About Me

Hi, my name is Ever Barillas, a Software Engineer with a passion for building scalable, efficient, and data-driven solutions. My last position was at Microsoft, where I contributed to Azure Cost Management, optimizing cloud financial operations through automation and intelligent engineering.

I hold a B.S. in Computer Science from Pennsylvania State University and have experience across the full software development stack, from front-end interfaces to back-end systems, leveraging modern frameworks and cloud technologies. Rather than sticking to a single programming language, I focus on selecting the most effective tool for each task, ensuring optimal performance and scalability.

Beyond my professional work, I enjoy exploring personal projects that allow me to experiment with innovative mobile and web technologies while enhancing user experiences. Solving intricate problems in app and web development continues to be a rewarding pursuit in my spare time.
