About Christopher Marroquin
I am a Software Engineering and Digital Business student at ESEN focused on full-stack development, structured problem-solving, and building systems that create real value.
My technical foundation combines React, TypeScript, JavaScript, SQL, and backend systems with a strong execution mindset shaped by competitive programming and practical product work.
Beyond writing code, I build technical initiatives where software, operations, and community growth need to work together under real constraints.
That combination has led me to co-found C3, teach data structures and algorithms, support software development courses, and keep growing through real projects and hands-on work.
