I’m a Software Developer and Engineer with over 3 years of professional experience and a strong academic foundation from The Ohio State University (BS, Computer Science & Engineering).

I specialize in building maintainable, high-availability software across the full stack — from web and mobile applications to cloud infrastructure, real-time systems, and game development. I enjoy solving complex problems, designing clean architectures, and delivering production-ready solutions that have real-world impact.

Currently, I’m working at RMR Development, where I design, build, and maintain software systems used by hundreds of thousands of users across multiple industries.
