Before making this repository public, you must rotate the following credentials that were previously committed to git history:

1. GROQ_API_KEY - Generate a new API key from Groq Console
2. BLOB_READ_WRITE_TOKEN - Generate a new token from Vercel Dashboard → Storage → Blob
3. DATABASE_URL - Consider rotating the database password in Neon console (optional but recommended)

All sensitive configuration is stored in environment variables. Never commit:

• .env files
• API keys
• Database connection strings with credentials
• Tokens or secrets

Set these in Vercel Dashboard → Project Settings → Environment Variables:

• DATABASE_URL - PostgreSQL connection string (from Neon or your database provider)
• LLM_PROVIDER - Either groq or openai
• GROQ_API_KEY - Your Groq API key (if using Groq)
• OPENAI_API_KEY - Your OpenAI API key (if using OpenAI)
• BLOB_READ_WRITE_TOKEN - Vercel Blob storage token (optional, for resume storage)

1. Copy .env.example to .env
2. Fill in your actual credentials (never commit .env)
3. The .env file is already in .gitignore

• .env and .env.local files
• node_modules/
• uploads/ directory (local file storage)
• Any files containing API keys or secrets

Before making this repo public:

1. ✅ Rotate all exposed credentials (see above)
2. ✅ Verify .env.example contains only placeholders
3. ✅ Ensure .gitignore includes all sensitive files
4. ✅ Update Vercel environment variables with new credentials
5. ✅ Test that the app still works on Vercel after rotation

The app will continue to work on Vercel after making the repo public because:

• Environment variables are set in Vercel Dashboard (not in the repo)
• The code reads from process.env which Vercel injects at runtime
• No secrets are hardcoded in the source code
