What I'm looking for

I seek a role that fosters innovation and offers opportunities for growth in data engineering.

I am a Certified Data Engineer with over two years of experience in building and optimizing data pipelines. My journey has been marked by a strong proficiency in Python and SQL, along with expertise in modern big data technologies such as GCP, AWS, Dataflow, and Apache Airflow. I have a proven track record of developing innovative solutions, including the creation of an AI tool called Hirebot, which automates resume matching and interview scheduling. This project not only showcased my technical skills but also my ability to work collaboratively in a fast-paced environment.

Throughout my career, I have been involved in significant projects like the modernization of National Grid’s data warehouse platform and the development of backend APIs using FastAPI and SQL Alchemy. My experience extends to data migration and pipeline management at Pfizer Inc., where I successfully tackled complex data challenges. I am committed to continuous learning and staying updated with industry trends, ensuring that I can deliver the best solutions to meet evolving business needs.
