Web & Mobile Applications

User-facing applications delivered through browsers or mobile app stores. The largest and most diverse category — covers everything from a marketing site to a multi-tenant SaaS platform.

When to look here

  • The end user interacts with a UI (web, mobile, or both)
  • Most logic can live behind a request/response API
  • Acceptable latency is hundreds of milliseconds, not microseconds

LLM-development sweet spot

This is the category where AI-assisted development pays off the most. Patterns are heavily represented in training data, frameworks are mature, and the work is mostly composition rather than novel algorithm design.
