My goal is to use technology-driven innovation to solve some challenging problems.

I am an ambassador at DataCamp where I write about important concepts/recent discoveries related to Machine Learning. Apart from that, I handle some of its outreach campaigns as well. Currently, I am developing a project as a part of DataCamp Projects. Previously, I worked at TCS Research and Innovation (TRDDC) as a developer where the domain of work was Cyber Security (specifically Data Privacy). Prior to that, I worked as a Web Services Developer at TCS (Kolkata area). Data Science and Web Development are my subjects of interest. I am also working with Dr. Anupam Ghosh for Machine Learning research/tinkering (Currently working on the applications of Cyclical Learning Rate policies and Transfer Learning for Neural Nets on regular tabular datasets).

Ambassador at DataCamp

Jun 2018 - Present

I write about technical concepts/recent discoveries in Data Science and Machine Learning for DataCamp community (https://www.datacamp.com/community). I also prepare mini projects in order to accommodate the concepts in a meaningful way. Currently, I am developing a full-fledged project as a part of DataCamp Projects (https://datacamp.com/projects). The links to the blogs are attached herein that I have written for DataCamp till now. Many are in the process of getting published. I use Python, Jupyter Notebooks, Overleaf and FloyHub for writing these tutorials/posts. Apart from these, I handle few of the DataCamp's outreach activities as well. If you are a teaching individual of a university and want to set up DataCamp's online classroom (which is absolutely free) for your students feel free to contact me. Or if you are someone from L&D department of a company and want to know more about our enterprise offerings, contact me.
