• Designed and developed web services and web based flow of payments, refunds, voids, authorization and settlements using JEE, spring framework, AngularJS/Bootstrap, Microsoft IIS/.NET and MSSQL as database. Used caching libraries (EHCache & JCS cache) for caching configuration information at startup.
• Developed innovative, award winning module using AWS Lambda to pay bills using Amazon Echo device.
• Pioneered continuous deployment implementation of legacy and Greenfield SaaS application suite components on JBoss EAP 6.4.7 server and WebLogic 10.
• Designed and prototyped, payment processing using EMV Chip cards and its interaction with the card readers using non-blocking TCP/IP socket IO.
• Implemented batch processing module using spring batch, spring integration, Quartz Scheduler to process payment refund files soon as they are received from SFTP server.

Principal Software Engineer

Responsibilities:

• EB and EE were designed and developed using spring framework and JEE technologies to facilitate online banking services, payment origination, processing and auto enroll end customers.
• Technical Lead for design of SOA based solution using web services for enrollments. Proposed and implemented the idea of leveraging legacy module which decreased the development, QA cost by 15%.
• Prototyped and designed cipher security modules for data encryption, XML over HTTP and SOAP web services interfaces including WSDL, type definition Schema (XSD) and custom bindings.
• Designed and implemented session management, single sign on (SSO) capabilities from bank portals to EB and allowing EB to SSO into third party Bill Pay plug-in like Metavante, CheckFree.
• Led the effort to analyze business and technical requirements, estimations, risk identifications, high level design and release management. Elaborated design, use cases, deployment diagrams using UML.
• Conducted design presentation for development, testing solutions, customers and senior management to keep them informed about the technical details, progress and project roadmap.
• Re-engineered module for byte streaming large online bank statements to browser adobe plug-in using IBM GPFS and SAN server capability. This implementation allowed the streaming of online statements size to jump from 2MB to 200MB.
• Architected and designed wire and ACH transaction risk management to avoid fraud by providing asynchronous interface to third party risk management system using IBM MQ, MDB and EJB Timer.
• Spearheaded the effort to analyze critical online banking security fixes (XSS, SQL Injection, CSRF) using Klockwork scans and implementing the fixes.
