, any design files (Figma/XD), and your preferred tech stack. If you're unsure about the technical roadmap, just message me and we can finalize the details together.
Do you provide deployment and post-delivery support?
Yes, I provide full support for deployment on Vercel, AWS or DigitalOcean. I also offer technical support after the project is completed to ensure your web application runs smoothly and stays updated.
How do you handle complex data and ensure scalability?
I use Redux Toolkit or Zustand for professional state management. By following a Modular Clean Architecture, I ensure your web app remains fast, organized and easy to scale as your business and user base grow.
