Hi, I'm Ingrid Araujo da Silva ✨

Working as a Data Analyst, my focus is on creating strategic solutions through data analysis, continually improving my skills in Microsoft tools. At the same time, I have been expanding my knowledge in Data Science, with an emphasis on Python, SQL and ETL processes, aiming to enhance insights and generate high value for the projects in which I participate.

Tools and technologies that are part of my daily life:

  • Data Analytics Bootcamp Project: Institute Localiza!
  • I'm currently in the last year of my Bachelor's degree in Economics and my TTC will be “AI in the reduction of cognitive biases (Anchoring Bias) in Brazilian consumption", with the support of Python and Machine Learning.
