Summary
- I am a results-oriented Data Engineer and Analyst with over 4 years of experience in building and optimizing ETL workflows, data pipelines, and integration frameworks across healthcare, finance, and business domains. My technical expertise includes SQL, Python, and R, combined with strong skills in data modeling, schema design, and relational databases such as MySQL, PostgreSQL, and SQL Server. I also bring hands-on exposure to cloud data platforms including AWS (S3, Glue, Redshift), Azure (Data Factory, Synapse), and Google Cloud (BigQuery, Dataflow), along with familiarity in big data tools like Apache Spark, Hadoop, and Kafka for large-scale data processing.
In addition to engineering workflows, I have extensive experience in data analysis, exploratory data analysis (EDA), predictive modeling, and statistical techniques such as regression analysis, hypothesis testing, and A/B testing. I have successfully delivered projects in fraud detection, forecasting, and workflow optimization, leveraging machine learning and advanced analytics to provide actionable business insights. My proficiency in Power BI, Tableau, and Excel enables me to transform raw datasets into interactive dashboards and clear visualizations for stakeholders.
I am also skilled in data validation frameworks, governance policies, automation, and error-handling mechanisms, ensuring the accuracy, compliance, and reliability of enterprise data assets. With a collaborative background in Agile environments, I excel at translating complex business requirements into scalable technical solutions that enhance pipeline performance and support advanced reporting and analytics. Holding a Master’s in Business Analytics from the University of Alabama, Huntsville, I bring a unique blend of engineering rigor, analytical depth, and business acumen to deliver data-driven solutions that bridge the gap between raw data and strategic decision-making.
