🚀 I Built MAZ3R: An Open-Source AI Career Assistant for Resume Optimization & Cover Letters

This is a submission for the Hacktoberfest Weekend Challenge: Build for a Friend

What I Built

Job searching often means rewriting the same resume repeatedly for different positions, trying to understand ATS systems, and spending hours crafting cover letters.

To solve that problem, I built MAZ3R, an AI-powered platform that helps users:

  • Upload a resume (PDF or DOCX)
  • Paste a job description
  • Analyze ATS compatibility
  • Identify missing skills and keywords
  • Receive resume improvement recommendations
  • Generate a customized cover letter
  • Export reports and application documents

The project was designed for students, interns, fresh graduates, and job seekers who want to improve their applications without manually tailoring every document from scratch.
