This is a submission for the Gemma 4 Challenge: Build with Gemma 4

PR Sentinel analyzes React and TypeScript snippets and generates structured engineering feedback focused on maintainability, accessibility, performance, and UI quality.

What I Built

PR Sentinel is an AI-assisted frontend PR reviewer focused on React and TypeScript engineering quality.

Developers can paste frontend code snippets and receive structured engineering feedback across:

React best practices
Maintainability
UI/UX quality
Accessibility (A11y)
Component architecture
State management patterns

The project was inspired by real frontend review pain points commonly seen in enterprise applications, especially issues related to stale closures, infinite re-renders, semantic accessibility structure, and reusable component design.

Instead of producing generic AI summaries, PR Sentinel organizes feedback into categorized engineering review cards that resemble actual senior-level frontend review comments.

The application allows developers to paste frontend snippets and receive categorized AI-generated engineering review feedback in real time.

Key Features:

AI-powered React/TypeScript review analysis
Structured frontend engineering feedback
Accessibility-focused review insights
UI/UX and maintainability recommendations
Real-time review rendering

How I Used Gemma 4

PR Sentinel uses Gemma 4 to analyze React and TypeScript frontend code snippets and generate structured PR-style engineering feedback.

The project focuses on identifying practical frontend issues such as:

infinite render loops
stale closures in async logic
unsafe DOM access patterns
maintainability concerns
accessibility-related frontend risks

Gemma 4 was selected because the project required fast reasoning over frontend engineering patterns while generating concise, developer-focused review output.

The model is used to evaluate pasted code snippets and return structured recommendations similar to a lightweight frontend pull request review workflow.

The application includes built-in diagnostic sandbox scenarios that simulate real frontend engineering issues commonly encountered in React applications.
