Code review: what companies really look for in your GitHub

The first thing anyone reviews in your GitHub is the repository landing page: your README, your folder structure and your commit history. In roughly 30 seconds a reviewer decides whether your project feels serious. If the README is missing or generic, the review rarely recovers.

A README that explains what the project does, how to run it, and the decisions behind it is the single highest-leverage file in a portfolio.

• A clear, specific README that a stranger could follow
• A logical folder structure that matches the stack's conventions
• Meaningful commit messages that tell a story
• Tests that run and cover real behavior
• A deploy story: CI config, environment handling, documentation of release
• No obvious security red flags like committed secrets

Most portfolios are fine. The ones that stand out show deliberate decisions: a documented trade-off, a typed interface used consistently, a test that catches a subtle bug. These are signals of seniority because they prove judgment, not just syntax.

• Architecture decisions written down (why did you choose this pattern?)
• A growing test suite that protects the main flow
• Automated checks configured so the project can be deployed by anyone
• Accessibility and performance work that comes from care, not from a checklist

• No tests anywhere, especially for a full project
• A single commit containing the entire application
• Hardcoded credentials in source files
• Deprecated dependencies with no upgrade path
• Code that ignores the stack's conventions (the classic "JavaScript in a Go project style")

None of these are fatal on their own. Together, they suggest a project built under pressure and never revisited — which is exactly what you do not want to communicate before an interview.

RateYourProject automates this exact review. Upload your project, choose your role and seniority, and the analysis evaluates architecture, code quality, testing, documentation, deploy and best practices — the same dimensions a senior engineer mentally checks when they open your repository.
