Perseverance  Dear prospective employer: Are you looking for someone off the script and persevering?  I have the ability to come up with new ideas. My first programming quiz at high school hinted to me what was going to be my passion.  Our class was given100 records, each with 3 numbers a , b and c . We were to identify which records correspond to a Pythagorean Triangle .  The straightforward solution that most students  proposed were the same: If      a 2 = b 2 + c 2   or   b 2 = a 2 + c 2    or    c 2 = b 2 + a 2    then the record corresponds to a  right triangle, but my approach to solve that quiz was different. Although I had no knowledge at all about algorithms I came up with a different solution.  I used Heron’s formula that is less time consuming and much more efficient. No one had seen this formula before. A week after grades were awarded the professor informed the students of the solution that had most impressed him.  One that was different from all proposed. It was

About ExSan

About ExSan ExSan is essentially a worksheet tool built on a novel data structure fully coded in C++, it is conceived using Object Oriented Technology. ExSan is console-oriented capable of handling large matrices, i t is used for a variety of applications for instance in Data Mining, Image Processing, Text Mining, Pattern Recognition, Artificial Intelligence, Financial Derivatives Pricing, Blockchain, Digital Forensics: Audio, Image & Video, Quant Finance (Quantitative analysis, High Frequency Trading and Low Latency Trading) and more general Numerical Computing ExSan application in Quant Finance It is much more easier to analyze data market in an environment dynamically declared. Market is basically stochastic, any code should be flexible and capable to adapt to the dynamics and eventualities. ExSan does full dynamic memory allocation. It is suitable to study any scenario of the data market. Code with variables declared as static should be avoided in Quant Finance
