Sreejit Roychowdhury

I am a software developer having 5 years of experience specializing in Cybersecurity specifically development and custom implementation of Identity & Access management products both on premise and cloud.
My areas of interest are in the field of image processing, cryptography, machine learning and distributed systems.

In my undergraduate I developed a keen interest in the field of cryptography and machine learning which led to publication of two research works in the same domain. I had also undergone a summer internship at Indian Statistical Institute, Kolkata, Machine Intelligence Unit where I worked in the domain of image watermarking and overall increasing the efficiency and security of various watermarking algorithms using machine learning algorithms.
