FAQ
Why do you use Fastify and PostgreSQL instead of the standard MERN stack?
Fastify is a low-overhead framework that runs up to 3x faster than Express, significantly reducing server latency. PostgreSQL is a powerful relational database, which is essential for handling the complex data structures, multi-user roles, and precise data connections required in professional CRMs a
Can you build multi-tenant SaaS applications?
Yes, absolutely. I can architect a multi-tenant system where multiple businesses can register, manage their operations, and access independent data spaces securely under a single application infrastructure, perfect for subscription-based business models.
Will I get the complete source code, and is it well-structured?
Yes, you will get 100% ownership of the clean, production-ready, and well-documented source code. I follow strict architectural patterns using clean folder structures, optimized API routes, and reliable database indexing.
Do you assist with cloud deployment and production setup?
Yes, I can help deploy your Next.js frontend and Fastify backend to premium cloud hosting platforms like AWS, DigitalOcean, Vercel, or VPS platforms, ensuring proper security headers and database backups are configured.
My project requirement is highly complex. Can we do a custom order?
Definitely. Business applications like custom ERPs often require tailored planning. Please use the "Contact Me" button to share your feature list or wireframes, and I will create a highly precise custom milestone-based offer for your project.
