Software Engineer & Full Stack Developer | Ruben Christopher Arevalo
A software engineer who loves to learn, create, and implement ambitious and scalable full stack solutions for users and businesses across the Rio Grande Valley.
About Me
My name is Ruben Arevalo, and I am a software engineer and full stack developer from McAllen, Texas.
I wrote my first line of code in 2017 while I pursued an associate's degree in computer science during my junior year of high school. For the past 8 years, I have learned a lot of lessons along the way, and have taken a keen interest in software development as a result of my experiences.
My interest in software development also extends into integrating generative AI into products to help improve and streamline processes, such as incorporating RAG pipelines to provide more accurate responses by using an external source for reference (e.g. company policies, a database of research articles about best software engineering practices, etc).
I strive to improve and learn new lessons every day, as well as continuously hone my craft in programming so that I can apply what I learned into finding solutions for real-world problems prevalent in today's society, both current and new.
