What I'm looking for

I seek senior engineering roles focused on cloud-native, scalable systems where I can lead platform modernization, reduce costs, and mentor teams in a collaborative, outcome-driven environment.

I am a software engineer with 5+ years building scalable distributed systems across cloud environments (AWS, GCP) and modern full‑stack technologies. I focus on delivering measurable business impact, including cost savings and traffic growth for large consumer platforms.

At Expedia Group I architected high-volume publishing tools and distributed intelligence platforms, led legacy modernization with ClickHouse and Golang, and built AI-driven ad generation pipelines that improved performance and operational efficiency.

I enjoy designing cloud-native architectures, improving data pipelines, and collaborating with cross-functional teams to deliver production-grade solutions that scale and reduce costs.
