    I have a BS, MS, and PhD in Computer Science from North American universities, specializing in data analytics, data mining, and general database concepts. I have ten years of relevant work experience, ranging from building computer simulations of missile systems to authoring financial reports. I have a wide range of skills in statistical analysis (e.g., prediction, classification, modeling), software development (e.g., version control, bug tracking, integration, debugging), and text mining (e.g., natural language processing as well as more advanced techniques). I have applied these skills in both academic and industrial situations. I have statistical analysis experience with R, MATLAB, Excel, and SPSS. I am fluent in C/C++, Java, Perl, and Python. I have worked with many DBMS systems, including SQL Server, PostgreSQL, and MongoDB. I am willing and able to learn new languages and processes. I have excellent documentation and technical writing skills. I have more than 10 publications (which have a cumulative of 80+ citations) in international conferences and journals. In addition, in my past positions I have authored user manuals and developer guidelines for a range of software products and algorithms. I maintain a technical blog. Above all, I am an effective communicator, hard worker, and self starter.  less
