Roger S.Private profile: Upwork shows its earnings only to signed-in members, so we check it every few weeks, not daily. MRR here is a rough estimate (Upwork's six-month earnings ÷ months active). Last read Nov 5, 2026.

I'm experienced in writing MATLAB scripts to model, simulate and control a wide variety of dynamical systems and create optimization routines. I'm also experienced with C++ and Python. One example of something I've done in C++ is using the open-source library PSOPT to solve an optimal ascent trajectory of a rocket launcher. In Python, I wrote a simple algorithm to count plants of images with the OpenCV library. I'm currently working on the simulation of satellite orbits, and the objective is to quantify how much error is inputted into the dynamical model by using a less accurate and decreasingly complex gravitational model. This project requires knowledge of C++, Python, and MATLAB.
