Code Review Best Practices: Speed and Quality for Startup Engineering

Code reviews prevent bugs, spread knowledge, and maintain quality—but slow reviews block progress. These code review best practices balance speed and rigour with small PRs, automation, and async-first workflows.

Key takeaways

PRs >400 lines rarely get thorough review; split into smaller chunks.

Automated checks (lint, test, type coverage) catch 80% of issues before human review.

Review SLA: first response <4 hours, approval/changes <24 hours.
