Cognizant Technology Solutions as Solution Architect Jul ’14-Till Date
Key Accomplishments
Played the role of Solution Architect/Stream Owner for Payment Platform APAC region for JPMC APAC. This project was bleeding with stability issues and solution involved identifying Anti-Patterns of Stability and mitigating the same. Architecture safety patterns like Circuit Breaker, Bulk Heads and Time Outs were used for developing the solution. This solution helped the client in achieving predictive monitoring of application and quick resilience
Played the role of Solution Architect for payment domain projects like CPRS Strategic Cheque Solution, Commercial Banking Online, Host-2-Host, Faster Payment Service and Client Money projects for Lloyds Bank Group UK. This project also involved the IFCH, which is a Polaris product, to be integrated with multiple channels and products. The solution was responsible to automate certain manual operations
Played the role of Application Architect for Common Wealth Bank of Australia/Sydney. Created the End to End payment domain solution for Low Value Settlement System using Open Payment framework (OPF) of Clear2Pay. Travelled to Sydney (onsite) for creating the Solution Architecture document. This solution automated the payment processing of low value settlements which was RBA mandate
Played the role of Application Architect for Bank Payment Hub (BPH) CBA. This payment hub was like one stop shop for all types of payments and all payment transactions were processed using the hub. It was used to process the Proprietary cards, Scheme Debit, IMT/RTGS, SWIFT sanctions, General Ledger, Payment Journal, etc. C2P OPF was used to build this Payment Hub. This solution solved the integration hair ball problem
Played the role of Solution Architect for my brainchild product called FTPSLP/MetaFTP which is a data integration/migration product which is used or installed in Chase bank USA
Created and conceived a payment product called Channel Integrator which integrates the SFTP clients with the back-end payment engine. The product can push and pull payment messages and payment responses. This is part of Digital transformation initiatives
Created cost effective solutions for clients using stateless applications that can easily shed the inertia for scaling. Used JWT token authentication for protecting the REST services which leverages the stateless sessions.
Used open source solution for securing emails using public key cryptography which is a low cost and flexible solution for the same
Leveraged few light weight solutions for batch application problem domain using spring batch and task executor
Created the web portal solution that is a composite application that integrates three BI tools to produce a dashboard of consolidated view in one screen. This is one stop shop solution
Created a brainchild product called FTPSLP which uses FTP/SFTP to integrate FTP clients and also pushes the data into remote gateway which can be a message oriented middleware. Hold the patent for this product.
Helped the client automate certain manual cheque processing and payments associated with it using the integration with payment transaction hub. This has helped the client to reduce cost and infrastructure.
Used seamless integration designs to reduce cost of maintenance. Moved away from P2P integration into bus architecture model
Built concurrency model solutions using optimistic locking when multiple users retrieve the same record and update the same in the database, the version no is used to resolve the concurrency model problem.
Provided security solution using SITEMINDER doing the pre-authentication in the ORCA project
Provided security solution using Oracle OAS and OES doing the pre-authentication in the command centre project
Created Transaction model for local and global transactions and tuned the model for performance
Created the caching solution using WAS dyna cache out of the box feature for ORCA project
Created a CIRCUIT BREAKER solution to protect the system from cascading failures and resource exhaustion
Created the email solution using task scheduler which is deployed in the WAS cluster with four nodes and only one node would send the email. This model uses the optimistic locking on the database to enforce concurrency
Created the solution using asynchronous method execution and task scheduler combination to capture metrics for the ORCA web service
Proposed and architected a pharmacy intake platform which accepts various kinds of documents from various channels, identifies the key attributes and forwards it to correct users to be triaged and processed. Delivering enhanced time to market and lower turnaround time coupled with cost savings. Implemented in Microservices and PEGA.
TCS as a Technical Architect Jul ’13-Jul ’14
Key Accomplishments
Created the Smart cache push solution where the database would push the changes to the tables to the front end using the Oracle AQ and JMS listener. This solution was innovative and cost effective
Applied Performance optimization to the application using open source caching of DB calls
Optimizing the memory and code footprint to enhance the TPS of the application
Loose coupled solutions for low cost of maintenance. The cost of applying the change should not be high
Created solution for Global transaction using Atomikos and XA datasource
Developed Hibernate Performance Tuning Guide
Recommended the solution approach for scalability and horizontal scaling for achieving 40,000 users and 800 concurrent users
Recommended solution in multiple database transaction management.
Provided Apache directMemory Soluion for performance uplift
Provided and implemented browser cacheing using cacheFilter
Recommended Exception Handling Strategy to team and project
Provided zero garbage and Object pooling solution for reducing GC time as
oPerformance enhancement. Used JConsole to find the profiling
HCL as a Technical Architect Mar ’11-Jun ’13

Payment solutions were extended to digital channels using the channel integrator product which integrates the mobile, tablet and desktop. This is part of Digital transformation initiatives
Created the End to end payment solution for low value settlement system using open payment framework using OPF from c2p
Played the role of integration architect for L3A payment platform. Creating interface designs for integration from payment to other downstream systems
Achieved scalability from 70 TPS to 200 TPS for the payment hub during the holiday season
Performance benchmarking to figure out the best method for application orchestration was done, the following methods were used
oBPEL(long running) orchestration
oBPEL micro flow orchestration
oJava orchestration using SCA
oPlain Java orchestration using JAX-WS.
Empirical data was gathered and analysed. The results of the empirical data was shared with customer
Payment solution can seamlessly integrate with different downstream flavours using spring integration. This circumvented the silo based architecture
