Experience

Beamo | 3i Project

https://www.beamo.ai/
Beamo products virtually teleport users to hard-to-reach places and provide an accurate, contextual, and immersive digital replica of their sites. They capture a 360° view of facilities and create their immersive digital twins in minutes. Users can unify their remote teams under one intuitive platform to support the whole lifecycle of their facilities. As a back-end engineer on this project, I developed a permission management module for hierarchical resources, a file system abstraction layer that allows seamless execution on the cloud and on-premise storage services, and more.

Pivo | 3i Project

https://pivo.ai/
Pivo pod allows solo creators, athletes, equestrians, and realtors to capture high-quality videos and images with 360° motion tracking, target exposure, and auto-zoom powered by AI technology. It is compatible with iOS and Android smartphones. As a back-end engineer on this project, I developed the core API modules and several AWS Lambda functions to offload intensive graphics computations and content metadata generation. I also integrated third-party eCommerce platforms, such as Shopify.
