What I'm looking for

I am looking for a role that fosters innovation, collaboration, and growth in data engineering.

I am a dedicated Data Engineer with a strong background in designing and implementing end-to-end ETL pipelines. My recent experience at Returnalyze involved creating robust systems to process large datasets, enhancing client engagement through automated reporting and notifications. I successfully led the onboarding of multiple retailer clients, showcasing my ability to manage complex projects and deliver valuable insights to stakeholders.

Prior to that, I worked at Verisk, where I optimized ETL processes, significantly reducing processing times and migrating legacy data to modern databases. My role at ExtensoData allowed me to develop a generic ETL pipeline for diverse client needs, ensuring data integrity and seamless automation. I am passionate about leveraging my skills in big data management and analytics to drive impactful solutions.
