About Me

I'm Cesar Villarreal, a software engineer and cloud professional with a Master's degree in Software Engineering from Kennesaw State University, maintaining a 3.8 GPA. My career combines hands-on technical expertise with a passion for education and knowledge sharing.

As a game design, computer science, and robotics teacher, I develop and deliver comprehensive curriculum for aspiring engineers and mentor students as they build their first games, programs, and robots. Alongside teaching, I designed and built STEM Quest, a production-deployed learning management system — solo-built with React, Django, and PostgreSQL, and running entirely on free-tier cloud infrastructure. The platform streamlines course delivery, mastery-based quizzes, and student progress tracking while reflecting modern development practices end to end.

Prior to education, I served as a Cloud Engineer at Cognizant Technical Solutions, where I supported enterprise infrastructure engagements and earned my AWS Solutions Architect Associate certification. This experience provided deep expertise in cloud architecture, infrastructure automation, and scalable system design.

My technical focus spans enterprise application development with Spring Boot and .NET Core, cloud infrastructure on AWS, and full-stack web development. I excel at translating complex technical requirements into elegant, maintainable solutions and explaining sophisticated concepts in accessible terms.
