Maciej Pulikowski - founder JsonGPT API

Hey, it's Maciej πŸ‘‹

I am πŸ§™ Software Engineer and πŸ‘Ύ Security Researcher ( πŸ† 8 x Listed in Google's Hall of Fame)

I realized that generating JSONs from LLMs should be easy and perfect, but it is NOT. That's why I built JsonGPT API.

JsonGPT API makes it incredibly easy to get the AI-generated JSON data you need. I built it because:

  • Save time ⏳ - One simple endpoint to get AI data for new project, making everything work seamlessly without a lot of code
  • Avoid headaches πŸ€• - Parsing generated JSON from LLMs is not simple. I invested significant time to perfect it
  • Grow quickly πŸš€ - The more you build, the more you learn, the more you earn

Now, I can spend less time on repetitive tasks and focus on what truly matters - building my business. Join me on this journey 😊
