Gurumanie Singh Dhiman | Portfolio
Hi! I'm a concurrent Cybersecurity and Computer Engineering student at Iowa State University – pursuing my B.S. in Computer Engineering (Class of 2026). My academic and professional journey centers on building secure, scalable networked systems through hands-on research, applied cybersecurity projects, and advanced coursework in information assurance and network defense.
Actively seeking opportunities to apply my expertise in network security, cybersecurity operations, and secure system design.
Administered a multi-node wireless network across Ames, IA, ensuring stable connectivity for critical user equipment while troubleshooting system-level failures using journalctl and network diagnostic tools. I deployed configuration updates to base stations and user equipment through Docker containerization, Systemd service orchestration, and flco-cli automation, which enhanced throughput, reliability, and interference mitigation. Additionally, I authored comprehensive technical documentation with Sphinx and reStructuredText, streamlining deployment procedures and reducing onboarding time for new team members. Throughout the project, I collaborated closely with research staff and engineers to align network modifications with evolving project requirements.
Worked as a Supplemental Instruction Leader for Data Structures & Algorithms, hosting three after-class sessions weekly with an average of 13 students per session to prepare them for tests and quizzes. Additionally, I led 2-hour review sessions before midterms and final exams, attended by over 100 students. These efforts collectively led to a 30% average improvement in student scores compared to non-attendees.
Completed National Service in the Singapore Armed Forces (SAF), where I securely managed close to 500+ personnel files, including physical fitness scores and medical information. I meticulously tracked these scores for annual inter-battalion competitions, demonstrating strong data integrity and organizational skills.
Analyzed offensive and defensive cyber operations, including threat intelligence, nation-state tactics, propaganda campaigns, and strategic approaches to protecting critical infrastructure.
