Freelancer profile translated to English.

Description

My name is Alex Oyono and I am a Data Analyst. I had the opportunity to work at GRDF where I participated in the development of data analysis solutions and dashboards to support teams in their decision-making.

I mainly work on Business Intelligence and reporting projects. I particularly enjoy understanding business needs in order to design useful, easy-to-use solutions adapted to users.

I have had the opportunity to work with many tools such as Power BI, SAP BusinessObjects Web Intelligence, SQL, and Python. Depending on the projects, I am involved in data preparation, data modeling, creating interactive dashboards, and automating certain tasks.

Today, I also want to develop solutions integrating Artificial Intelligence to further automate processes and better leverage data.

Project at GRDF:

• SAP Business Objects Web Intelligence, to design reports allowing managers to track the progress of operations carried out by intervention teams.

• Power BI, in the context of developing a dashboard dedicated to monitoring the surveillance status of pipelines.

This project was carried out in several stages:

•Data preparation

•Data modeling

•Visualization design

•Automation of updates, by connecting to data on SharePoint and integrating Power Query, thus ensuring up-to-date data.
