Show HN: I Used AI to Fight ATS Rejection – 500 Signups in 5 Days

ResumeAdapter.com - Instant ATS Optimization for Tech Roles

The Problem:

72% of dev resumes get rejected by bots before human review (Source)

Juniors waste hours guessing keywords like "Kubernetes" vs "Docker Swarm"

The Build:

Stack: Bolt.new (React) + Firebase + GPT-4-Turbo

Shipped MVP in 72 hours using AI-generated code (38% of codebase via Cursor.sh)

Traction:

522 signups (83% juniors)

4.7% conversion to $9.99/mo tier

22% returning users (7-day retention)

Hard Lessons:

PDF parsing costs 60% of dev time (finally used PyMuPDF)

Free-tier users convert best after 3 analyses (now gatekeeping earlier)

Devs care more about keyword gaps than design ("Just tell me what to add!")

Ask HN:

How would you improve the technical implementation?
