Physicist and a passionate data analytics professional. Skilled in Excel, Microsoft access, Tableau, power point, power BI, SQL , Python and R programming.My journey in data analytics/science started during my undergraduate research, titled "Deposition and optical characterization of cadmium sulphide quantum dots ", in 2019/2020, where I analyzed over 5,000 entries of data with excel spreadsheet under the supervision of Prof. Mike Osiele. it was found that :✓ All the deposited cadmium surphide quantum dots exhibit the same absorbance spectral.✓ All the deposited cadmium surphide quantum dots absorbance coefficients at different wavelength exhibit similar characteristics.✓ Cadmium surphide quantum dots have maximum absorbance at the ultra Violet region of the electromagnetic spectrum and recommended that:• Locally deposited quantum dots should be used to fabricate solar cells.• Effect of temperature on absorbance spectral should be studied.• Reflection and transmission spectral of CDS quantum dots should be studied.Even before my first data analysis with excel I have been analysing data manually right from my secondary school( Generating data by experiment and visualizing them graphically ) It has been amazing working with data.Specialties;.
