Experience
Software Engineering Co-op
DataPath, Inc.
May 2023 - Current


At DataPath, I lead an internal effort to improve the security posture of DataPath’s Q-Series portable satellite dishes as well as network management software, MaxView. It has been an incredible opportunity to make an impact on the direction of the company!
  • Spearheaded effort to overhaul Q-Series satellite dish software architecture to satisfy security requirements for multi-million dollar contracts
  • Designed and executed a penetration testing framework tailored to DataPath’s network management software
  • Transformed software development team’s security posture and priorities, leading to over 20 critical vulnerabilities being resolved in months
  • Optimized testing/building processes by 90%, reducing development cycle time and improving code quality
  • Scripted internal security tools for client MaxView installs using Powershell and Python
Experience
Security Analyst
Georgia Tech Cybersecurity - Security Operations Center
August - December 2022


As a security analyst for Georgia Tech, I defended the security of Georgia Tech's workstations and servers from malicious executables and suspicious administrative actions. Every incident was an opportunity to learn new aspects and vulnerabilities of cyberspace.
  • Resolved hundreds of potentially malicious security incidents and suspicious activities, improving the security of Georgia Tech’s networks
  • Collaborated with coworkers to reach a verdict regarding incidents
  • Reasoned with minimal information to detect malicious activity on GT workstations
  • Documented security incidents in detail to streamline future incident responses
Experience
Network Hardware Support Student Assistant
Georgia Tech Network Services
March - August 2022


As a network hardware support student assistant, I configured the numerous Cisco network switches on Georgia Tech's campus. At Network Services, I had the chance to dip my toes in other fields, including with the Network Hardware Platform Transition project, in which I managed large data to create the "source of truth" for network access points on campus!
  • Lead effort to transition device management platform, significantly improving network incident response
  • Supported 10000+ network devices in 250+ buildings on Georgia Tech’s campus
  • Developed internal automation tools, reducing project time by over 80%
  • Upgraded existing network equipment to improve network latency to multi-gigabit speeds
  • Improved network device installation processes to reduce network downtime during upgrades
Project
WildTrack Wildlife Tracker Wiki
Client: Wildlife Movement Institute


During my final semester at Georgia Tech, I've had the privilege of working with the Wildlife Movement Institute on an effort to make wildlife tracker information accessible to all. Not only is this information usually behind paywalls (which WildTrack does not have), the WildTrack wiki allows experts to share their personal experiences with their work, a valuable resource for newer researchers.
  • From-scratch free and open-source web app allowing wildlife experts to share their specialized knowledge
  • Collaborated with five other engineers using agile methodology to deliver an enterprise product in four months
  • Utilized React and MongoDB to deliver a responsive and modern full-stack web application
  • Designed and built modern user interfaces and user experiences using Figma and Material Design guidelines
Project
Internal Software Vulnerability Assessment
DataPath, Inc.


To comply with federal and client requirements around cybersecurity vulnerabilities, I designed and executed a unique penetration testing framework according to DataPath's needs, which resulted in an improved security posture for our multi-million dollar contracts.
  • Created a unique penetration testing framework tailored to DataPath’s software and needs
  • Penetration tested MaxView using tools including Nessus, Metasploit, and Burpsuite
  • Discovered and documented over 20 major vulnerabilities
  • Initiated (and later executed) effort to remediate discovered security vulnerabilities
