Vinay Keerthi K. T.

Experience¶

GKN Aerospace India / GKN Driveline¶

Developer

Joined: December 2015

This role involves various development activities, mostly handled independently. I was recruited as the sole developer for the business in India. I have fun coding complex pipelines, tools for unique engineering usecases and engineering a data flow system.

Flipkart Internet Pvt. Ltd.¶

Copy Editor / Developer

February 2014 - November 2015

Working for the Catalog function of Flipkart, I was tasked with building tools and scripts to help content writers in their daily tasks.

Projects	Contribution/Activities	Benefits
OINK Work Management System for Writers	Created a tool to enter daily work, record content metrics such as grammar, word count, SEO scoring from an internal algorithm and to prevent duplication of work across the function.	This tool simplified the team leaders’ work. It reduced duplication and conflict in work from an average of ten times a month to zero. The tool simplified gathering metrics for articles and allowed the team to focus on writing great content.
LEONARDO USP Image Creation Tool	Created a tool that was used to generate images that could educate buyers about the key selling points of a product without having to read the content or specification sheets. Created an MS-Excel based templating system wherein Subject Matter Experts could decide what key selling points to place on the image, and how the product image could be positioned. Automated the entire workflow so that images of top quality could be produced. Tool was developed with Python and PyQt.	This helped buyers make educated choices in a few seconds. SMEs were able to develop various templates in a few minutes and using the icons created by graphics designers, five thousand product images could be generated in five minutes. This prevented the company from having to outsource the work at a price of 60INR per image. The third-party company could also only deliver 500 images a week. This tool could do 10x that in five minutes, at no additional cost. The tool was used to meet the target of creating 600,000 product images in four months, as opposed to waiting a year to do it, at an exhorbitant cost.
Adhoc-Scripts/Tools	Created scripts to apply season labels to 500,000 apparel images.	Tool could identify white spaces and apply the logo where the image was empty.
