What I'm looking for

I’m looking for a role where I can develop spacecraft flight-dynamics and onboard/simulation software, combining applied celestial mechanics with data analysis and HPC. I want a team focused on reliable algorithms, clear technical documentation, and meaningful mission impact.

I’m a Research Engineer and Analyst specializing in Fundamental Mathematics and Mechanics. I work across applied mathematics, data analysis, space systems modeling, and spacecraft motion algorithm development.

Currently, I’m working at JSC Lavochkin Association in the Spacecraft Flight Dynamics department. I’ve refactored and updated an onboard software module for continuous roll angle scanning mode, and developed software for processing magnetometric test data and statistical processing for solar attitude determination and control modes.

I also focus heavily on onboard and simulation software development. I build cross-platform graphical user interfaces (GUIs) using Qt, develop modules for calculating and visualizing physical and magnetic fields, and mathematically validate attitude determination and control algorithms for a lunar remote sensing spacecraft using low-thrust RCS thrusters.

Earlier, I completed a research internship at the Keldysh Institute of Applied Mathematics (KIAM RAS). My work centered on halo orbit construction in the Earth–Moon system, including C++ (Qt) algorithm development with a full perturbation model, trajectory optimization, and orbital stability analysis.
