Hey, my name is Roen.

  • 📚 I’m studying computer science at ASU
  • 🌴 From Kailua, Hawaii
  • 💪 In my free time, I enjoy lifting, the beach, and spending time with my friends & family.

I’m studying Computer Science with a minor in Engineering Management at ASU to pursue a career in cybersecurity. I develop some free and open source software (FOSS), as well as some proprietary software on the side.


Building Silent Activation and Improved Location Accuracy Into the Current 911 System

Engineered and presented a novel method to contact emergency services if victim is under duress or otherwise unable to talk on the phone. Especially useful in situations such as kidnappings, domestic violence, etc. Project presented at ISEF 2022 in Atlanta, GA and received $5000 award from Oracle Academy for outstanding project in Systems Software. Full abstract available here.

Skills: Swift, MySQL, PHP, System Integration, Linux, and Public Speaking

Worldwide Coronavirus Statistics

In the midst of the COVID pandemic, I wrote a live-updating global coronavirus tracker website at https://covid-019.com. This backend data processing is written using Python using the pandas library, which normalizes data from different sources into CSV files for different regions. It also decides which data source should be treated as authoritative for each region. NodeJS ingests the CSV files that the Python script outputs and converts them into nice looking graphs using HTML, CSS, and JS. Graphs are generated using the d3.js library. At its peak, the website garnered over 500 unique visitors per day. This presented code efficiency and reliability issues, which I was able to solve by leveraging the nginx web server to cache pages for a short period. Computing resources for this project were generously donated by DigitalOcean.

I also work as a freelance sysadmin and web designer for some small businesses in my hometown of Kailua, HI. Some work samples are listed below.
