Professional Achievements • Reverse engineered Symantec Ghost (hard drive backup) file format while learning IDA Pro and digital forensics, and wrote the code in less than two weeks. • Took leadership of doomed to fail project, where a text recognition module developed by a team of 6 people over 4 years was not reliable enough, and developed new system with OCR engine and image recognition module using new algorithm that bested FFT, all in under two months. • Redesigned closed captioning module for setup box, avoiding memory allocation and fragmentation that was making it slow. • Took leadership of doomed to fail project, where we were missing the most important source code. Architected and design the new system to replace the old one developed by 5 programmers over 4 years. New cloud system had significant improvements and more features, was much faster, had security module, and the source code was about 10% of the old system (accounting only the provided code, not the missing one.) Front end was a single page web app with sub-zero response, average 30ms. The project took about 7 months to develop, deploy and go live. • Implemented a process optimization to improve speed from about 2 hours to 11 minutes. A three prong approach: ◦ Arrange switch statement to process most common data first. ◦ Reverse engineer library code to deduce invariant data in the calculation of geo spatial data and reuse the invariant always and only calculate the rest. ◦ Import database process was optimized to use file based import and multithreading.
