What is Tech Stack?
The combination of programming languages, frameworks, tools, and services used to build an application.
Why It Matters
Choosing the right tech stack affects development speed, hiring, performance, and long-term maintenance costs.
Real-World Example
A common modern stack: Next.js for the frontend, Node.js for the backend, PostgreSQL for the database, deployed on Vercel.
“Understanding terms like Tech Stack matters because it helps you have better conversations with developers and make smarter decisions about your software. You do not need to be technical. You just need to know enough to ask the right questions.”
