Back to original languageAbout Hamid
As a data enthusiast, I specialize in helping companies leverage their data. My skills cover all stages of data management, from extraction to visualization, including transformation, storage, and analysis.
For data extraction, I implement automated tools to ensure reliable and secure data retrieval. For transformation, I clean data to ensure that interpretations made from it are correct. I also handle storing data in a centralized location, called a data warehouse, to facilitate data access and manipulation.
Then, for visualization, I create dashboards in software such as Tableau Software or Power BI to give company teams easy access to data and quickly answer questions.
With 7 years of experience in this field and a data computer engineering degree, I have had the opportunity to work for clients in various sectors such as banking and the public sector, all facing similar data centralization and exploitation challenges. I now better understand the challenges companies face and am able to effectively advise them to maximize their data utilization.
