Andrew andy

I am a Senior Data Engineer with a strong track record designing, building, and scaling ETL/ELT pipelines across enterprise analytics, high-volume marketplace systems, and robotics ML training. I bring deep expertise in SQL, Python, Spark, Trino, and modern orchestration frameworks like Airflow and Flyte to deliver reliable data systems.

I have led production analytics and ML-data efforts, creating standardized analytics frameworks, reusable dashboards, and observability patterns that accelerated experimentation and reduced engineering effort during feature launches. I built large-scale preprocessing and feature-generation pipelines for robotic perception, optimized data storage and query performance, and implemented automated dataset pipelines and quality checks.

I collaborate effectively with Product, ML, DS, and Engineering partners to translate ambiguous business and modeling needs into clear data outcomes. I thrive in fast-paced, high-ownership environments, consistently delivering high-quality engineering work under tight timelines.
