What to look for in a OpenAI API freelancer
A strong OpenAI API developer builds around the model's limits, not just its best-case output. Look for:
- Real API experience, handling streaming, rate limits, retries, and errors cleanly.
- Grounding know-how, using retrieval and structured prompts to cut hallucinations.
- Solid backend skills, integrating the API safely into your app with keys kept secret.
- Cost awareness, managing tokens, caching, and model choice so spend stays sane.
- An eye for evaluation, testing output quality before it ships to users.
Ask how a candidate keeps API keys and costs under control in production. Anyone can call the API once, but handling it safely at scale is the real skill.
