About

As a Staff Software Engineer at Verve (AdTech), I architect and scale real-time data and targeting systems powering global advertising intelligence. My focus lies in building high-throughput, low-latency data platforms that process billions of events daily across distributed systems — leveraging Go, ScyllaDB, BigQuery, and Kubernetes. Previously, as CTO and Co-founder at Unmarshal, I led the development of a production-grade blockchain data indexing platform supporting 35+ chains and handling 100M+ daily transactions. Our systems powered enterprise-grade ETL pipelines, real-time APIs, and analytics infrastructure across multiple databases and data lakes. I thrive at the intersection of data engineering, systems architecture, and distributed platform design, blending my startup experience with deep technical execution. My background in scaling both AdTech and blockchain ecosystems reflects a consistent drive for reliability, performance, and elegant engineering at scale.
