Harrison Weru

I harness the prowess of R-Programming to automate data pipelines for efficient ETL processes to support EDA.
I am familiar with using the tidyverse package for data manipulation and DBI and database-specific packages to interface with various database systems in the ETL process.

I can manage and query both SQL and NoSQL database management systems efficiently for further analysis, seamless integration of dataset sources, and performance optimization.

I have the ability to detect and correct data entry errors, normalise data, merge and integrate datasets from different sources and perform data preprocessing analysis such as Principal Component Analys (PCA) for dimensionality reduction.
Other data preprocessing analysis I can perform include multidimensional scaling, factor analysis, cluster analysis and others.

I am able to use visually appealing and interactive reports and dashboards to communicate complex data insights to stakeholders in a way that is easier to comprehend.

I can use techniques such as hypothesis testing to identify and understand causes of observed patterns in a dataset.
Other techniques I am familiar with include correlation analysis, descriptive analysis, time series analysis and others.

I am capable of applying statistical models such as Monte Carlo simulations and Regression Modelling to develop machine learning algorithms for predicting future performance.

I have learned and practiced extensively on how to use Git and Github for version control and collaboration on coding projects. This has been very useful to improve my adaptability, teamwork and collaboration skills.

I am proficient in using AWS for scalable data storage and processing. I have previously run R on an Amazon EC2 instance, connected with PostgreSQL on Amazon RDS and stored files including R scripts on Amazon S3.

I have advanced writing skills that enable me to breakdown complex data insights and phenomenon into simple information that any stakeholder can understand with ease. I am capable of writing both technical and nontechnical reports, briefs, and other materials for any audience.
