What I'm looking for

I'm looking to lead scalable data-platform and GenAI initiatives where I can shape architecture, improve data quality and performance, and mentor engineering teams.

At Altimetrik, I lead the architecture of enterprise data pipelines and Medallion Architecture solutions across ingestion, transformation, and serving layers. I also built a Microsoft Teams GenAI chatbot using RAG, Snowflake, Databricks Delta, and the OpenAI API.

Previously at Optum, I led a Delta Lake migration that improved data processing performance and query speed by 70%. I built healthcare ML models, data-quality pipelines, ETL/ELT workflows, and Airflow orchestration for distributed datasets.

My background also includes backend automation, REST APIs, AWS serverless systems, Elasticsearch, SQL optimization, and engineering leadership. I focus on scalable design, clear standards, reliable data quality, and mentoring teams across the data stack.
