Prompt Engineer Needed to Clean & Finalize Existing Prompts

I already have all prompts written for my study app (Mentura.ai).
I just need a Prompt Engineer to:
• Review the existing prompts (they are already organized)
• Clean them up for clarity and consistency
• Make sure they produce stable outputs
• Define the final JSON response formats
• Provide a few sample JSON outputs for each mode
(exam, quiz, study, review — all prompts already exist)

No heavy writing, no complex creation — just tuning + testing what is already there.
