ResuMatch

Smart Resume-Job Matching Platform

Visit Live AppTimeline: 3 weeks from concept to production

The Problem

Job seekers submit the same resume to hundreds of postings without knowing if they're a good match. Recruiters waste time reviewing unqualified applications. There's no quick way to get honest, actionable feedback on resume-job fit.

The Solution

ResuMatch lets users upload a resume and paste a job description to get an instant AI-powered compatibility score with specific, actionable suggestions. It highlights matching skills, missing requirements, and gives concrete improvement tips — like having a senior engineer review your resume in seconds.

My Approach

1

Built a clean, step-by-step UI: upload resume → paste job description → get results

2

Implemented PDF parsing on the backend to extract resume text reliably

3

Designed Claude AI prompts for structured scoring (0-100) with category breakdowns

4

Added Google OAuth for saved history and Razorpay for premium features

5

Created SES-based email notifications for match results

6

Deployed fully serverless with zero fixed infrastructure costs

Architecture

Challenges & Solutions

Lessons Learned

  • Presigned S3 URLs are the cleanest pattern for file uploads in serverless — no Lambda payload limits
  • Claude AI with structured output mode dramatically reduces parsing complexity
  • Google OAuth with DynamoDB session management is simpler than Cognito for small apps
  • Razorpay integration was surprisingly clean — their API design is excellent for Indian market payments
