A 22 percent increase in signal throughput for an autonomous warehouse robot prototype occurred after I reconfigured the phased array antenna element spacing during my senior capstone project. This challenge required me to perform extensive propagation modeling in MATLAB to overcome multipath interference issues within a high density industrial environment. As a Communications Systems Engineer candidate at Velocity Industrial Solutions, I bring a solid foundation in link budget analysis and spectral efficiency that directly addresses the connectivity needs of automated manufacturing fleets. My focus remains on delivering reliable high bandwidth links for complex robotic systems.

During my tenure as a lead hardware volunteer for a community broadband initiative, I optimized network latency by 15 percent by auditing local Wi-Fi channel allocation across twenty residential sectors using spectrum analysis tools. I later developed a Python based script that automated link budget calculations, reducing design verification time by 40 hours during my university research assistantship. Additionally, I successfully modeled 5G signal attenuation through various industrial materials by leveraging ADS simulation software. These technical efforts consistently focused on empirical validation to ensure robust signal integrity across diverse operating environments and hardware configurations.
