Lottery Machine Control Software

I was responsible for this whole project using Qt to replace the old software developed using Flash by another department.

Later on, I was responsible for maintenance and being the contact person for the Philippines staff since I was the only one in the department who could communicate with them fluently.

Auto Receipt Checker System

• Disclaimer:

I will try to describe it here as vague as possible since I do not want to leave much text record of this highly sensitive project, although this is the most interesting one I participated in. We can discuss this project in the interview if you are interested in the details.

• Product/System Description:

The system will spider back the records of the clients' remittances.

• Contribution:

I was responsible for mainly two parts of the project: Windows API Hooking and Captcha (image) processing.

For the Windows API Hooking part, I successfully located the exact WinAPI(s) and later made the "Spoofing" trick.

For the second part, Captcha processing, I used C++ and OpenCV to process the Captcha image, rapidly raising the OCR service's correction rate. (from almost 0% to 70%)
