A software engineer, game creator, and CS student @ UT Austin 🤘

About Me

Aiden Johnson
Aiden Johnson

Hey there! I'm Aiden, a sophomore at The University of Texas at Austin majoring in Computer Science. I'm passionate about creating impactful software and saving lives through firefighting/paramedicine. When I'm not coding, I'm playing football (won intramurals Fall 2024!), going to the gym, or learning about firefighting and EMS.


Alongside my career in Computer Science, I plan to be a firefighter/paramedic. Ever since I was a kid, I've always had a strong desire to join the fire service and help people in their worst moments. Having both a career in the CS field while serving as a firefighter paramedic is my lifelong dream! I've actually made a game about first responding on Roblox, scroll down for more info!

Real-time Austin Fire Department incidents with unit tracking using Broadcastify and OpenAI APIs.
