Staff-level data engineer with 8+ years building and modernizing data ecosystems for big tech companies like Netflix and Etsy. Focused on the hard, high-scale problems: re-architecting orchestration, migrating thousands of tables to open table formats, and cutting the cost and latency of massive Spark workloads. I’ve worked remotely with US-based teams since 2018.

Work Experience
Senior Data Engineer
Netflix
- Built customer acquisition funnel analysis for partnership channels, informing negotiations on million-dollar contracts with strategic consumer electronics partners.
- Rebuilt core experimentation and performance-analysis tables, cutting data latency from 2-3 days to under 3 hours, accelerating go-to-market decisions across Commerce and Finance.
- Built a partnerships MCP server unifying docs, repos, Slack, and live query execution, with source citations on every answer to curb LLM hallucination. Adopted initially by a dozen key stakeholders.
Staff Data Engineer I
Etsy
- Re-architected Airflow on Kubernetes (GCP) through a multi-year effort with Engineering, Data Science, and Analytics Engineering, achieving zero-downtime migration of thousands of critical workloads, resilience to cloud outages.
- Authored the multi-year plan to migrate batch data to Apache Iceberg, across thousands of TB-size tables across engineering, data science, and analytics engineering teams, projected to save 100s of thousands per year in storage and compute.
- Extended an org-wide Spark job analyzer with data skew detection and input/output extraction, helping teams cut costs by an estimated 20% and laying the groundwork for job lineage.
Data Engineer with experience Scaling Data - PT/FT
CRED
- Migrated dozens of data science pipelines from pandas to Spark and automated their execution, cutting runtimes from 8+ hours to under 2 hours and speeding C-level analysis of partner contracts.
- Architected a scraping and enrichment pipeline processing ~100M records to infer user age, gender, and geolocation, feeding a knowledge graph and ML models linking individuals to sports interests.
- Automated data movement across RDBMS and lakehouse engines with Airbyte (10 connectors initially), enabling self-serve downstream access for data science, product, and engineering teams.
Staff Data Engineer
Wizeline
- Re-architected a fintech’s data warehouse into a Bronze/Silver/Gold lakehouse on Delta Lake, enabling risk analysis and paving the path for streaming ingestion for loan data.
- Designed and led a data engineering bootcamp that transitioned 30+ software engineers into data roles.
- Architected an IoT cloud ingestion and monitoring solution for several million devices in collaboration with the SRE team. The project successfully kicked off, and a dozen engineers were assigned to it.
- Conducted technical kickoff sessions with customers like Etsy and a few Fintech companies, in collaboration with Architecture and Business Development, to scope multi-year data projects.
AWS Big Data Architect
Triolabs
- Implemented a service to ingest and prune brain imaging data from private laboratories in near real time using Apache Kafka and Python on AWS. The resulting data was consumed by a machine learning model in R to extract insights from the scans.
- Rearchitected a data warehouse data model to handle TB scale queries faster and speed up a drug research analysis.
- Coordinated a team of two to create aggregation pipelines on Apache Spark on the brain imaging results so that the researchers could fine-tune drug research.
Big Data Engineer
Apex Systems
- Developed over ten Spark pipelines to aggregate and store TB of data to Hive, Elasticsearch, and MongoDB for the marketing team. These aggregations were exposed via APIs, enabling the analytics team to generate campaigns to attract new users.
- Created a library for Spark jobs to efficiently enrich data sets with location data from Google Maps APIs, thus allowing for better-targeted marketing campaigns.
- Optimized Spark settings of several production workloads. Reduced cost and execution time of overnight execution to a third, minimizing report delivery delays to senior management.
Embedded Software Engineer
Continental Automotive Systems
- Developed a data pipeline in Hadoop MapReduce to aggregate historical cellular network data, helping to reduce errors in a middleware service by half.
- Architected and led the development of a service to automatically re-configure a car while driving and seamlessly connect back and forth between cellular stations.
- Assisted in containerizing the development environment of people in my area, effectively helping reduce pain and setting up a stable environment.
- Gave a series of training sessions for 30 developers on unit tests and coverage using a proprietary tool. Helped remove dozens of unreachable code snippets.
