Both are full-stack development solutions. MERN Stack uses React (flexible, component-based), while MEAN Stack uses Angular (enterprise-focused, TypeScript-native). We help choose based on your project requirements.

Do you use TypeScript in Node.js projects?

Yes, TypeScript is increasingly our standard for Node.js development, especially with Nest JS and MEAN Stack. It provides type safety, better tooling, and improved maintainability.

How do you handle real-time features?

We implement real-time applications using Web Sockets and Socket.IO, leveraging Node.js‘s event loop and non-blocking architecture for efficient bi-directional communication.

Which cloud platform do you recommend? 

We deploy across AWS, Azure, and Heroku. AWS offers most flexibility, Azure integrates well with Microsoft ecosystems, and Heroku provides fastest time-to-market. We recommend based on your specific needs, budget, and DevOps capabilities.
