How do you manage multiple contributors working on the same codebase?

Short answer: Key practices I Branch-per-feature model – Each developer works on isolated branches.

Explain a bit more

Pull Requests (PRs) for merging into main. Code reviews + CI tests required before merging. Protected branches prevent direct commits. Communication – Sync via Slack, GitHub Discussions, or standups to avoid conflicts. Example: At a fintech startup, 8 engineers worked on a single monorepo. We used short-lived branches and daily merges, with GitHub Actions running automatic tests for every PR — this reduced integration headaches.

Real-world example (ShopNest)

ShopNest’s team uses GitHub PRs with reviews and CI checks so broken builds never reach production unnoticed.

1. Define — one clear sentence (the short answer above).
2. Example — relate it to a project like ShopNest or your real work.
3. Trade-off — when you would not use it.
