01 / About
Data infrastructure at scale
At Datadog, I work on large-scale billing data pipelines and the infrastructure behind their scheduling, computation, storage, and reliability.
My work sits at the intersection of workflow orchestration, distributed systems, lakehouse architecture, and stream processing. I care about systems that are dependable in production and understandable by the people who operate them.
Beyond code, I invest in contributor experience: thoughtful reviews, clear documentation, and maintainable foundations that help teams and communities move faster.
