Apache Airflow & Pipeline Orchestration
Design and optimization of complex data pipeline orchestration using Apache Airflow, Control-M, and AWS Step Functions. Tuning of multi-schedule dependencies covering 90+ tables and 10+ pipelines, with virtual environment provisioning enabling sub-minute setup times.

Python & SQL Development
Advanced Python scripting for data reconciliation, pipeline automation, and ETL processes. Complex SQL development including stored procedures, transformation logic, and data extraction across SQL Server, Oracle, Redshift, and Snowflake.

Power BI & Analytics Reporting
Development of Power BI semantic models, DAX measures, paginated reports, and deployment pipelines with row-level security and governance controls. Experience with SSAS Tabular models, Power Query, and DAX optimization.

AI-Augmented Development & Prompt Engineering
Application of AI-first engineering practices using GitHub Copilot, Cursor, and MCP (Model Context Protocol) to accelerate dbt model delivery, SQL pipeline generation, and Power BI report development. Creation of structured prompt libraries for dbt macros, SQL refactoring, and reconciliation logic.

CI/CD & DevOps
Setup and management of CI/CD release pipelines for data and Power BI deployments using GitHub Actions, Azure DevOps, and AWS CDK/CloudFormation. Automated failure alerting, retry logic, and infrastructure-as-code provisioning.

Data Vault Modeling
Design and implementation of Data Vault raw vault loading pipelines including CDC (Change Data Capture), data lineage, and business vault business rules. Delivery of reconciliation frameworks validating migration outputs against acceptance criteria.

Spark, Kafka & Streaming
Experience with Apache Spark, Spark Streaming, and Kafka for large-scale data processing. Built Azure Data Factory pipelines processing 7 million semi-structured files using Spark Streaming with config-driven scaling.

Oracle & Legacy System Integration
Senior Oracle development and technical business analysis, including reverse-engineering legacy data warehouses, forward-engineering improved data models, and building custom Power BI visuals using TypeScript and D3.js.
