    With many years of experience in various IT companies I am ready to propose following services on "as-needed" basis (sorry, no fulltime employment): 1) Complex engineering tasks related to server-side linux scripts, such as troubleshooting, code review, implementation/adjustment of complicated logic. Supported languages: python, perl, ruby, bash, lua. Haskell, erlang, clojure are possible as well. They are subject of special (lower) rates, due to lack of practical experience (versus solid theoretical understanding and general interest). 2) Advisory in organisational questions for small & medium teams. Workflows, infrastructure, staffing, project management (including risks management, resources management, planning etc). 3) High-level design of the service-oriented architectures, data processing (ETL) flows, devops solutions in linux/cloud environments. 4) Any kind of engineering/architectural work related to functional programming, evented programming, nosql. 5) Advisory/troubleshooting on nginx and hadoop, with basic practical experience in high-load web services and massive data processing. Rates are flexible, depending on particular case. Is this expertise exactly fitting your problem? If so, just message me. Not sure? Message me anyway so we will find an answer together.  less

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
