Python, Java Programmer - Software Development Freelancer - Algorithm Expert, Researcher

I am a programmer/researcher/analyst who has both development and research experience in various fields such as cryptology/information security, application development, genomic data analysis, machine learning statistics. I have a deep understanding of algorithms and I also have very good knowledge on programming especially Java and Python. Regarding software development, through my entire career, I developed many different applications using Java and Python which includes software for managing printers, keyword extraction, statistical analysis, managing/populating and querying databases, java swing applications, social network analysis using Hadoop and MapReduce framework, applied machine learning with R, software testing, REST API development with Python. As a researcher in information security, I already have a patent, a conference proceeding and a journal publication. As a researcher in genetics, a hypothesis testing method for detecting genetic interactions. As a researcher in algorithms, an improved version of polynomial factorization. Finally, I have a completed draft on mathematical language processing where I use Bayesian networks. I have a master's degree in mathematics. I am fluent in Spanish, English and Turkish. I have an intermediate level in German.
