Throughout my career, I’ve worked with a variety of tools and technologies, including AWS and Azure, to design, build, and optimize scalable data pipelines.At CapitalOne, my focus has been on developing ETL pipelines using AWS Glue and Redshift, which significantly improved our data processing speed by 40%. I also work with AWS Lambda and serverless technologies to keep our systems efficient and responsive. My work doesn’t just stop with AWS; I’m also experienced with Azure’s powerful suite of tools like Data Factory, HDInsight, Blob Storage, and Azure Functions. These tools have been instrumental in creating robust, scalable solutions that meet diverse business needs.Before my time at CapitalOne, I was at the Mayo Clinic, where I played a key role in building data pipelines for healthcare analytics. I leveraged Apache Spark, Sqoop, and various Azure services to integrate and manage complex datasets, which helped support better decision-making and patient care.I thrive on finding innovative ways to improve data architecture, ensuring that data is accurate, secure, and accessible. Whether it’s working on Azure or AWS, I enjoy collaborating with teams to implement best practices and drive impactful results. My goal is always to make data work smarter and harder for the business.If you’re into data engineering or have opportunities where a data-driven approach could make a difference, I’d love to connect and chat about how we can make that happen!
