Your resume should list wins. Not duties.

A friend had five years of experience. His resume was boring. It said responsible for maintaining services.

We rewrote it. We used strong verbs. We added numbers.

• Reduced API response time by 40%.
• Used Redis caching.

He got the interview.

You want to automate this. Simple AI prompts create generic text. You need a structured pipeline.

Use LangChain and Node.js.

LangChain is like Express for AI. Raw API calls get messy. LangChain organizes your prompts and chains.

The system works in three steps.

• Parse the resume into sections.
• Run a specific prompt for each part.
• Return the results.

Tips for better results.

• Give the AI a role. Call it an expert resume coach.
• Set a low temperature. Use 0.4 for accuracy.
• Limit the output. Ask for exactly four bullet points.

Avoid these mistakes.

• Do not let AI invent numbers. Tell it to use only existing data.
• Do not send too much text. Truncate the resume to save money.
• Use gpt-4o-mini. It is cheaper and fast.
• Stream the response. Users hate waiting for a blank screen.
