Designing, building, and maintaining software.
Answer five questions about Software Engineering and get instant feedback.
What describes something someone needs the software to do?
Good requirements are clear and testable, like "When I click Save, the app stores my changes within 2 seconds", so the team can build it and verify it works.
The big picture of how a system is put together
Architecture is the set of big design decisions, like splitting a system into services and choosing how they communicate, that shapes performance, reliability, and how easy it is to change later.

A branch lets work diverge from the main code line without immediately disrupting it.

A monolith keeps one codebase together, simplifying some changes while coupling many functions.
A codebase becomes easier to change when many parts depend on hidden assumptions.
A codebase becomes harder to change when many parts depend on hidden assumptions. Hidden assumptions create tight coupling across modules, so a small change triggers cascading breakage; making assumptions explicit via contracts, types, and focused tests restores safe, local reasoning.
