Frequently asked questions
What is MERN stack development?
MERN stands for MongoDB, Express.js, React, and Node.js, a full JavaScript stack used to build modern, scalable web applications from front to back.
How long does a MERN stack project take?
A typical MVP takes 6 to 12 weeks. Larger enterprise applications can take 3 to 6 months depending on complexity, integrations, and feature scope.
Can you migrate my existing app to MERN stack?
Yes. We offer legacy application modernization services, migrating apps from PHP, .NET, or other stacks to a modern MERN architecture with minimal downtime.
Do you use TypeScript?
Yes. We use TypeScript across the front end and back end where it helps keep larger codebases maintainable.
When is MERN not the right choice?
For heavily relational, transaction-heavy systems, a SQL database is often a better fit. We recommend the stack from your data and your team, not by default.
