I’m a Computer Science sophomore at the University of Wisconsin–Madison. My interests center on database internals, distributed systems, and hardware-level performance optimization. I focus on engineering scalable backend infrastructure, ranging from columnar execution engines to fault-tolerant data pipelines.
