How to Choose Your Tech Stack

1. Consider Your Requirements

• Real-time features? → Node.js
• Data processing? → Python
• Enterprise? → .NET or Java
• Rapid development? → Python or Node.js

2. Consider Your Team

• JavaScript developers? → React + Node.js
• Python developers? → Django + React
• .NET developers? → .NET + Angular

3. Consider Scalability

• Small app? → Any stack works
• Medium app? → Node.js or Python
• Large app? → Java or .NET
• Massive scale? → Serverless or microservices

4. Consider Performance

• High performance? → Java, .NET, or Go
• Good performance? → Node.js or Python
• Real-time? → Node.js

5. Consider Cost

• Startup budget? → Open source stack (Node.js + React + PostgreSQL)
• Enterprise budget? → .NET or Java
• Serverless? → Pay-per-execution (cheapest at scale)

FAQ

What's the best tech stack?

There's no "best" stack. The best stack depends on your requirements, team, and budget. We recommend MERN for startups and .NET for enterprises.

Can I change tech stack later?

It's possible but expensive. Choose wisely upfront. We can help you make the right choice.

What about security?

All modern frameworks have security best practices. We follow OWASP guidelines and implement security from day one.

What about performance?

Performance depends on architecture, not just technology. We optimize for performance regardless of tech stack.
