WORK EXPERIENCE

Sr. Android Developer Centific (rebranded from Pactera EDGE)

Redmond, WA since Oct’ 2022

Lighthouse Mobile – Internal App

The Lighthouse application is an application for capturing images of retail shelves, running ML inferencing on them, and displaying to the user a list of suggested actions like replacing missing items or swapping misplaced ones. Features include:

a) A scrollable map screen to aid the user in navigating the store

b) A robust camera, featuring both single and burst capture modes. Until it was moved to the server, the Mobile app was also responsible for stitching together captured images into one single panoramic image using OpenCV.

c) User can view planogram compliance data

Project Summary: I was brought on to build an application for planogram compliance from scratch, as well as mentor a junior developer. As the only dedicated Mobile Developer, it was also part of my duties to be an effective representative for the platform in conversations with UX and business. Most of my time was spent/wasted trying to figure out how to improve image quality for photos taken at a walking pace. Professional photographers don’t use smartphones for a reason.

Responsibilities:

Built an application from scratch following MVVM/Clean architecture patterns

Mentored a junior developer in both Android development and general Agile practices.

Built out a robust camera application using Jetpack CameraX

Added AR product recognition to camera using ONNXruntime and YOLO model.

Worked to ensure image quality during a walking speed capture.

Added support for push notifications through Firebase Cloud Message and later Azure Notification Hub. Responsible for the project’s Firebase console.

Implemented dependency injection using Hilt.

Ensured app was adequately unit tested.

Since there were no QA testers, took on responsibility of testing and ensuring quality of both the mobile application and its backend services

Responsible for delivering mobile and end-to-end demos at the end of every sprint.
