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

Key practices I

• Branch-per-feature model – Each developer works on isolated branches.
• 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:

t 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.
