@ UT Dallas, graduating in 2026, 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 senior at The University of Texas at Dallas majoring in Computer Science. I love building impactful software, exploring new technologies, and solving real-world problems. I’m currently seeking software development opportunities where I can contribute to meaningful projects and grow my technical skills. Outside of coding, I enjoy fishing, cooking, and weightlifting — staying balanced fuels my creativity and problem-solving.
I have experience building full-stack web applications, machine learning models, and interactive games, working with technologies like Python, JavaScript, PHP, C#, and SQL. I enjoy solving both frontend and backend challenges, integrating APIs, optimizing performance, and creating smooth user experiences.
