PROFESSIONAL PROJECTS

Implementation of Data Pipelining and Authentication Service: Developed a Micro Service for Authentication gateway using Kong-Client and version controlling and propagation. Using streaming Frameworks, such as Kafka, to pass the commutation between different Microservices. API driven digital Banking:

This digital solution is divided into two parts Controller (for FI) and Banking (end user) module which makes “Develop once and sell to anyone”. Each customer can be customized (look and feel, enable and disable) as they wish without changing the code which saves lot of developer hours and cost effective.

Information TV:

Developed a web application called Information Television (ITV), which enables to share information across organization or within the group or team by displaying real time information on ITVs across the locations, using JAVA spring MVC as backend and Angular JS as front end, my application takes video, image and text as input to render it on ITV and avoids manual intervention by enabling self service capabilities and also supports content from Content Management system. Calendar Ordering System:

As per of the Internship at Union Pacific Developed a Calendar ordering system using Angular JS and J2EE. Which enables for internal customer to order calendars for business partners and fixing the issues in the existing application.
