At Citrix:

Citrix ADM Analytics
Citrix Application Delivery Management (ADM) is a centralized management solution. You can use ADM to manage, monitor, and troubleshoot the entire global application delivery infrastructure from a single, unified console.

My responsibilities and work included:
• Adding 'Horizontal pod autoscaling for ADM Agent'
• Adding 'Graph database (Neo4j)' to Citrix Analytics.

Citrix Cloud Native API Gateway
The Citrix API gateway provides a single entry point for APIs by ensuring secure and reliable access to APIs and microservices on your system. Because this catalog leverages the Citrix Ingress Controller, you need to create an instance of the API gateway CRD, which is the Citrix Ingress Controller.

My responsibilities and work included:
• Worked in the Citrix API Gateway team, where I wrote the Helm charts for the offering
• Published a Rancher Catalog and Openshift Operator.
• Worked on a TechFair idea: "Cost-optimized scalability of API gateway using FaaS". Used Azure functions for Faas.
• Enabled CORS in Citrix CN API Gateway: Adding a CRD in K8s to take configuration for CORS and configuring it with Citrix API Gateway product.

Citrix Ingress Controller
Citrix provides an implementation of the Kubernetes Ingress Controller to manage and route traffic into your Kubernetes cluster using Citrix ADCs (Citrix ADC CPX, VPX, or MPX).
Using Citrix ADC ingress controller, you can configure Citrix ADC CPX, VPX, or MPX according to the Ingress rules and integrate your Citrix ADCs with the Kubernetes environment.

My responsibilities and work included:
• Wrote a python based library to parse the language of the kubernetes labels.
• Wrote code for Route Sharding in Netscalar CPX (Similar to HAProxy).
• Added framework for API and System tests for Openshift based code of CPX.
• Worked on "Using Mutual TLS for API security for E-W traffic (intra-cluster) in a service mesh lite (hairpin) environment"
• Worked on integrating CPX with Openshift.
• Worked on Supporting Citrix stack in Openshift 4.x
• Worked on adding code for K8s service of type LoadBalancer into CIC.
• Enabling BGP in CIC, Advertise and Recall of VIP from ADC based on workloads.
• Adding TCP Profile in CIC.
• Worked on bringing K8s label awareness into Citrix ADC.

Technologies Used:
Python, Cloud, Kubernetes, Openshift (3.x, 4.x), Rancher, AWS, Azure, Docker, Load Balancer, Networking

At Veritas:

Data Ingestion for Multi-cloud Data Management Platform Product
Worked on building a Multi-Cloud Enterprise Data Management Platform Product in the Data Ingestion team. My team is specifically working on delivering the core data ingestion pipeline for the platform, deployed as containerized Java micro-services on Kubernetes.

My responsibilities and work included:
• Wrote the Java micro-service responsible for JanusGraph Queries. This service provides REST API endpoints to be called to query the asset from JanusGraph using Gremlin commands.
- Querying based on type of asset.
- Querying by applying filters to the asset.
- Querying based on output type that we are expecting for the asset.
- Querying based on a drilldown path of the asset from the type on which we are querying till the outputType supplied to the query.
- Support for Pagination in results.
- Support for Sorting in the query results.
• Worked on writing helm charts for deploying some of the projects micro-services on Kubernetes. • Worked on RabbitMQ deployment on Kubernetes.

Technologies Used:
• Java, Spring Boot, Kubernetes, Docker, Kafka, RabbitMQ, REST API, JanusGraph, Cassandra, Azure

At Veritas (Internship):

Using Cloud Custodian to Manage AWS instances at Veritas Cloud.
To write policies to manage different resources of AWS.

Technologies Used:
• AWS, Cloud Custodian, YAML

Continuous Integration Pipeline Development
Developed a deployment pipeline for the other developers to use at Veritas. The primary reason for developing this application is for the developers/customers to test their code in the simulated environment on their local system and not on the actual production pipeline, if their code works on our application in the developer's system then it will also work well in the actual production pipeline.

Technologies Used:
• Vagrant, Docker, Jenkins, Gradle, Packer, Gogs, Artifactory, Spinnaker, Shell Scripts

At Calsoft:

Windows Device in User Space (RnD_Win_DUSE)
Developed a Device in user space to get access to block data from user space in I/O path. Currently, Windows doesn't have the mechanism to get access to block data from I/O path in the user space. This is similar to FUSE in Linux which provides an access to non-privileged user to create its own file system in user space.

Technologies Used:
• Languages – C#
• Tools – Visual Studio 2013

Details of work done:
• Role: Sr. Development Engineer.
• Involved in Designing the product.
• Implemented the back end of the Cloud connector to AZURE cloud in C#.

Change Block Tracking for Hyper-V
The objective of this project is to build a Change Block Tracking driver which will keep track of changed blocks for virtual disks at run time (incremental backup). The product captures disk level backup of the guest OS installed on the hyper-visor. The backup application would trigger a snapshot event from which point onward all I/O operations needs to be captured.. The Pass-through mini-filter driver would trap all the I/O operations at file system level in (offset, length) format. This would then be converted to disk level (offset, length) format and sent back to the backup application.

Technologies Used:
• Languages – C, C++
• OS and Hypervisor – Win 2K12, Win 2K12R2, HyperV, Win 8
• Tools – VS, BugZilla, Driver Verifier, HCK kit, IO Meter.

Details of work done:

• User-space Logging mechanism implementation (in C++).
• Tools development for Testers aid.
• Performance monitoring and testing.

At UNC Charlotte:

Distance Vector Routing Protocol Implementation
A multithreaded application using UDP connection and socket programming in C#. The main idea is to find the minimum cost between each nodes combination in the system.
We have an input file where we keep the number of neighbors, the names of the neighbors, the port numbers of the neighbors. The input file basically acts as a forwarding table.
After every 15 seconds, we send out the current state of each node to all its neighbors. And, the receiving node will calculate the minimum cost to all the nodes, based on the received inputs from its neighbors.
I have used the Bellman-Ford equation to calculate the costs.
We can also edit the input file dynamically by updating the costs and the system will recalculate the costs and next hops based on the new values.

Technologies Used:
• Languages – C#
• Tools – Visual Studio 2015

Details of work done:
• Completed the whole project individually as a part of the course ITCS 6166: Computer Communications and Networks.

Socket programming was used to accomplish the task of communication between the client and the server. HTTP commands such as GET and PUT were used as the communication protocols.

Technologies Used:
• Languages – C#
• Tools – Visual Studio 2015

Details of work done:
• Implemented GET and PUT methods of HTTP/1.1 protocol using TCP connection and socket programming in C#.
• Completed the whole project individually as a part of the course ITCS 6166: Computer Communications and Networks.

Parallel Data Compression using LZMA
Now-a-days a tremendous amount of data is generated and shared per second, so there is real need of efficient data storage management and utilization of bandwidth.
Data compression is one of solution to this problem. Compression ratio and time required for compression and decompression are two main pillars of data compression. If either of the two gets hampered then data compression may be termed as inefficient.
LZMA (Lample-Ziv-Markov) is one of the finest algorithms for data, to be more precise, text compression in terms of compression ratio. But we found that it has not got that much amount of success due to its comparatively high time complexity for compression. We have improved its time complexity by implementing it in a parallel fashion.
GPGPU has provided a well-defined and economic path of parallel implementation to a computer community.

Here we have implemented a general data compression algorithm that has been designed by keeping in mind the parallel nature of the computing devices that we will be using. This, as we have discovered over the course of the project, not only decreases the compression time but also provides us with a compression ratio slightly better than that of LZMA.

Technologies Used:
• Languages – C
• Keywords— LZMA, CUDA, lossless data compression, GPU, BZIP2, GZIP.
