    Software Engineer

    Russia - Tests: 6

    I've been programming different kinds of software systems since 1999, using the following technologies: Python, C, C++, awk, bash, sed, Perl, Forth, Clipper, Harbour, PHP, SAS/Base, SAS/Macro, Java, JavaScript, Tcl, PostgreSQL, HTML, CSS, Oracle, MongoDB, Django, Celery, and numerous others. In the past, I worked on NLP software, developing a DBMS for linguistic research. Furthermore, I developed various Web portals with responsibilities ranging from consulting and modeling to integration, optimization, and long-term support. Also, I have huge experience in Big Data, including data warehousing, ETL and statistical analysis. My skills also include OS distribution optimization and embedded microprocessor programming. In my work, I am a perfectionist who, at the same time, cares about developing a solution which will be both simple and doing its job well. I learn new technologies quickly and I work with legacy code easily. Performance optimization and data modeling are my favourite fields of work.
