What I'm looking for

I seek a role that fosters innovation and allows me to leverage AI to drive impactful solutions while promoting continuous learning and collaboration.

I am a Data Scientist with over 5 years of commercial experience, specializing in leveraging AI and analytics to solve complex business challenges. My journey has been marked by a commitment to excellence in development, particularly in Python, where I have successfully built end-to-end machine learning projects capable of processing vast datasets.

At Talent Shark, I developed an LLM-powered tool for automated job-candidate matching, which significantly improved the precision of candidate selection. My role at BNY Mellon involved creating intelligent agents for data analysis, enhancing decision-making through advanced visualizations and statistical metrics. I am passionate about continuous improvement and have consistently achieved remarkable enhancements in model accuracy and performance through rigorous analysis and retraining.
