I’m a Computer Science and Engineering graduate from The Ohio State University who enjoys building practical software—especially where strong front-end experiences meet reliable back-end functionality. I’ve worked on full-scale, SQL-based BI environments, web applications, and data/reporting workflows, and I’m comfortable collaborating with teams and communicating with stakeholders. In my recent roles and capstone experience, I’ve supported both legacy modernization and new development, using tools like React Native, Express/JavaScript, AWS, .NET, Angular, C#, Power BI (DAX), and SQL. I’m motivated by opportunities that blend software engineering, problem-solving, and continuous learning across software development and data-driven projects.…I’m a Computer Science and Engineering graduate from The Ohio State University who enjoys building practical software—especially where strong front-end experiences meet reliable back-end functionality.
