Summary
👤
Senior🎓
Top SchoolPetr Stepanov is an application specialist and software developer with 10 years of experience blending nuclear physics research and full-stack engineering, currently based in Portland, Oregon. He holds a Ph.D. in Photochemical Sciences and has applied C++ ROOT and Geant4 at national labs to analyze hundreds of gigabytes of experimental data and accelerate simulations on HPC clusters. Equally comfortable in UI/UX and front-end stacks, he has shipped performant static sites, iOS apps, and frontend systems that improved page speed and SEO measurably. An active contributor to the widely used ROOT project—enhancing TMVA data handling and robust fitting—he brings a rare combination of deep scientific instrumentation knowledge and practical software craftsmanship. Open to industry development roles or computational science positions at national labs, he pairs research rigor with production-focused engineering and a designer’s eye.
