About Me

My Experience

Software Development

I developed countless Amazon Alexa skills in NodeJS and Amazon’s Alexa Skills Kit. I also developed an audio sharing web app for one of my company’s clients using the Python Flask library and popular cloud technologies. Most recently, I developed a customized survey application for a professor at Iowa State University in React and NodeJS. I have also had the opportunity to work as a software engineering intern at a large company where I originally developed tests in JMeter, Selenium, and Gauge. I also performed software maintenance where I resolved defects, assisted with tier three support tickets, and fixed security vulnerabilities.

Security

Security is paramount to any project that I am working on. From ensuring proper firewall rules on a network install to preventing SQL injection on a web application, I have learned being diligent about security is always crucial. I realized this importance and chose to pursue cybersecurity as a minor when in college. I have previously worked as a penetration testing intern where I conducted for internal, external, and physical tests at major companies. I currently work as a cyber security consultant at my full-time job.

Network Administration

A simple quest to extend WiFi to my grandma’s garden patio has led to one of my focuses. It started with learning about multiple access points and routing basics and soon terms like VPN, VLAN, and SD-WAN did not seem so foreign. My company has previously done large scale network deployments in RV parks, schools, churches, and a shopping mall. I take pride in my work and strive to have tidy installations. While I may not use my network administration skills daily in a full-time job, they are helpful to know and are a great way to help small businesses in the community.

Project Management

Through the projects I have worked on, I have realized that my technical skills can turn out futile without adequate project management. My projects have often involved coordinating with subcontractors, vendors, and the client. Keeping these parties in sync has required me to become a better project manager and develop stronger communication skills. In school, I feel most engaged in class projects where I am able to empower others to communicate their ideas and stay on schedule. I further fortified these skills with my Master of Business Administration I received at Iowa State University.
