The application is used to create a shipment for the customer. And the main modules are know asDSC, TM Adapters, TP Adapters.

TM: Transport Manager

TP: Transport Planner

DSC: Direct Service Controller.

NDS Update Client is a lightweight library, which implements NDS Update Architecture and can be used to fetch and install updates for NDS maps from TomTom Server (TomTom Dutch company that produces traffic, navigation and mapping products). The library is implemented in C++, it is mostly platform independent and has almost no external dependencies. NDSUC-Navigation Data Standard update client

The NCR Gateway is used to facilitate the customer/employee to access the internal applications when they are outside of the organization network. Internal applications like HR-Portal, Payroll-Portal. Technically, The NCR Gateway Application is a WEB service and act like Load balancer, reverse proxy and URL Parser. Another strong feature of this application is, it works as URL Parser(Encrypt/Decrypt) so that the users cannot hack the server-details. NCR Gateway Application is the patent application to NCR Corporation. It is a multithreaded & web-based application. It works as a mediator between users and internal application and it establishes the secure socket connection with internal applications.

It is a Complete Solution for Indian Railway Board. There is hardware component called DATA LOGGER. DL is DSP (Digital Signal Processor DSP- MC56F8356) based Hardware Component, which contains the information of Railways (Like Trains Status, Track Status, Station Activities etc.) and all this information managed by Application Software called CMU (Central Monitoring Unit). Where CMU receives the data via com-port through a Propriety Protocol which is design by Indian Railway Board and after getting the data the CMU applies some action on raw received data and stores it in Database (InterBase) for future use. The CMU is very user interactive GUI application for the user. User can see the accepted information about the railway stations.

I have done the cloud readiness analysis via Red Hat MTA tool and modernize the C/C++ application. And then transform the C/C++ Workload into Dll/API based solution. All the transformed APIs work as endpoint via C# .Net Core Web APIs. After the successful testing of the Web APIs via Postman, the DevOps operations applied. In DevOps operation the whole process automated and the Docker Image generated. The generated Docker images pushed into the Azure Cloud/AWS Cloud. Hence, we can call the C/C++ APIs from the Web Browser or API Testing done by Postman.

Worked on open-source technologies, where I helped out to the team to make understand the 5G Core (Druid tool), Edge Computing & IoT concepts. And developed Micro-services in Go Language, Created the Docker images and managed Kubernetes into the production environment. I cannot reveal the much internal of the project due to some security reason. Perhaps we can discuss more on this in the interview.

The AppDynamics C++ SDK have been consumed into the TM/TP application to monitor its performance. The AppDynamics is an APM (Application Performance Monitoring) tool. Transport Manager/Planner application is a supply chain management domain, hence there are multiple processes involved to complete a business transaction. The challenge is to track the performance of the module during the IPC. The AppDynamics portal (Controller) shows the lots of features to manage the application performance. gRPC Protocol, another important task, Implemented the gRPC Protocol to remove the CORBA layer from the existing application architecture. The existing application communicates with other the modules via CORBA layer which is RPC module and old technology. The latest version of java does not support CORBA.

NDSUC Application is a lightweight library, which implements NDS Update architecture and can be used to fetch and install updates for NDS maps from TomTom Server (TomTom Dutch company that produces traffic, navigation, and mapping products). The library is implemented in C++ 17, The NDSUC application consumed in .Net application with the help of interoperability. The CodeBase of the NDSU application build by CMake and convert into the COM-DLLs. The NDSUC-Navigation Data Standard update client Application(NDSUC) .

This was a Web application which facilitate the user to communicate with each other via email. It is a one-shot application, owning the following features. My News – Its all yours. Explore the news events, and interests and parts of the world that matter. Add any interest thats important to you. Interests – Customize My News page by choosing from dozens of interests curated by our editors, as well as updates on interests like favourite sports teams, investment news etc. Local News – Pick the place you care about most and stay connected with news from hand-picked local sources.

The Portal Pass is the SSL-Certificate and acts like the entry pass to the customer/employee. The Portal Pass closely works with the NCR-Gateway. NCR-Gateway performs its duty only if the Portal Pass get installed on the Terminal. So, Portal-Pass is a small utility which generate the .pfx certificate and emailed to request user. Then the user must install the requested Portal Pass to access the internal application via NCR-Gateway.

Common Auth is nothing but an application which authenticates the users during login process into the company Portal. The Common Auth works like an SSO (Single Sigh On). SSO means that the user does not require their further credential once the user gets inside NCR-Network. The user can navigate whole Portal & other applications are landing on it without providing user credentials.

The oracle database upgraded from oracle 8 to oracle 11i along with the customization of the database modules. The main challenge was to maintain the customization of the DBs modules. The technologies were used: Oracle, PL/SQL, Java applications, Unix, Business Objects. In the process of the upgradation, Removed the unwanted schemas and carried the normalized DBs modules into upgraded version

The very first CashWorks-CDE is a very huge product which is implemented in US at very large scale. CashWorks-CDE Offers a low-cost financial solution to provide the check-cashing and bill-payment services to the user. The CashWorks-CDE enables the customers to submit any government or their pay roll check and to get the funds in cash or through an ATM card. CDE is set of COM components. The CashWorks hardware communicates with a CashWorks-CDE for information and for the approval/information. CashWorks-CDE receives thr request as an input and redirects it to module, which is responsible for the output. So, it works just as a Mediator between request and Dlls (module).

This is a Desktop IoT based Application, which communications with an Embedded System (A Hardware component consisting of other sub-devices). The Controller handles its sub-devices. The EM Application has a full control to all devices via Controller, the Controller has a capacity to store data comes from EM Application for scheduling the tasks for Hotel Rooms, Hospital and School. This Hardware and Software (EM Application) communicate with each other via serial port using RS-232 protocols and there is another propriety protocol provided by client for Hardware Component how the EM Application and Controller will do communicate with each other.

Data Analyser is an application which is used to interact with the hardware devices via USB Port. There is a hardware which helps to the devices to connect to the computer is known as the USB Board. These devices monitor the room temperature, Humidity, Lights, rotating hardware. The communication looks like (Devices USB Board Controller USB Data Analyser). The devices frequently send the signals to the USB Board and the USB Board transfer the input to USB Data Analyser Application. The data of the devices shared among the countries via web sockets.
