I am adata sciencestudent studying atNew York City College of Technologywhile also studyingweb developmentin my free time who is eager to tell stories from data.

About Me


I am a third-year student at New York City College of Technology, CUNY and majoring in data science and interned at 2 companies in backend development and data analysis roles. I also am part of the 8th cohort of CUNY Tech Prep as a fellow and also an ambassador for CTP. I am passionate about learning more about this world through different lenses especially through data.

My goal is to discover, analyze and harness — the power of 'data'. Data is undoubtedly the new gold of the era we live in.

When I am not in front of a screen, I’m most likely enjoying the local food and wonderful weather while reading or listening to music.
