• Bring your own key (BYOK) for Elasticsearch for Jira and Confluence products
• BYOK enables Atlassian to implement encryption at the tenant level where each tenant's data is encrypted with their own key and enables them to revoke keys at any time to revoke access. This encrypts data such that even Atlassian doesn't have access to the tenant's data. Moreover, in case of a data breach, the offender can't get hold of all data because each tenant's data is encrypted with a different key.

• Rebuilt Sears and Kmart OMS platforms from scratch. We migrated all functionality from Websphere and DB2 to an open source platform consisting of JBoss and MySQL.
• In this position, some of my specific accomplishments include:
• Creating a scalable OMS platform using Database Scaling.
• Creating a highly robust and fast Search Infrastructure using Solr.
• Converting application from single-tenant to multi-tenant application using SOA.
• Creating a team of highly motivated self-sufficient engineers at Sears on-shore and off-shore facilities.
• Evangelizing various scaling and SOA strategies to better systems across the organization.
• We also built Transaction Risk Management System, a first at Sears. As part of TRMS initiative, we are proving software systems using machine learning that identify and prevent fraud and abuse. TRMS will leverage Machine Learning algorithms like Support Vector Machines and Artificial Neural Networks for classifying transactions based on probability of fraud.
