• Designed a solution for the migration of conventional HTML editors on web-pages to latest rich text editors for the more consistent end-user experience. This solution spans both the frontend and backend and involves an extensive understanding of both the layers of web development. Implemented a react app from scratch to integrate Rich Text Editor (Draft-Js) from Facebook, on server-driven web-pages. This app is bundled in chunks with Webpack and deployed to Amazon S3 for hosting.
• Designed a 3-month long UI intensive feature, led its development process and now the functionality is in production. UI was built on React and Redux and was profiled and memoized to achieve smoother performance for the end user. This feature aimed at improving user-experience by allowing easier designing of HTML forms. The complexity can be deduced from the fact that it required handling different business rules for more than 50 independent items. Built a generic solution for all the items currently in use and other items that may be added later on.

• Designed and led the development of an async task consumer Java application, which subscribes to RabbitMQ queue for messages containing metadata for tasks to execute and pulls and pushes data to Postgres database for persistence and uses Couchbase for maintaining transient states. The system is fault-tolerant, scalable, throttled, robust and well-monitored. This Java service is being hosted on AWS EC2. The system is generic and can be easily extended to support any number of async tasks. Currently, this service handles two important actions, one dealing with huge datasets and other dealing with a huge number of requests.
• Designed and implemented a solution for bulk download functionality which enabled downloading multiple files, from multiple file sources like Amazon S3 and custom hosts as a single zip, similar to that provided on Google Drive, but in this case, the solution caters to multiple file hosts. It also supported hashing to identify same download requests and hence save on storage and network resources, along with providing a better user experience.
• Performance analysis of the application critical endpoints with Gatling, identified bottlenecks and tuned both the storage and service layer for improving performance by a factor of 100 in some instances.
• Writing unit and integration tests with JUnit and Mockito.

• Worked on two projects – C-App and MVC Redesign. Got a job offer after the completion of the internship.
• C-App was an internal android social networking app for company employees. Was the sole developer on this project and implemented major features like creating, liking, following and sharing posts and the ability to comment on these posts. It had a PHP/MySQL backend.
• MVC redesign was migrating existing .net webpages to C# as per MVC methodology. Also worked with the Localization framework and implemented a client-side version of the same.
