As the mechanical team lead, I coordinated the integration of mechanical components with electrical and software subsystems, ensuring interface compatibility and alignment across the full satellite. I oversaw tolerance analyses, structural layouts, and iterative prototyping to mitigate integration risk early in the design cycle, and I lead environmental testing efforts to validate mechanical and thermal performance under representative launch and on-orbit conditions. In addition, I supervised the development of detailed assembly and integration guides, defining assembly order, fastener specifications, handling procedures, and verification steps to ensure repeatable and reliable spacecraft builds. My role also included coordinating subsystem-level mechanical requirements, managing design reviews, and supporting system-level integration to ensure the CubeSat meets both functional and mission constraints.
