Mechanical engineer with 4 years of R&D and NPD experience across automotive radar (ADAS) and 5G antenna systems. I work at the intersection of design, simulation, and manufacturing — taking products from concept to production-ready hardware.
My toolkit spans FEA/CFD simulation, DFM/DFA-driven design, injection molding, sheet metal, and FDM prototyping. I'm particularly passionate about using simulation to reduce physical iteration cycles and finding clever mechanical solutions to tricky product constraints.
