What I'm looking for

I am looking for opportunities that foster innovation and collaboration, with a focus on data-driven decision-making and machine learning applications.

I am a dedicated Data Engineer with a strong background in developing and optimizing large-scale data warehousing systems. Currently, I work at Novartis in Tokyo, where I collaborate with cross-functional teams to translate business requirements into efficient technical solutions. My experience includes applying best practices in data governance and quality assurance, ensuring compliance and reliability across diverse data sources.

Previously, I served as a Clinical Database Programmer at Medpace, where I led the design and programming of edit checks for multiple studies, enhancing data accuracy and integrity. My commitment to excellence was recognized with a promotion after just 11 months. Additionally, I have experience as an AI/XR Researcher and Machine Learning Engineer, where I focused on innovative projects that leverage advanced technologies for improved decision-making and operational efficiency.
