Car diagnostics for everyone

Hi! I'm the founder and creator of the original OBD Auto Doctor software. I once had issues with my car and wanted to know more about them. I did my research and found out about this system called On-board Diagnostics. It's a computer system that all modern cars have. It provides valuable information about the health and conditions of the car.

At that time, there wasn't any affordable and easy to use solutions available for people like me. I mean people like car enthusiasts or do-it-yourself mechanics. I became so fascinated about the OBD2 system that I wanted to learn it fully and build a tool myself. I wanted to share my knowledge and help everyone to know their cars better.

Today, I'm still part of the core team. You might even get email response from me to your support request. I take part in the daily activities to find out your needs and to keep the business on track. I really enjoy working with this tech and share my expertise and the tool with you!
