AI Code Review Bot
Problem
Pull request reviews were taking too long for routine quality checks, creating feedback bottlenecks across active repositories.
Solution
Built a GitHub App service that processes pull request webhook events, analyzes diffs with OpenAI APIs, and publishes structured review comments automatically.
Architecture
Used installation-scoped GitHub authentication for secure multi-repo operation.
Enforced webhook signature verification to protect inbound event handling.
Designed diff parsing and prompt construction to keep responses relevant while controlling token usage.
Containerized the service with Docker for predictable deployment and scaling.
Outcome
Enabled fast first-pass reviews with consistent, actionable feedback and production-ready deployment behavior.
