Experience
Belkin Wemo IoT Platform
https://aws.amazon.com/solutions/case-studies/belkin-case-study/An IoT platform to support the entire Belkin Wemo line of home electronics, including connectivity management, secure authentication, and command and control.
I created a new IoT architecture centered around AWS IoT Core and collaborated with a team of developers to migrate their monolithic Java application to an event-based architecture using MQTT as the primary communication protocol between client devices and servers. I also provided architectural guidance to the internal hardware team and security operations center (SOC) vendor to migrate the Wemo Smart Plug from running Linux on a Cortex CPU-based device to running FreeRTOS on a more cost-efficient microcontroller. Both initiatives achieved a 30% reduction in operational costs, improved user experience by reducing command and control round trip time in half, and reduced the development time of new features in half.

Deckers Brands
https://www.youtube.com/watch?v=4Y3ddj06OOs&t=30m54sA modern microservices application platform that supports Decker Brands' direct-to-consumer eCommerce applications.
I designed the cloud architecture to modernize their omnichannel application platform, which included critical eCommerce services, from a monolithic architecture based on .NET Framework on Microsoft Windows Servers to a microservices architecture running .NET Core on Linux-based ECS containers or Lambda on AWS. It allowed Deckers to scale their platform during peak sales events and improve their customer experience by setting up regional services to reduce latency and risk and improve service availability.

Foot Traffic Forecast for Retail Stores
A time-series forecasting solution to predict retail foot traffic.
I was the technical lead for the project with one data scientist from the partner and one data engineer from the customer to develop a solution to predict the foot traffic of retail stores in the United States with a p95 error smaller than 10%. I developed the solution with the DeepAR algorithm on Amazon SageMaker using data from hardware sensors at retail locations.

Chatbot for Reordering Office Supplies
A text and audio chatbot to reorder standard office supplies.
I designed and created a chatbot that could receive phone calls or Slack messages to allow customers to repeat orders for office supplies. I developed this solution as an independent front end using Amazon Connect to handle incoming phone calls and logic routing, Amazon Lex to provide intent detection and Slack integration, and AWS Lambda functions to process the data and send the API request to the fulfillment service.
