What I'm looking for

I seek a role that challenges me to innovate and streamline data processes, ideally in a collaborative environment focused on impactful projects.

I'm a Senior ML & Data Engineer with a decade of experience in architecting scalable ETL/ELT pipelines and deploying innovative ML models across various sectors, including healthcare and gaming. My passion lies in transforming complex data into actionable insights that drive better outcomes. I thrive on designing real-time streaming pipelines in the cloud and tackling NLP and computer vision challenges, ensuring that data works smarter and faster for everyone.

At Cigna, I developed secure ETL/ELT pipelines that achieved full HIPAA compliance while processing multifaceted healthcare data. My work improved data consistency and predictive model accuracy significantly. I also led initiatives in Generative AI and containerization, enhancing the cloud infrastructure and automating clinical workflows. My previous role at Niantic involved creating real-time data pipelines for AR games, where I optimized data architectures and implemented machine learning models that increased player engagement and retention.

With a strong foundation in data engineering, machine learning, and cloud platforms, I am eager to leverage my skills to deliver intelligent solutions that improve lives. I am always looking for the next challenge that allows me to innovate and streamline processes, making data work for us in meaningful ways.
