Virtual Component Guard: Prevented minor and major bugs during review of design and code for Certificate Management module

CMP Application Refactoring: Successfully led the project of Certificate Management Module refactoring for Small Cell BTS which included design review, mapping of old requirements for new design and implementation using C++ 11.

ACADEMIC PROJECTS

Bitly Clone [URL shortening application]: Developed multi-tiered URL shortening application using Golang, MySQL, Riak, RabbitMQ, Kong API Gateway. Used Golang to implement REST microservices which are Control Panel Server, Link Redirect Server, and Trend Server. Used CQRS and event sourcing design pattern. MySQL and Riak for database cluster, RabbitMQ for message exchange between servers and Kong for API Gateway. Packaged the app into Docker containers and deployed on AWS EC2 instances.

Zipcar Prototype: Developed prototype of Zipcar using React, Node, MongoDB for a group project. Used Node to write REST API for backed microservices, Mongoose for creating MongoDB data models. Packaged the application in Docker container and deployed on AWS.
