When a web app is the right choice

A web app is not a website with login. It's a software product: it has users, data, roles, workflow, business logic. The difference is huge — both in time and costs.

Building a web app means thinking about:

  • Database — how you model data that lives over time
  • Authentication and authorization — who can do what
  • State management — how you handle data shared across users
  • Performance — how you scale at 100, 1k, 10k users
  • Security — how you protect sensitive data from OWASP Top 10
  • DevOps — how you deploy with no downtime

All these come from my full-stack + cybersecurity background, they're not "extras" but the foundation.
