About Me

Hello! I'm Ryan Medeiros, a passionate Computer Science graduate from UMass Dartmouth with a specialized concentration in Cybersecurity. Growing up as a Portuguese American in the Fall River, MA area, I'm proud to be a first-generation college graduate and I'm fluent in both Portuguese and English.
My journey into technology began at Diman Regional Vocational Technical High School, where I graduated from the Programming and Web Development program. This early exposure to coding sparked my passion for computer science and set me on the path that led to earning my Bachelor's degree from UMass Dartmouth.
When I'm not coding or working, you'll find me pursuing my other passions. I'm an avid PC gamer and enjoy building custom computers, working on cars, hiking and exploring new places, working with Legos, and diving into new coding projects just for fun. My diverse interests have taught me to approach problems from multiple angles, whether I'm debugging code, troubleshooting a car engine, or planning the perfect PC build.
