About Alex Semaca

Structural analysis engineer with experience working across the aerospace industry, primarily on spacecraft and airframe structures, as well as rocket and jet engines. Skilled in finite element analysis (FEA) and classical hand calculations for metallic and composite components, and applying engineering judgment to determine the appropriate level of analysis for a given problem. Demonstrated history of delivering results with high productivity, as well as improving team efficiency by developing standard analysis tools and templates to automate common tasks and processes. Experience programming primarily in Matlab as well as Python, and proponent for using Git version control for analysis tools as well as finite element models.
