What I'm looking for

I seek senior engineering roles building scalable, tested data platforms and ML/analytics pipelines in cross-functional teams, with strong CI/CD and observability practices.

I am a Senior Data Engineer with 8+ years building scalable, reliable, high-performance data platforms across social media, creator economy, and e‑commerce domains. I specialize in designing real-time and batch pipelines and optimizing data infrastructure for latency, cost, and quality.

At organizations including Discord and Meta, I implemented pipelines and data models using Apache Spark, Databricks, Snowflake, Airflow, Kafka, and dbt, reducing dashboard latency, lowering compute costs, and improving dataset reliability and observability. I partner with data scientists, analysts, and product teams to enable experimentation, analytics, and ML workflows that drive product decisions.

I care about instrumentation, testability, and operational excellence—building modular ETL, observability, and CI/CD practices that scale across cloud ecosystems (AWS, GCP, Azure) and support rapid iteration and trustworthy insights.
