Gig Summary
About this gig
Most people don't have a prompt problem. They have a specification problem - they tell the model what to write instead of what "correct" looks like. So it works on Monday, drifts by Thursday, and nobody can say why.
I write the spec first, then test it until it holds.
WHAT YOU GET
- The prompt, copy-paste ready, with variables marked so your team can reuse it
- A system prompt if you're building an assistant, custom GPT or automation
- Usage notes: which model, what to change, what good output looks like
- The edge cases I tested it against, and what it did
- Free retuning if it drifts within 14 days
WORKS WITH
ChatGPT (GPT-4 / GPT-5), Claude, Gemini, Grok, Llama - and prompts built for n8n, Make, custom GPTs or in-app assistants.
TYPICAL JOBS
Support replies that stay on policy. Content that stays on brand. Data extraction that returns the same format every time. Agent instructions that stop looping.
Send me one output you'd call correct and one you'd call wrong. That's usually all I need to start.

FAQ
What is prompt engineering, and how will it help me?
Prompt engineering is the process of designing and testing instructions so AI models like ChatGPT, Claude, and Gemini return accurate, consistent results. Strong prompts save you time and give you reliable output you can reuse, instead of re-explaining your task every time.
What do you need from me to start?
A short brief: your goal, the AI model or tool you use, and one or two examples of the output you want. The clearer your brief, the faster and better your result.
Which AI models do you support?
ChatGPT (GPT-4 and GPT-5), Claude, Gemini, Grok, Llama and most major LLMs. If you use a specific tool — n8n, Make, a custom GPT, or an in-app assistant — tell me and I'll tailor the prompts to that environment.
Which AI models do you support?
ChatGPT (including GPT-4 and GPT-5), Claude, Gemini, and most major LLMs. If you use a specific tool or platform, mention it and I'll tailor the prompts to it.
Do you offer revisions?
Yes. Every package includes revisions so we can fine-tune the wording and output until it performs the way you need.
Do you build full chatbots or apps?
This gig focuses on prompt engineering and optimization, not full chatbot coding or app development. If you need prompts for a chatbot or assistant, that's exactly what I do, so message me and I'll scope it.
