Summary

Mathematics student and aspiring pilot with a strong foundation in technical problem-solving and precision. My professional background is rooted in the outdoor industry, bringing hands-on expertise in hardgoods sales, custom boot fitting, and bicycle mechanics. As an active alpinist, trad climber, and freeride splitboarder, I bridge the gap between technical equipment specs and real-world performance. Whether I am working through a complex mathematical proof, preparing for flight training, or servicing gear, I am driven by a highly analytical, detail-oriented, and hands-on approach.
