Hello friend, welcome to my LinkedIn!I am Diego Oliveira, I am a brazilian who is seeking challenges everyday to improve my hardskills.I have a bachelor's degree in Telecommunications Engineering, I also have MBA: in Industry 4.0 and in Networking Virtualization. I have a growth mindset and I am self-driven, I often see the problems/difficulties as an opportunity of learning, because of it I love studying and learning at doing (my home is a learning paradise). Data is my greatest passion, I usually develop Data Driven System to provide solutions to generate wealth through data and help the people/company from different perspectives. I have ever worked with data in couples of approaches: health, telecommunications, industry and etc. And I have also been awarded for my projects: development of a BI system to improve public transport of Teresina (AFD - Agence Française de Développment and Teresina City Hall) and Shrimp Farm System 4.0 to improve the production and management of shrimps (USP - University of São Paulo and Claro Brazil). Currently I am a mid-level data analyst and ETL developer in Department of Health of Pernambuco. I feel comfortable but not limited to working with tools like: languages python, R, C, SQL, postegres/MySQL/Oracle, hadoop, spark, airflow, airbyte, DBT, streamlit, power BI, qlik sense, metabase, grafana, and I am also fully motivated/available to learn new ones. So then, this is a little bit about me. I like to connect to people around the world, then if you found me interesting, please, choose one language between Portuguese, English or French to talk and share experiences, or visit my repository at GitHub: https://github.com/diegooliveiradearaujoThanks a lot! ;)
