You've moved beyond just playing with ChatGPT. You've integrated LLMs into real applications, dealt with hallucinations in production, and probably learned that the 'perfect prompt' you crafted breaks on edge cases. That hands-on experience is exactly what companies need. Let's show them you understand the full lifecycle of prompt engineering—not just writing clever prompts.
Crafting a Standout Prompt Engineer Summary
Your summary is the first thing recruiters see. Here are examples that actually work for entry-level prompt engineers:

Common Mistakes Prompt Engineers Make
❌ Mistake
Only mentioning prompt writing, not engineering
✓ Fix
Show the full stack: integration, evaluation, monitoring, error handling. Engineering means systems thinking.
❌ Mistake
No reliability or safety mentions
✓ Fix
Production LLMs need fallbacks, content filtering, and monitoring. Show you think about these.
❌ Mistake
Ignoring cost optimization
✓ Fix
Token costs add up. Mention any work on efficient prompting or API cost reduction.
Quick Wins
- Add production metrics: accuracy, latency, user satisfaction
- Mention evaluation frameworks and testing approaches
- Include cost optimization work—companies care about this
- Reference safety practices: input validation, output filtering
Frequently Asked Questions
How do I transition from personal projects to production?
Focus on reliability: error handling, fallbacks, monitoring. Show you think about edge cases and failures, not just happy paths.
Is LangChain experience important?
Increasingly yes. Orchestration frameworks show you can build complex LLM applications, not just single-prompt solutions.
Should I learn fine-tuning or focus on prompting?
Both are valuable. Start with prompting excellence, then add fine-tuning knowledge. Many production systems use both.
How important is understanding the underlying ML?
Helpful but not required. Understanding how LLMs work improves your prompting, but you can be effective without deep ML knowledge.
