Microsoft, Redmond, WA (Remote – Contractor - RPNC Systems. Inc (Mindtree) Employee)

.Net Azure Developer

September 2020 – March 2021

Worked independently in an existing .Net Application with Angular as front end and Web API in service layer to add new features and functionalities. Upgrading to the latest Angular version (From V5 to V10) was under process. Done enhancements in UI Layout and modifying features to the current need in displaying data in report format on the dashboard. Required updates needed in back-end Web API code and stored procedures are handled for new features in given new requirements. Worked with database team to feed the required data needed for the new requirements fulfillment. I have identified the needed data requirement by doing analysis of the entire application and data from UI to Backend data in database. Submitted report to the Project head with a supporting document at the end of the project to have a reference for the future developers who would work on the further developments in that stand alone application. The big challenge was working in an application handled by many sets of developers earlier without having an source control software. It was a real challenge in understanding the history of changes done in that application in Production in the past few years by having chain of meetings with ex-developers who are in both offshore and onshore in difference projects currently. Entity relationship Diagram with all related tables were made for future reference as there were no other documents to refer so far for any developers to refer. Designed the high-level design document to cut down their analysis phase in any further developments.

Worked in a development team for automation of an application which is running on manual efforts to add data into configuration database. It is an enhancement to an existing application which updates Kusto database with a set of client data from Azure client Identity Management System (logins). Joined the team during analysis phase. We helped the clients to locate the reasons behind shutting off time and the issues related logins filtered from the Azure backend Kusto database using Power BI Reports. From the drill down report, clients can assess the things to be done to prevent power down on any region. We made changes requested by clients on existing power bi reports to create reports for their analysis to develop a design document for development phase. We were setting up a Service Engineering Solution, the existing .Net Azure application which needs automation in Corext Environment. Installed all required Nuget Packages for the solution in Package Manager. We created a setup document based on the issues we faced while installing and setting up the application in our system. We ran CLI commands to init, build the application.

New Development:

Every time the application adds data to the Kusto database, it requires manual human intervention to enter the Azure credentials to authenticate the data updates to the database. During the development phase, we worked on automate this process by adding the azure identity collected from the very beginning of the application in place of requesting in between the process. We saved the credentials in the history file for future reference.

Worked on a team doing automation and efficiency enhancement of Power shell scripts running manual by a team of people for 180 hours max every month to copy and restoring 738 Azure Production Databases into Data Transfer Request Environment to extract reports based on Azure Clients requests. Actively involved in the analysis, design in bringing out new thoughts to help the team in the long run as well as in initial development phase of this project.

Worked on a work item to update an ARM template to Integrate IPv6 feature by upgrading an IPv4 application to IPv6 in Azure Virtual Network, hosting dual-stack (IPv4+IPv6) VMs. During analysis stage, I explored Azure public documentation to explore ARM template. Needed to deploy a new VM to support IPv6.
