About

Data Engineer with six years of experience deploying and analyzing market data. Strong track record of data accuracy and deploying data metics. My studies as a Master of science candidate in Mathematics from Arkansas State University have rounded out this experience. This program looks like out offered real-world, but it never leaves the real-world. I can combine the knowledge I have learned from the master with what I have learned in bachelor and come out better results. Interested in an entry-level position in data analysis or data scientist. Also qualified and experienced with teaching college algebra; extensive volunteer service in classrooms and after-school programs.
