Data Engineer with 5+ years of experience in data solutions.
I am a Data Engineer with over 5 years of experience in designing and supporting data solutions for analytics and reporting. My expertise lies in working with large datasets and modern data tools, particularly in cloud environments. At Disney Streaming Services, I developed and optimized scalable batch and streaming data pipelines using Databricks and Snowflake, which significantly enhanced content engagement and conversion analytics.
Throughout my career, I have collaborated with both technical and non-technical stakeholders to gather data requirements and ensure alignment with business objectives. I have a strong background in ETL automation, data transformation, and building insightful dashboards using Looker. My experience at Caterpillar involved managing data ingestion pipelines and implementing ELT workflows, where I focused on optimizing query performance and ensuring data security through RBAC policies.
With a Master’s in Computer Engineering and a Bachelor’s in Electronics and Communication Engineering, I am well-equipped to tackle complex data challenges. I am passionate about leveraging data to drive decision-making and continuously seek opportunities to grow and innovate in the field of data engineering.
