Developed and implemented novel algorithms for magnetohydrodynamics, which can reduce communication time by 75% (Hyperbolic conservation laws, finite difference WENO, plasma physics, C++, Mathematica). Wrote interfaces to external visualization softwares, enabling the team to analyze hundreds of gigabytes of data per simulation run (C++). Restructured build system of a project consisting of 100K lines and 160 targets, increasing build speed by more than 10x (CMake, C++, Python). Tuned performance-critical parts of various codes, increasing speed by up to 8x (C++). Wrote a parser for parameter files, reducing numerous ad hoc classes to a single configuration script (Ragel, Python, C++). Developed a set of web-based lecture notes for calculus classes, with very positive feedbacks from students (HTML5).
