Data Engineer

Engineering Scalable Data Intelligence.

I build the engines that turn raw data into decisions. Specializing in scalable pipelines and distributed systems, I bridge the gap between engineering complexity and business value. My focus is simple: reliable architecture, high data quality, and shipping production-grade code.
