Network & Security

My networking practice focuses on device configuration, connectivity troubleshooting, secure access, and traffic analysis. I use Packet Tracer and Wireshark to explore how devices communicate, follow packet flows, and investigate common network faults.

This includes working through IP addressing, subnetting, switching, routing, VLANs, and access control concepts. I connect these tasks with infrastructure security fundamentals, paying attention to network segmentation, management access, and clear configuration documentation.

Data Science & ML

I develop machine learning workflows that turn prepared data into predictions that can be evaluated and explained. My work covers exploratory analysis, feature engineering, supervised learning, cross-validation, hyperparameter tuning, and class imbalance handling using Python and scikit-learn.

Projects include student dropout risk, customer churn, and service-level breach prediction. I assess classification performance alongside probability calibration, use SHAP to explain model outputs, and present results through dashboards that help users understand risk and consider appropriate actions.

Analytics & Databases

I work with Python, SQL, Excel, and Power BI to clean datasets, explore patterns, and communicate findings through charts and reports. This involves checking missing values, inconsistent records, and data types before selecting measures that answer the question being investigated.

Database work includes defining tables and relationships, writing queries, and organising information for application features and reporting. I consider validation, indexing, access permissions, and traceable records so that data can be retrieved efficiently and interpreted consistently.

Web Development

I develop database-backed web applications using PHP, Flask, JavaScript, and Bootstrap, connecting user interfaces with application logic and stored data. My projects include prediction tools, role-based dashboards, file uploads, search and filtering, and downloadable reports.

I focus on responsive layouts, clear forms, and practical workflows for different users. Authentication, input validation, parameterised database queries, and activity logging are considered alongside interface design, helping each application support everyday tasks with clear feedback.
