About Myself

Hi I'm Ajay Krishnan! I believe in the fact that our lives are too short compared to the number of "Roads Not Taken". This belief coupled with three years of experience as an Undergraduate Computer Science student, internships and a wonderful side hustle experience has resulted in me analyzing and taking up the best techniques for everything I involve myself in.

I take a practical, data-driven approach towards any responsibiliy given to me while making sure that I give it my best towards my job. I like working on completely unrelated jobs to ensure maximum productivity and a chance to pick up more skills and meet more people along the way. In my freetime, you can find me building Deep Learning models, surfing the internet looking for ideas and papers or at a concert supporting the indie music scene. I also like learning more about languages and cultures and have a bilingual proficiency in Tamil, English, French and Hindi.
