As a highly skilled and experienced full stack software engineer, I specialize in architecture design, web development, and real-time applications. With a unique collection of abilities across the stack, I have successfully developed and architected systems from the ground up, handling potentially petabytes of data and billions of rows of sensor data. My expertise includes proficiency in languages such as React, TypeScript, C/C++, C#, Python, .NET, Java, VHDL, Python, Assembly, HTML/CSS, and JVM.I currently work as a Software Engineer for a prototyping group, where I am responsible for developing a system from the ground up to handle potentially petabytes of data and billions of rows of sensor data from a set of different UUVs with changing values. I am proficient in agile methodologies, using tools such as OpenProject, Jira, GitHub, and GitLab to facilitate development. I possess strong team-building and leadership skills, and have experience mentoring new developers and helping to lead projects.I am also experienced in modeling and simulation using ROS, and have experience with development and configuration of PetaLinux/Yocto, VHDL, Vivado, FPGAs, and CPLDs. I have also helped to conform software to 510(k) FDA clearance requirements.I am a graduate of Virginia Commonwealth University, where I earned my Bachelor of Science in Computer Engineering, and also have an Associate’s degree in Pre-Engineering from Rappahannock Community College. Additionally, I have an active secret clearance.I am always looking to expand my knowledge and skills, and have developed my own portfolio website hosted on AWS using Angular and TypeScript.
