Integrated Smyte and Sift Science into fundraiser management and donation flows, among others, as part of the Trust & Safety platform.Led several platform initiatives, including: integrating Elasticsearch with the fundraiser create and manage flows; performance tuning and load testing for high-volume API calls such as retrieving donation data; and proof-of-concept for event sourcing with Apache Kafka for the fundraiser and donation flows.Supported new feature requests and enhancements for integrations such as WePay, PayPal Classic, Marketo and Smyte.Implemented the Recent Activities page and part of the Supporters page of the Manage Fundraiser 2.0 project using React.

Implemented integrations with various third-party providers, i.e. Smyte (for fraud prevention), Marketo (for marketing collaborations), WePay and PayPal (for processing donations).Updated donation schema to enable tracking payment provider-generated IDs and errors. Implemented audit logging for tracking various fundraiser and donation state changes.Improved server-side error logging and throughput monitoring using Sentry, New Relic and Datadog.Refactored monolithic legacy web project into multiple projects, which allowed the DLLs generated from these projects to be reusable in other solutions, i.e. for creating tools around payment processing and organizer account management.

Led the Enterprise Alerting project to implement hierarchical alerting functionality for the AtHoc Alert application. Worked closely with the product manager on the overall design, including extensible user base management and cross-systems delivery.Led the project to merge the operator and end user management functionalities to create a more cohesive user base domain model, and coordinated with other development streams to manage dependencies of affected entities in other domains within AtHoc Alert.Designed and implemented the mass delivery of text content and multicast audio streams to IP phones through Cisco’s Unified Communications Manager (UCM) APIs, making use of SOAP web services to gather IP phone-related information and WCF REST services to deliver alerts to the targeted IP phones.Designed and implemented the integration piece with Cisco’s Digital Media Suite (DMS) for delivering alerts to registered LCD TV devices, using XML-based APIs to create the necessary artifacts to initiate and terminate the emergency notification alert delivery.Developed the transformation engine using XSLT to create the necessary payloads for the CAP protocol to exchange activation and reporting information with IIM-enabled Giant Voice (GV) devices from different vendors.

Developed software applications for an application with a SaaS (“software-as-a-service”) delivery model servicing the real-estate foreclosure industry. This included defining rule sets and activities for business workflows using .Net 3.0’s Workflow Foundation (WF) technology.

Integral in designing the initial architecture for a major proof-of-concept project, using ASP. NET technology and AJAX components being rendered within a C# Winform application.Developed client-side user interface (UI) in C# Winforms for a rate guideline application, with web services in Java being the focal integration point for data delivery.Selected to lead, design, and implement web services, middle-tier and backend components in Java for a SOA-enabled dual-client pilot project (B2B) with APIs accessed by both web and C# clients; subsequently recognized by US and Hong Kong development teams for outstanding work, dedication, and on-time delivery.Chosen to consult on, train (including material development), and mentor associates in South China office on module handover.Experience in build and release management, having coordinated releases with developers in both Hong Kong and US teams.
