# Bugdr — Full Reference

## Product

Bugdr (https://bugdr.app) is a production bug-fixing platform for software
engineers. Problems on Bugdr are real bugs extracted from open-source GitHub
repositories — not hand-crafted puzzles. Each problem is a self-contained
Node.js codebase (no dependencies, no setup) that reproduces a real bug.
Engineers fix the bug and submit; automated Docker-based checks verify the
fix passes and the buggy version fails.

## Problem format

Each problem contains:
- A title and description explaining the bug and its real-world context
- A self-contained codebase (files the engineer can run locally)
- Hidden automated checks that validate the fix
- Metadata: difficulty, category, career path, points, source PR link

## Difficulty levels

- Easy (100 points): Clear, isolated bugs. Single function or small module.
- Medium (250 points): Multi-file bugs requiring understanding of interactions.
- Hard (500 points): Complex system bugs. Race conditions, edge cases, performance.
- Get a Job (1000 points): Staff-level bugs. Architecture issues, subtle regressions.

## Categories

JavaScript, TypeScript, Node.js, Python, Ruby, Go, Rust, PHP, Java,
Frontend, Backend, Full Stack, Mobile, DevOps/Infra, and more.

## Career paths

Frontend Engineer, Backend Engineer, Full Stack Engineer,
Mobile Engineer, DevOps / Infra Engineer, Staff Engineer.

## Why Bugdr vs LeetCode

LeetCode trains algorithm thinking. Bugdr trains debugging — reading
unfamiliar code, understanding context, isolating a fault, and writing
a targeted fix. These are the skills engineers use daily on the job
and in real technical interviews at product companies.

## Tech stack (for developers evaluating the platform)

- Frontend: Next.js 16, React 19, TypeScript, Tailwind CSS
- Backend: Node.js, Express 5, PostgreSQL 17
- Problem validation: Docker-based automated check runner
- Bug sourcing: GitHub PR scraper + AI enrichment pipeline

## Target audience

- Self-taught developers preparing for their first engineering job
- Junior engineers aiming for senior-level roles
- Engineers who want a portfolio of real debugging work
- Bootcamp graduates who need beyond-tutorial experience
