  Dec 2021 - Sept 2022

  I worked in QA testing for Comcast's Xfinity Mobile doing manual API testing. I started my journey in software development in 2019 after finally deciding to take the plunge and learn how to code. Early in my coding journey I realized this is what I wanted to dedicate myself to and love every aspect of it. Learning new things is my passion and there is always something to learn in this great field.

  As a specialist in triaging production-level systems architecture for Comcast's Xfinity Mobile, I excel in data analysis, data visualization, data engineering, and the development of machine learning models to uncover patterns and derive actionable insights. I successfully designed and developed the backend server for an AI assistant application, which processes user queries by searching proprietary company data sources, retrieving relevant information, analyzing and summarizing the data, and formulating precise responses. This system leverages a Retrieval-Augmented Generation (RAG) architecture, implemented in Python, and incorporates advanced libraries such as LlamaIndex, LangChain, and OpenAI's Chat & Embedding APIs.
