ETL/ELT Pipeline Development

Build reliable data pipelines using PySpark, Spark SQL, and Delta Lake. We design for idempotency, incremental processing, and graceful failure handling—because pipelines that "usually work" aren't good enough.

Pipeline Orchestration

Design and implement orchestration patterns using Azure Data Factory, Databricks Workflows, or Airflow. We build dependency-aware scheduling, monitoring, and alerting that keeps data flowing on time.

Cloud Data Platforms

Implement and optimize cloud data infrastructure on Azure and Databricks. We configure clusters, storage, networking, and security so your platform performs well and doesn't blow past budget.

Real-Time Data Streaming

Build streaming pipelines using Spark Structured Streaming, Event Hubs, and Kafka. We implement exactly-once semantics, watermarking, and windowing for use cases that can't wait for batch.

Data Quality & Testing

Implement data quality frameworks using Great Expectations, Delta Live Tables expectations, and custom validation. We build tests that catch problems before they reach dashboards and downstream systems.

Performance Optimization

Diagnose and fix slow pipelines. We tune Spark jobs, optimize Delta table layouts with Z-Ordering and partitioning, and right-size clusters to cut costs while improving performance.
