Case Studies
Hybrid Analytics

Platform Modernization→

On-prem environment lacked interactive compute. Enabled scalable data science with significant cost avoidance vs Databricks.

Kubernetes, Trino, Airflow
Streaming

Ingestion Reliability→

Missing/late events in payments data streaming. Implemented idempotency achieving zero data loss during ingestion spikes.

Redis Streams, PostgreSQL, Python
Governance

Enterprise Metadata & Lineage→

High change risk during migrations. Implemented catalog + lineage + governance saving hours/week across teams.

Work Experience
07/2024 - Present

Vesta Corp

Principal Data Engineer

Owned payments and finance data platform modernization processing 5–7M txns/day. Built streaming durability on Redis Streams, migrated analytics workloads to a hybrid on-prem Kubernetes/Trino ecosystem (cutting compute spend ~85%), and implemented OpenMetadata for automated lineage and governance. Led a 5-engineer squad across multiple projects.

11/2023 - 07/2024

Nationwide Insurance

Staff Data Engineer

Led enterprise migration from Hive Metastore to Unity Catalog, standardizing RBAC and policy controls. Implemented Lakehouse Federation patterns to enable cross-source discovery and developed an automated PySpark data quality framework across Delta Lake and Snowflake feeds.

10/2022 - 11/2023

Hyundai Autoever America

Lead Big Data Engineer

Architected ingestion pipelines supporting 65 on-prem Hadoop clusters for connected car and AI services. Rolled out Trino/Presto distributed SQL layers to reduce transformation overhead and empower ad-hoc analytics at scale.

01/2020 - 10/2022

Nationwide Insurance

Senior Data Engineer

Built multi-TB/day ETL into S3 and Delta Lake on AWS. Created a standalone PySpark validation framework to guarantee post-run integrity, and tuned Spark clusters for massive throughput and memory stability.

12/2018 - 01/2020

Santander Bank

Data Engineer

Built scalable Hadoop and Spark environments for model development workflows and production data processing. Modernized legacy Hive and SQL logic by converting pipelines into PySpark and Spark SQL.

CostOptimization

Platforms & Paved RoadsOnboarding new datasets in < 1 day. Building frameworks that allow analysts to ship safely and independently.

Streaming ReliabilityIdempotency, replayable queues, and late-event handling. Utilizing Redis Streams and Kafka to ensure exact correctness.

Governance & LineageImplementing OpenMetadata and Unity Catalog alongside automated data quality checks tailored for finance-grade compliance.

Lessons Learned

  • Designing reputation systems requires severe rate-limiting to prevent sybil attacks.
  • Geospatial querying at scale demands specialized indexing (PostGIS).

Lessons Learned

  • Optimistic UI updates are critical for a responsive feeling in multi-player state apps.
  • Complex household rules engines scale best with event-driven architecture.
