Technical Stack: Ruby, Node.js, Salesforce Integration, Kafka, GraphQL

Contributed towards developing next-gen Configuration Management system for the applications in PayPal.

Configuration management system at PayPal offers applications a framework agnostic, extensible, external, and decoupled source of configuration, promoting rapid and reliable application behavior change at runtime without the need for application code changes.

Contributions to the project:

• Distributed system design and development of core components of UCP.

• Reduced the traffic on the database by incorporating distributed caching

using JunoDB.

• Designed and integrated "bulkhead" strategies for configuration rollout for safe and reliable configu-

ration changes.

• Brought down reverts of faulty configurations by 46%.

• Designed, documented, and implemented sidecar pattern for configuration agent decoupled from

application binary.

• Allowed abstracting stack agnostic client operations in a decoupled system.

• Simplified development, rollout, and maintenance of language-specific clients.

• Integrated with the automated change management solution for transparency of configuration

rollout across the site.

• Integrated with Jenkins automated pipeline to offer continuous linting and testing before production

changes.

• Developed thin client as an NPM package used by over 500 Nodejs front-tier and mid-tier applications

at PayPal.

• Integrated with identity management solution at PayPal to offer OAuth-based AuthN AuthZ for

client web app and server API.

• Contributed to uni-directional geo-partition strategies for configuration management across PayPal’s

US and China geo-locations.

Remote Config: Contributed to the modernization of the Remote Config system at PayPal. Remote

Config at PayPal provides dynamic configuration changes without downtime, allowing developers to

externalize and update configs swiftly and cleanly.

• Contributed to Spring Boot service for Remote Config takes an average of 44M requests every hour

and is served by 60 commodity-sized host instances.

• Worked as a full stack engineer on Nodejs web app and Java REST service.

• Worked on integrating with MongoDB servers for storing configurations.

Part of the Frameworks & Infrastructure team of PayPal. As an engineer in the Frameworks & Infra team, my responsibilities included developing and maintaining test automation frameworks and test infrastructure for PayPal's quality analysts to test the code.

Worked on core Java technologies to develop the test automation frameworks at PayPal. Along with the frameworks and infrastructure, I contributed towards building a metrics platform for my team which captured, persisted and visualized all the telemetry data for our frameworks and infrastructure.
