What I'm looking for

I seek a role that challenges me to innovate with AI while fostering collaboration and growth.

My journey in technology began as a Full Stack Developer, where I discovered my passion for coding and creating applications. However, it was my exposure to data that truly ignited my career shift towards Machine Learning Engineering. Over the past nine years, I have honed my skills in healthcare, fintech, and manufacturing, developing predictive models, NLP systems, and GenAI applications that have significantly impacted business outcomes.

At DataRobot, I led the development of LLM-based applications that improved enterprise data access by 40%. My work has consistently focused on transforming complex problems into actionable solutions, such as optimizing AI operational workflows that resulted in over $1.2 million in annual savings. I thrive on the challenge of using AI to enhance various sectors, from financial advising to healthcare, and I am excited about the future of technology and its potential to drive meaningful change.
