Helping all AWS customers to reduce their bills by allowing them to analyze their cost/usage, and also recommend them to buy cost saving AWS offerings. Enabling customers to maximize their return on investments of their cloud investments by ensuring that their AWS environments are sized correctly for their workloads, and helping customers adopt the most cost optimal pricing model for their long-term needs.

Georgia Institute of Technology - USA

Graduate Researcher | 2019 - 2020

Worked on applying machine learning and optimization skills in method development and data analysis for single-cell RNA-Seq data and other types of data on single cell level. The goal is to study cellular mechanisms during differentiation, development of cells and disease progression.

TESCO Technology - India

Software Developer | 2018 - 2019

As a member of the Data Platform & Analytics team at TESCO, one of my major project was to develop a parser to help automate the translation of queries from Teradata SQL to Hive SQL so as to facilitate the execution of sales and analytical models on Hadoop and save subscription costs.

CIRAD (LIRMM), University of Montpellier - France

Visiting Intern | 2017 - 2018

Developed new techniques and an application to help epidemiologists at CIRAD (French Government's Agricultural Research Centre for International Development) analyse the patterns and causes of various diseases which is being currently in use at the institution. The work was consolidated in a research paper which was accepted at VINCI '18 and can be found here.

CeADAR, Dublin Institute of Technology - Ireland

Summer Intern | 2017

Developed Explorobot from scratch, which is an Automatic Data Visualiser and Navigator. It helps data analysts by replacing the bulky traditional visual analytics softwares with the intuitive & adaptive experience.

cBioPortal, Memorial Sloan Kettering Cancer Center - USA

Google Summer of Code Intern | 2016

The primary aim of this project is to improve the cBioPortal's clinical-timeline used by over 10,000 researchers and clinicians monthly. This was undertaken as a part of Google Summer of Code project using d3.js and is currently in production.

"I rarely come across real talents who stand out like Rohan. I had the pleasure of working with Rohan for 18 months at the Tesco, collaborating on big data project. Rohan's ability to pickup requirement and execute it with perfection, during course of execution he brings lot of innovative ideas, he is always ready to put all his energy and time to get the job done. As a team member Rohan earns my highest recommendation."

"I met Rohan in 2017, when he came for a few months in my lab (LIRMM-University of Montpellier, France) to work for an internship on a visualization project. He did a great job. He perfectly understood the end users (epidemiologists) needs, and he designed and developed a sound application. Epidemiologists really liked it - they found it powerful and currently use it in their daily work. Also, we published a paper at VINCI 2018 presenting the approach - VINCI is an international conference on Information Visualization. It was a great pleasure for me to collaborate with Rohan and I highly recommend him."

"Rohan developed the ExploroBot Application during his time at DIT. In a short time frame, he developed a sophisticated application with multiple layers of logic, UI and Data management. He has an excellent work ethic and is a pleasure to work with. I recommend him thoroughly and hope, at some point in the future, to be work with him again."

"During GSoC 2016 I was Rohan's mentor. Rohan showed both an eagerness to learn and exceptional management skills. Even before GSoC started, Rohan contributed to our code and made the best proposal of all the ones we received. Once GSoC started he made sure to reach the set goals and deadlines with only little guidance. Since all the organizational aspects were taken care of by him, I could focus on reviewing his code contributions. He was able to quickly deliver the features that were requested leaving plenty of time to refine the code further. My comments were always received very positively and I did not have to make any comments twice. Rohan picked up new concepts every week without much effort and with great enthusiasm. It was a pleasure to work with him."

"Rohan worked under my supervision in ValueFirst, on a product named "Revide". During this time, from design to development, he worked very actively and smartly. His quick grasping and innovative ideas helped us to develop our product and make it more functional. His willingness to work will help him in future."

"Rohan is an awesome mentor; he gave me a lot of advice and knowledge on the Amazon interview process and how to prepare. He talked about the LP's they asked, how they set up their interviews, and all the knowledge I really needed in preparing for my new grad interview with them. He also gave me advice on how to continue relationships with your mentors and the people you meet and overall he came off as very genuine and kind. We continued our conversation naturally after the advice too."

Student, Purdue University, USA

"Rohan had a ton of insight into engineering, management, hiring, and collaboration in the world of tech and Amazon. He offered knowledge about what it means to build at scale, especially for a product like AWS, and discussed the nuances of what startups, medium-sized companies, and large companies look for in teams/talent. I'd recommend Rohan to anyone interested in understanding the systems and processes that go into creating large-scale software."

Eric Pan

Student, Yale University, USA

"Rohan was very easy to talk to and he is defiantly the type of person people can look up and ask advice. He gave great pointers and recommendations during our meeting. I highly recommend anyone getting a chance to speak with him."

Arya B

Software Engineer, TROAGEE, USA

"I had a great session with Rohan. He advised me with a few approaches to get a entry level position as a SWE. One of the approach that I did not consider was to enroll as a student. The reason behind it is that some companies would rather train a new grad so it could potentially be easier to get a position in that route."
