Experience
Disputes API – Platform for Customer Disputes in PayPal
https://developer.paypal.com/docs/api/customer-disputes/v1/A RESTful API that exposes an orchestration engine for customer disputes that can be integrated with enterprise clients to automate the dispute management process.
I designed and iteratively delivered multiple endpoints, including all the activities such as requirements elicitation, schema design, API development, unit testing, and functional testing. I also led the migration of a legacy SOAP service to a RESTful API.

Freshservice
https://freshservice.com/Freshservice is an ITSM product offered by Freshworks and has over $100 million in annual recurring revenue. It is a product built using Ruby on Rails and provides hardware and software asset discovery with integrations with multiple platform services for analytics, reporting, and activities
Multi-tenant Budget Allocation System Based on Heuristic Regression
Developed the core allocation engine in R, which uses historical data to perform the budget allocation. I modeled a graph-based validation engine and reduced the time complexity significantly to validate recursive rules. I improved the client-side's performance in a scatter plot involving visualization of multiple datasets by clustering based on a variant of a systematic sampling algorithm while retaining the patterns and information to be conveyed intact. I also developed the user interface to visualize stakeholder-specific data using Ember.js and D3.js.
Custom Web Dashboard Builder
Created a web application that enables the user to filter and, or select a set of data and represent the same using a wide range of charts and make projections to track milestones. I created the D3-based configurable charts in Angular. I added geo-navigation of the dataset by integrating OpenStreetMap with Angular leaflet. I also added the social media integration and sharing of the designed dashboard.
Ocean Tracking Logistics Web Application
Developed the Ruby on Rails-based application for tracking ocean loads in FourKites. I used the parallel processing capabilities of SQS to decouple the API and message processor.
