Citi Bank, Irving TX (Remote) via Iris Software Jul 2021 – Mar 2022

Lead UI Developer

Project: CFast (Balance sheet Comparison Application

CFast Application was a financial analytics tool designed to compare current, historical, and future balance sheet data. It handled large, complex data sets organized in a hierarchical structure, covering multiple regions and lines of business.

One of the main challenges was dealing with the sheer volume and depth of the data. It required advanced filtering and data processing to help users focus on the specific details they needed. The application also needed to display this complexity in a clean and user-friendly way.

Designing the UI was a key part of the project. We aimed to make the interface intuitive so users could explore complex financial information easily. Features like interactive dashboards, smart filters, and drill-down reports helped users make sense of the data quickly and clearly.

Roles and Responsibilities:

Lead the front-end UI development designed and implemented UI project in latest Angular 14/12, Material Desing RxJs, NgRx, SonarQube, Jasmine and Karma.

Wells Fargo, Charlotte, NC Jan 2019 – Jun 2021

Full Stack .Net Developer

Project: CARA (Compliance Aggregative Risk Assessment)

Description:

I worked on the "eCara" project for Wells Fargo, which replaced an old, slow system that used Excel for tracking risks.

The main goal was to build a new system that could show around 4,000 linked risk items in a clear, tree-like structure. These risks were grouped by business, type of risk, and rules.

Each risk item had three parts: starting risk, how well controls worked, and the remaining risk. Our system had two ways to calculate these risks:

oInitial Calculation: It took basic risk numbers and calculated them all the way up to the company level.

oLive Calculation: If someone changed a risk number, the system instantly updated all other affected risks in the entire tree.

oMaking this complex, flexible "risk tree" look good and work well on the screen was a big challenge, so I built a special component for it using Angular. The system also needed to handle about 300 different user groups, so we made a flexible way to control who could see and do what.

Responsibilities & Achievements:

Architect and design the application from the beginning both front end and back end.

Developed responsive and secure user interface using Angular 10 with Angular Material and back-end .NET Core Web APIs.

Built robust error handling, authentication, and authorization mechanisms using encrypted sessions.

Created Database objects, Indexes, stored procedures, and complex joints and optimized SQL queries in MS SQL Server ensuring high performance and data integrity.

Implemented data extraction, transformation (ETL), and loading workflows using SSIS to integrate data from multiple sources (e.g., flat files, SQL databases), with logging, error handling, and scheduled execution to support reporting and analytics needs.

Set up and maintained CI/CD pipelines using Jenkins, integrated with Git for source control and JFrog Artifactory for artifact management, ensuring automated, reliable deployments using UCD.

Performed unit testing and code quality validation using Jasmine, Karma, protractor, TSLint and MS Test.

Code Review and code optimization.

Maintained ~80% min code coverage for each new and existing change .

Developed reusable and instable Angular Hierarchy Tree Grid component and Idle timeout library.

Utilized standalone components and pipes in Angular to simplify module structure and improve tree-shakability and load performance.

Develop customizable cache for caching API data which has significantly improved app performance.

Maintaining project up to the latest version of angular and other libraries.

Environment: Angular 10.0, Angular Material, RxJS, type script, Asp.Net Web API, RESTful Services, MS SQL Server, GIT, Jenkins, j-frog antifactory, Jesmine & Karma, UDC.
