Meet the Exelaration Team Members

Featured Alumni

Katheryn Rizek, Class of ’20

Katheryn studied Industrial and Systems Engineering at Virginia Tech. Here, she learned the importance of process improvement, which she could then apply to Agile principles when joining Exelaration. Katheryn joined Exelaration the summer after her sophomore year and stayed through graduation. She learned much about full-stack software development and Agile methodologies and got to work on projects with private companies, the federal government, and non-profits. The projects utilized technologies ranging from JavaScript, Java, Ruby, and Python. Today, Katheryn is a Senior Consultant with Excella where she is supporting the Consumer Financial Protection Bureau with their software for responding to consumer complaints about financial institutions.


“Exelaration opened me up to a career in software development that I never thought I could achieve. I had previously taken a computer science class in college with hundreds of other students and finished the course thinking a career in tech was not for me. Through a friend, I found the XC and quickly and passionately learned key software development principles through their supportive, hands-on teaching style.”


Dan Nguyen, Class of ’20

Dan studied Industrial and Systems Engineering at Virginia Tech, a field that helped him develop both technical and soft skills in numerous areas. Even though academic obligations and campus involvements kept him busy, Dan went above and beyond in order to pursue new challenges and experiences. For the latter half of his undergraduate career, Dan joined Exelaration where he began an adventure in the world of full-stack software development and Agile methodologies. Today, Dan is a GPS Analyst at Deloitte, where he applies all of his past experiences to make lasting contributions to the firm, putting his technical and soft skills to use.


“The XC exposed me to a lot of different languages, frameworks, and technology. It helped me to become more confident in my technical abilities.”
