Graduated from UT Dallas, I’m a software developer building practical applications, exploring modern technologies, and creating useful tools that solve real-world problems.
I’m Mark Armstrong, a Computer Science graduate from The University of Texas at Dallas passionate about building impactful software and solving real-world problems. I have experience with full-stack development and machine learning, with knowledge of Python, JavaScript, SQL, Blue Prism, SharePoint, and AWS Cloud Computing. Through my internships and projects, I’ve gained hands-on experience solving technical challenges and working with different technologies. I enjoy learning, building meaningful solutions, and continuously growing my skills.
Outside of coding, I enjoy fishing, cooking, and weightlifting. I’ve been weightlifting for the past four years and enjoy documenting my progress through vlogs and videos. I also enjoy spending time outdoors and experimenting with new recipes. These hobbies keep me active, creative, and balanced.
