I use Python for data analysis, modelling, and automation across diverse datasets. My work includes data cleaning and manipulation using pandas and NumPy, exploratory data analysis, and statistical analysis using SciPy and statsmodels. I build analytical and predictive models, visualise results using Matplotlib and Seaborn, and automate analytical workflows with reusable scripts and notebooks. These Python-based solutions enable efficient analysis, reproducible results, and data-driven decision-making.

Python Based Data Analysis

13754911
I perform regression and correlation analysis to identify, quantify, and interpret relationships between variables within complex datasets. My work includes exploratory analysis, correlation assessment, and building regression models such as simple and multiple linear regression, logistic regression, and polynomial regression. I evaluate model assumptions, statistical significance, and goodness-of-fit using appropriate diagnostics and metrics, and interpret coefficients to derive actionable insights. These analyses support hypothesis testing, forecasting, and evidence-based, data-driven decision-making.

Regression and Correlation Analysis

13754916
I use Microsoft Excel for structured data analysis, reporting, and automation within analytical workflows. My work includes advanced use of Pivot-tables, Power Query, and Power Pivot for data cleaning, transformation, and data modelling across multiple sources. I apply advanced formulas such as XLOOKUP, INDEX-MATCH, dynamic array formulas, and conditional logic to perform calculations, validation, and reconciliation. I also build dynamic dashboards using charts, slicers, and data validation, and automate repetitive tasks with VBA where required. These solutions enable accurate analysis, efficient reporting, and data-driven decision-making.

I use R programming for statistical analysis, data manipulation, and advanced analytics across diverse datasets. My work includes data cleaning and transformation using tidy-verse packages, exploratory data analysis, and statistical modelling using regression, classification, and time-series techniques. I apply hypothesis testing and inferential statistics to validate insights, create high-quality visualisations with ggplot2, and build reproducible analytical workflows using scripts and R Markdown. These solutions support robust analysis, clear communication of results, and data-driven decision-making.

R Programming

13766089
I use machine learning techniques to analyse, model, and extract insights from structured and unstructured data. My work includes data preprocessing and feature engineering, training and evaluating models such as linear and logistic regression, decision trees, random forests, gradient boosting, and clustering algorithms, and optimising performance through hyper-parameter tuning and cross-validation. I apply statistical and mathematical foundations to interpret model outputs and assess accuracy, bias, and generalisation using appropriate evaluation metrics. I also build end-to-end ML pipelines for experimentation and deployment, visualise results to communicate findings clearly, and integrate models into analytical workflows to support data-driven decision-making.

Machine Learning

13766091
I use Microsoft Power BI for data modeling, analysis, and interactive reporting across complex datasets. My work includes connecting to multiple data sources, cleaning and transforming data using Power Query, and building optimized data models with proper relationships and calculated columns. I write DAX measures to perform advanced calculations, time-intelligence analysis, and KPI tracking. I design interactive dashboards and reports using visuals, slicers, and filters, ensuring clarity, performance, and usability. These solutions enable stakeholders to explore data independently and support informed, data-driven decision-making.
