About Me [📌 This site is deprecated]


Hi! I'm a graduate student based in Chicago, IL, currently pursuing Master of Science in Computer Science at the University of Chicago.

With a focus on Full Stack Development, including both Web and Mobile Applications, I strive to create innovative and impactful software solutions. You can see some of my work by browsing my applications available on AppStore  and here. In my free time, I write blogs and I am also a technical writer for @BetterProgramming, @JavaScriptInPlainEnglish and @BitsAndPieces on Medium . Besides coding, I'm a 3000m steeplechaser in my college varsity Track and Field team. Recently, I'm learning Spanish and training Muay Thai at Chicago Aiki Training Hall, which I find both challenging and rewarding.
