Product – Z/os Web Enablement Toolkit

Applications running in traditional z/OS environments can play the client role of a RESTful web application

and initiate a request to a web server residing on z/OS or any other platform that supports web applications.

The z/OS client web enablement toolkit provides the following components to enable these applications to

more easily participate in the client/server realm:

 A z/OS JSON parser to parse JSON text coming from any source, build new JSON, or add to existing JSON

text, as described in The z/OS JSON parser

 A z/OS HTTP/HTTPS protocol enabler that uses interfaces similar to other industry-standard APIs, as

described in The z/OS HTTP/HTTPS protocol enabler

While the primary focus of the toolkit is to enable traditional z/OS programs running in environmentswhere these types of services are not as readily available (as compared to a z/OS UNIX or Java™ Virtual

Machine (JVM) environment), the services can be run from virtually any environment on a z/OS system.

Programs running as a batch job, as a started procedure, or running in almost any address space on a z/OS

system can usethe toolkit APIs in a similar manner to any standard z/OS APIs provided by the operating

system. Furthermore, programs can invoke these APIs in the programming language of choice; the toolkit

fully supports C/C++, COBOL, PL/I, REXX and high-level assembler languages.

 The z/OS JSON parser

The JSON parser portion of the z/OS client web enablement toolkit provides a generic, native z/OS

JavaScript Object Notation (JSON) parser for z/OS applications.

 The z/OS HTTP/HTTPS protocol enabler

The HTTP/HTTPS protocol enabler portion of the z/OS client web enablement toolkit allows z/OS

applications running in traditional environments to more easily participate as a web services client

application.

Responsibilities:

• Worked on Z/os 3.2 release to work on implement JSON 64 bit parsing

• Worked on APARS related to HTTP component issues

• Created PTF’s to provide bug fixes for Z/os 2.5 & Z/os 3.1

• AS ownership of product belongs to us, were part of creating goals setting and z/OS 3.3

release planning and features.

• Took responsibility for end to end Product lifecycle as Product Owners.

Project: ARK (Mortgage Core Serving)

Description: Project ARK is microservice development and maintenance in COBOL as backend and

frontend calling through API for Mortgages in Santander UK. SANMF is a Legacy Mortgages

system built by Sapiens software with screens, terminals and business specific applicationwhere data is available and to integrate mainframe data with systems like Parthenon (core

banking) and other internal applications, Project Ark builds APIs on request for features like

Payments Holidays, Redemption details, Account Warnings, etc. and to allow these downstream

systems to access this data in a structured and controlled manner on subscription basis from an API

marketplace managed by ARK.

Responsibilities:

• Worked on building services like Account Warnings, where data is not static from ANMF tables

but is dynamic from screens.

• Took the end-to-end Technical analysis and helped business to build documentation about the

systems to delivered few complex features such as Mortgage Account Enquiry, Historic

Redemption Calculations, Dossier Note Update, Arrears Multiplier History, and Payment

Arrangements Service and so on.

• Worked along with Sapiens team and quickly understand their software and their methodologies

which helped our team very well to decode issues without approaching the team more often.

• Perform Development and unit testing of COBOL codes and document the test results.

• Correcting codes and fixing the code issues for the microservices.

• Building endpoints and testing of microservices through JSON front ends.

• Doing enhancements of codes and writing codes and jobs from scratch.

• Worked on design documents.

• Analyzing the code and doing data setup for the Services.

• Perform Performance tests.

• Bug fixes for Production bugs.

• Promoting codes to IST/UAT regions.

• Provide support during IST/Performance testing through Mainview.

• Providing support during prod deployment.

Project: Faster Payments

Description: Project faster payments refer to a type of payment that delivers funds to the payee in real-time or near real-time, typically within seconds or minutes, as opposed to traditional payment methods like BACS that can take several days. These systems are often supported by faster payment schemes and systems (FPS), and are available 24/7 in most supported payment systems.

Responsibilities:

• Worked on Go Anywhere project with MasterCard to reduce the faster payments time by 4 times.
• Worked extensively on Faster Payment schemes and rational database to carry each transaction between the FP scheme and two endpoints.
• Worked on automating the project to run autonomously on scheduler.
• Schedule the jobs for the Payments and create the reports according to the outcomes.

• Project MOSES is a migration project in which we convert the PL1 codes to develop COBOL code for mortgages application. SANMF is a Legacy Mainframe system built by Sapiens software in Mainframe and so as to move the system to a more advanced platform to support modern needs Project Moses was formed. It's a three step migration progress from Mainframe to Linux Followed by AWS.
• In first phase the PL1 programs were migrated to COBOL within Mainframe, our responsibility is to fix the bugs in program with rigorous testing and deploy in batches to Production.
• Understood the complete SANMF business as we have involved in every possible area to migrate the codes.
• Took complete research on After Image Logging tool that capture the Database changes to seamlessly automate the Update programs and automated it to compare the before and after DB changes.
• In Second Phase from Mainframe to Linux, learnt Linux environment and successfully setup a template to test in both the environments.
• Doing enhancements of codes and writing codes and jobs from scratch.
• Worked on Unix for COBOL to Micro Focus COBOL migration.
• Worked with Oracle DB for COBOL to Micro Focus COBOL migration.
• Perform unit testing of the converted COBOL codes and document the test results.
• Correcting codes and fixing the code issues.
• Worked on design documents.
• Analyzing the code and doing data setup for the jobs.
• Raise defects for the failing codes in JIRA.
• Promoting codes to IST/UAT regions.
• Provide support during IST testing.
• Providing support during prod deployment.
