What I'm looking for

I seek a Data Engineering role where I can build scalable pipelines, apply QA and CI/CD expertise, work in Finance or Healthcare, and grow technically while delivering validated data for analytics.

I am a Data Engineer with more than six years of hands-on experience combining data engineering and QA expertise to deliver reliable, validated data solutions for Finance and Healthcare.

At S&P Global I developed and optimized data ingestion pipelines to extract from APIs, transform using Apache Spark, and load into Oracle, and I designed Spark-based data validation workflows to enforce integrity and reduce latency.

I automated end-to-end CI/CD for Spark jobs using GitLab and integrated Control-M with CI/CD to orchestrate batch jobs, improving operational efficiency and monitoring; previously I led automation testing and QA workstreams at Deloitte and Cognizant.

I bring strong skills across big data technologies, cloud, testing frameworks and observability tools, and I am committed to bridging QA and engineering to deliver accurate, production-grade data for downstream analytics and reporting.
