Anthony Poon.

I designed technology, planned and organized studies, conducted mixed-methods data collection and analysis, and published and presented research in journals and conferences. I worked with faculty in the Departments of Information Science and Global Development.

• Co-designed, created, and evaluated a virtual peer support platform with home care workers in New York City, leveraging participatory design and ethnographic research. Resulted in more community connectedness and empowerment among an isolated workforce.
• Developed and deployed a SMS and WhatsApp-based exam preparation tool for secondary school students in Cameroon in collaboration with local educators and NGOs and evaluated it with statistical and focus group methods. The study aid increased student engagement, encouraged collaborative studying, and helped students identify their knowledge strengths and weaknesses.

I designed and built highly available and secure software services and web applications in the Global Payments Platform.

• Engineered and maintained high-volume payments software services that securely processed millions of transactions per hour with dozens of global digital payment platforms partners. This enabled expansion to multiple international markets (e.g.: India, Brazil, Spain, etc.), introduction of new payment methods (e.g.: electronic bank transfers, mobile payment, etc.), and reduced payment processing costs (e.g.: debit card processing).
• Architected an enterprise system bus that provided interoperability between multiple partner APIs using a shared data model. Designed a pluggable architecture for this platform so that independent teams could integrate with new partners without direct access to sensitive customer data.
• Implemented a web widget service that standardized customer checkout and payment method management across platforms. This unified the user experience and code base across Amazon websites and apps.
• Built and implemented internal tools, including data dashboards, operations management tools, integration testing mocking services, data serialization libraries, and others.
• Mentored junior developers, encouraged design review processes, software development best practices, and supported the needs of peers.

I wrote software, conducted testing and data collection in the field, and published research.

• Created a graphical interface for browsing and summarizing large and diverse data sets including GPS traces, photographs, audio, and ML-annotated activities.
• Gathered data and field-tested a mobile system for capturing state and context of soldiers using the ASSIST tracking device.
