About

I'm a passionate Data Scientist with a strong interest in the rapidly evolving fields of AI and LLMs. I spent a year at Turing building high-quality datasets to fine-tune LLMs in the coding domain. Moreover, I worked at TCG Digital Solutions as an intern and built a Python-R data exchange pipeline using TCP socket and Apache Arrow. As a consulting intern at Marktechpost, I translate cutting-edge AI research papers into accessible and engaging articles for a broad audience.
