PROFESSIONAL EXPERIENCE

WELLS FARGO, Concord, CA July 2017 – November 2022

Lead Software Engineer July 2017 – November 2022

Team Lead for the Dispute Automated Tracking (DAT) and Electronic Form Work (EFW) applications.

DAT is a WF High Risk web-based application to detect and prevent Debit card fraud supporting Fraud Operation and Debit Card Fraud Operation leveraging the WF internal middleware web services and external Visa interfaces. DAT was designed and developed internally employing Spring/MVC, JQuery, JSON, AJAX, technologies, Axis web services, Tibco Workflow, Websphere, Windows servers, and SQLServer.

Leads DAT to migrate to Tomcat from Websphere and upgrading to Spring 5.0 from Spring 2.0.

Served as Team Lead and SME for the following DAT projects: Applet rewrite to Spring/Jquery, Security Remediation to resolve vulnerabilities complying to Wells Fargo, while mentoring team members in India location. Agile is the methodology driving the projects.

Tapped as Team Lead and SME to EFW projects. Leads the rewrite EFW to Spring/Jquery from Java Applet deploying to Google Cloud Platform. The project will be migrating NAS documents/images to KAFKA base subscription, Rest web service, use APIGEE for web services publication, replacing Tibco to Light Weight Workflow and Websphere with Tomcat servers.

Accomplishments, Development and Responsibilities:

Coded the Work tab using Jquery, Javascripts, Spring 1.2, Edge and Java 1.8. I designed and code to integrate the customers call to launch (screen pop) the Work tab from the IVRU. This was very complex and challenging due to multiple business partners from Voice, incoming business channels and System of Record like Savings, Checking and IRA applications.

Coded the login process using the system stack to allow access to DAT as a secondary application guard rail using the profiles stored in Sqlserver. Coded from scratch the Javascripts/Views, Controllers, Models to retrieve user provides and enable certain fields, dropdowns, links, and hovering. Etc. I coded the abstract objects to be used (extended) by other functions and tabs within DAT UI.

I designed and coded the AJAX calls from RPC to retrieve backend data either from DB or web service.

I designed and coded the web service client calls to Visa, an external partner to retrieve all debit cart transactions and disputes and events. It was coded using Axis 1.2 working and defining the rules and fire wall security with Visa development team.

I coded API calls to Tibco cases, queues, priorities events in Java 1.8. API calls were reuse and extended in batch and Microsoft service running 24/7.
