Experience

  • NYSE Equity Market Real-time Data Service App

    This is a mission-critical equity and fixed-income service Salesforce app used by floor traders, investment bank clients, internal electronic traders, and customer support center staff.

    Spearheaded the rigorous business requirement gathering process through brainstorm sessions with internal and external trading partners. I created a technical design document that spelled out the out-of-the-box functionality configurations, as well as custom LWC components and Apex classes. During the implementation phase, I coded nightly and near-real-time Apex batch jobs for data synchronization with external systems. On the front end, I developed Lightning Web Components with Salesforce Lightning Design System CSS styling.

    The app went through stringent QA testing and performance benchmarking. After that, a series of user acceptance tests were carried out with our primary business stakeholders. The project was completed on time, within budget, and exceeding the client's expectations.

  • CPQ Sales Pipeline Salesforce Project with NYSE

    I worked on declarative tasks, including data modeling, flows, and validation rules. My main job was on Apex, SOQL, SOSL, LWC (JavaScript ES6+), and Salesforce Lightning Design System CSS. I acted as a hands-on and heavy-duty Salesforce developer and architect for CPQ, Community Cloud, Marketing Cloud, Sales Cloud, and Service Cloud.
