Reviewer for the American Mathematical Society

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 but not limited to 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 where my thesis was published at the Journal of Mathematical Cryptology and ranked with the highest grade among the master theses of the corresponding semester at the mathematics department .

I am fluent in Spanish, English and Turkish. I have an intermediate level in German.
