Scientific and custom programming

Ukraine - Last active: 20 days ago - Tests: 16

Over the last 12 years I have developed a range of scientific and custom applications, among which are weather-predicting and water modeling systems, visualization with Qt4 and OpenGL, parallel programming with MPI. I am proficient in Linux, Fortran, shell programming, AWK, C, and C++. I have a hands-on experience with MySQL, Apache, Python and Java. My current interests include Nvidia CUDA, Common Lisp, Clojure Lisp, and signal processing. Hmmm... No market for MPI and Fortran, you say? All right, here is my shiny recent skill: Objective-C, Mac OS X, iPhone OS.
