Internal AWS Service

I designed and developed multiple services being used internally in AWS. These scalable and highly available services are built on other popular AWS Services like DynamoDB, S3, Redshift, Lambda, SNS, SQS, and more. These services are used by service owners internally at Amazon on a daily basis.

Improving Microsoft Office Android Applications

Through a deep understanding and knowledge of the Android system, I was able to achieve a 62% reduction in the application package size, 25% improvement in application start-up performance, and sizable performance improvements in other scenarios like file opening, typing, and document saving.

Microsoft Word on Android

As the spearhead of the development team, I solved some really challenging problems to make this project a success. I explored the deep nuances of code-sharing across multiple platforms, adapting the code to the Android ecosystem, and fixing some difficult bugs using my deep understanding of the Android system—these were some of the skills that I demonstrated throughout this assignment.

Word Web Pagination

I was given a challenging problem to introduce page-beginning and end indications on a document rendered using the Word web application. The problem was challenging due to the existing design and back-end support. I worked out an elegant solution involving changes in server and client architecture to deliver the feature ahead of the expected timeline.
