Based in San Antonio, TX, I specialize in the interception and analysis of coded foreign intelligence communications, leveraging advanced signal intelligence (SIGINT) equipment and methodologies. My expertise encompasses RF signal analysis, bitstream evaluation, and digital communication systems, enabling me to detect, classify, and document complex signals effectively.            /p>            p>                Throughout my military career, I have demonstrated a commitment to excellence and leadership. As a top graduate of the Advanced Signal Analysis (452) course, I achieved the highest GPA ever recorded for the program at 99.76%, while also serving as the class leader and contributing to a record class GPA of 97.4%. My training in this course has equipped me with advanced knowledge of modulation techniques, satellite communications, and network analysis, positioning me as a subject matter expert in fine-grain signal classification and demodulation. Similarly, during the Intermediate Signal Analysis (451) course, I earned a 99.72% GPA as the top graduate and class leader, reinforcing my technical expertise and leadership capabilities. In my role, I employ Linux and UNIX systems for efficient signal analysis and operational control, further solidifying my technical foundation.            /p>            p>                In addition to my military accomplishments, I hold a Bachelor of Science in Information Technology with an emphasis in Cybersecurity from Grand Canyon University, where I was a Deans List honoree. I am currently pursuing a Master of Science in Cybersecurity, with anticipated graduation in November 2025. My certifications, including the eJPT, Google Advanced Data Analytics, and Google IT Automation with Python, reflect my dedication to continuous professional development.            /p>            p>                My passion for cybersecurity extends beyond my formal education. I have developed innovative projects such as HashTag, a hash-cracking tool, and DrRobot, an encryption software. My technical repertoire spans programming in Python and C, AWS integration, Elasticsearch, MATLAB, and Linux system management. Notably, I constructed a virtual 8/16-bit CPU using Von Neumann Architecture and engineered custom networking protocols for secure data transmission. These projects demonstrate my problem-solving capabilities and commitment to advancing cybersecurity practices.            /p>            p>                In my extracurricular pursuits, I have contributed to diverse fields, from leading compositions in a video game development club to achieving recognition as an All-State Musician. My collaborative experiences have reinforced my belief in the importance of diversity, equity, and inclusion. Whether mentoring peers in Python programming or addressing unique challenges within my team, I strive to foster an environment that values diverse perspectives and talents.            /p>            p>                Diversity, equity, and inclusion are core values in my life and work. My varied experiences, from analyzing signals in the Army to engaging with the NSA, have taught me the strength that comes from diverse perspectives in tackling complex challenges. Whether leading a class in military training or teaching Python to military members, I strive to create an environment where different talents and backgrounds can thrive collectively. This commitment extends to my interactions, where I emphasize empathy and support, notably when I aided a fellow soldier in a personal crisis, highlighting the importance of understanding and addressing the unique challenges of those around us.            /p>            p>                As I continue my career, my focus remains on integrating my technical expertise with leadership skills to address complex challenges in signal intelligence and cybersecurity. My ultimate goal is to advance as a leader and innovator, contributing to the security and efficiency of critical operations while supporting and inspiring those I work alongside.            /p>        /section>        !-- Plan Section -->        section idplan>            h2>My Plan for the Future/h2>            ul>                li>                    strong>Technical Advancement:/strong>                    ul>                        li>Complete MCCEP Phase II for SAE (Signal Analysis ELINT) and SAC (Signal Analysis COMINT)./li>                    /ul>                /li>                li>                    strong>Certifications and Professional Development:/strong>                    ul>                        li>Take and pass the eCPPT - Late 2025/li>                        li>Pursue additional certifications such as CCNA, Net+, and AWS, depending on available funding./li>                    /ul>                /li>                li>                    strong>Career Progression:/strong>                    ul>                        li>Prepare for and attend my Promotion Board to advance to Sergeant./li>                        li>Put in a reclassification packet for 17C (Cyber Operations Specialist)./li>                    /ul>                /li>                li>                    strong>Educational Goals:/strong>                    ul>                        li>Continue my education with a Master of Science in Cybersecurity at Grand Canyon University./li>                    /ul>                /li>                li>                    strong>Financial Planning:/strong>                    ul>                        li>Max out my Roth IRA contributions for the year 2025./li>                    /ul>                /li>                li>                    strong>Networking and Mentorship:/strong>                    ul>                        li>Engage more actively in professional networks./li>                        li>Seek mentorship opportunities within the cybersecurity and military communities./li>                    /ul>                /li>                li>                    strong>Community Involvement:/strong>                    ul>                        li>Contribute to community outreach, especially in technology education for youth and military communities./li>                    /ul>                /li>                li>                    strong>Research Interests:/strong>                    ul>                        li>Explore specific areas of cybersecurity research during my Master’s program, focusing on advanced cryptography and signal modulation./li>                    /ul>                /li>            /ul>        /section>        section ideducation>            h2>Education/h2>            ul>                li>                    strong>Grand Canyon University/strong> (05/02/2022 - 06/09/2024)                    ul>                        li>Bachelors of Science in Information Technology with an Emphasis in Cybersecurity/li>                    /ul>                /li>                li>                    strong>Grand Canyon University/strong> (07/18/2024 - CURRENT)                    ul>                        li>Masters of Science in Cybersecurity/li>                        li>Expected graduation: 11/19/2025/li>                    /ul>                /li>                li>                    strong>Arizona State University/strong> (08/21/2020 - 12/10/2021)                    ul>                        li>Studied Aerospace Engineering and Mathematics/li>                    /ul>                /li>                li>                    strong>Maricopa Community College/strong> (08/15/2018 - 05/22/2020)                    ul>                        li>Completed General Studies coursework/li>                        li>Concurrent enrollment with Boulder Creek High School, Anthem, AZ/li>                    /ul>                /li>                li>                    strong>Advanced Signal Analysis/strong> (07/11/2024 - 11/06/2024)                    ul>                        li>Avg.
