## Summary

Hardik Kabaria, Director of Software Engineering at Carbon, explains how his team developed a 3D-printed COVID-19 test swab using lattice structures to address supply chain shortages. He details the mechanics of lattice design, comparing it to biomimicry and traditional manufacturing, and discusses the computational geometry and linear algebra algorithms that power Carbon's design engine. Kabaria also shares insights on his career path from mechanical engineering to software, emphasizing the importance of solving interesting problems over focusing on specific skills.
