About Me

Hi, I'm Shreayan. I was born and brought up in Mumbai. I am 25 years old. I am a fun-loving person who likes to travel, eat delicious food, meet new people, and listen to all types of music. I have graduated with a First Class with Distinction in B.Tech in Software Engineering from SRM University, Chennai. I love coding and my areas of interest include Machine Learning, NLP, and Data Science. I started coding in 2012 when my class teacher introduced me to it. My love for coding has only improved over the years. Call me a fanatic, but I'm crazy for all things related to Space and Astronomy. I love researching random stuff in Astronomy and Space, which often gives me existential crisis. My hobbies include playing video games, chess, football and cooking. In my free time, I also play various songs on the keyboard. Do check out my Instagram if you want to check out how I play the keyboard.

Skills

I started my coding journey in 2012, when my class teacher introduced me to it. My love for coding has only improved over the years. I started coding with Java in 2012. After that, I learned the basics of C and C++. Then I moved on to HTML, CSS and JavaScript to create fluid, mobile responsive and lightweight web applications. When I was introduced to Python by a friend, I immediately fell in love with this language, and it has been my favourite language since. I have dived deep into deep learning (pun intended) and started learning machine learning (also, pun intended) in Python. My area of research lies in Recommender Systems, OCR and NLP.
