Hi, I'm Onome Alexandra Dedekimor 👋

A Data Analyst and Problem Solver · turning raw data into clear, actionable business insights.

About Me

I'm building a career in Data Analysis — with a background that might surprise you.

Five years of Chemical Engineering trained me to think in systems: how do things work, analyze experimental data, find where inefficiencies and inconsistencies lie and document solutions clearly. I now apply that exact rigorous thinking to my data analysis skills.

With certifications in Data Analysis from AltSchool Africa and the Google Data Analytics Professional Certificate (in progress), I combine technical tooling (Python, SQL, Advanced Excel, and Power BI) with strong stakeholder communication to drive data-informed decisions.


🔧 What I'm Currently Working On

  • Dashboards — building interactive Excel and Power BI dashboards to track sales performance and operational KPIs
  • SQL for Data Cleaning — writing clean queries and scripts to investigate, clean and validate datasets
  • My Portfolio — organizing end-to-end data analysis projects showing exploratory data analysis (EDA) and visualization
