I joined Walmart Global Tech in 2022 to work on Neural Machine Translation. My contributions encompass all fronts of the Data Science lifecyle: data engineering, ML modeling and evaluation, MLOps, and deployment. This has helped me develop an end-to-end mindset when building ML solutions.

I have been involved in two projects: Query Translation and Item Translation – both of them already deployed in production. The first one aims to enable search for Spanish-speakers at walmart.com. By means of Language Detection and Machine Translation, we map Spanish queries to their English equivalent to allow the downstream systems to work transparently. A paper describing our solution is available here.

On the other hand, Item Translation is focused on translating the catalog of one market to one or many target languages. We trained custom translation models and leveraged several services in the Google Cloud Platform to translate to French more than 100M items indexed at walmart.ca. Currently, we are on the way to translate the content of walmart.com to Spanish.

We continue to scale these solutions to handle more translation use cases within the company.
