Code Review Best Practices: Speed and Quality for Startup Engineering
Balance code review speed and quality with small PRs, automated checks, clear feedback frameworks, and async-first workflows for distributed teams.
TL;DR
- Small PRs (<400 lines) reviewed 5× faster than large PRs (>1000 lines).
- Automate style enforcement (Prettier, ESLint); focus reviews on logic and architecture.
- <24 hour review SLA prevents blocked developers and context loss.
# 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.
