I improve large language models and apply market analysis to investment decisions.
United StatesWhat I'm looking for
I'm currently improving the safety, accuracy, and helpfulness of large language models at DataAnnotation through Reinforcement Learning from Human Feedback.
Previously at Welocalize, I labeled data for machine learning tasks, researched complex questions, evaluated language and cultural appropriateness, and reported bugs while meeting quality standards.
As a self-employed asset trader, I performed technical and fundamental analysis across stocks, futures, cryptocurrencies, and options. I managed multiple portfolios and outperformed the market by 700% in 2021.
My earlier sales experience at David McDavid Nissan strengthened my customer communication, CRM, and buying-experience skills, earning multiple Top Sales Performer recognitions.
