I build secure digital systems, developer tools, and research-driven technology solutions.
I am a software engineer and cybersecurity researcher focused on secure application architecture, real-world digital products, and developer tooling. My work spans production systems, Python libraries, and published research in blockchain, cybersecurity, and digital twin security.
About
I am a software engineer with a strong focus on cybersecurity and secure system design. I build reliable, scalable applications that prioritise data integrity, privacy, and performance.
My work combines practical engineering with research, particularly in blockchain-enabled digital twin systems, where I explore trust, security, resilience, and secure data architectures through both academic publications and real-world software development.

Featured Projects
People-Card
A secure care management system with QR-based access, activity logs, rota management, incident tracking, and audit trails. Designed for real-world healthcare and workforce environments.
Problem solved: Care operations often rely on manual logging and fragmented records, making auditability, accountability, and secure access more difficult.
Security features: Role-based access control, secure authentication, audit logs, protected routes, and QR-based workflow access.
Tech: PHP, MySQL, JavaScript
Role: Sole designer and developer
Impact: Built and deployed as a live system for secure care logging, staff workflow management, and audit-friendly operations.
collide-circle (PyPI)
A Python package for circle-based collision detection in Pygame, created to simplify collision logic for developers building 2D games and simulations.
Problem solved: Collision handling in 2D Python games can be repetitive and error-prone, especially for developers implementing custom circle-based interactions.
Technical contribution: Published as a reusable Python package to make collision logic easier to integrate into Pygame projects and developer workflows.
Tech: Python, PyPI, Pygame
Role: Package author and maintainer
Impact: Published as a public Python package to support reusable collision handling in Pygame development workflows.
care-log-utils (PyPI)
A professional Python toolkit for care systems, rota management, shift detection, and healthcare workflow utilities. Designed to support care providers, rota systems, and healthcare platforms with reusable operational logic.
Problem solved: Care management systems often require repeated custom logic for visit timing, shift-slot detection, and rota calculations, which leads to duplicated effort and inconsistent workflows.
Technical contribution: Published as a reusable Python package providing shift detection, visit duration calculation, and care workflow utilities for developers building healthcare and care-management systems.
Tech: Python, PyPI, Healthcare Systems, Developer Tools
Role: Package author and maintainer
Impact: Released as a public Python package supporting reusable care operations logic for rota systems, visit tracking, and healthcare workflow automation.
pyconstlock (PyPI)
A lightweight Python package for creating constant-style values that cannot be reassigned or deleted, inspired by the absence of a native const keyword in Python.
Problem solved: Python allows variables to be reassigned even when developers intend them to behave like constants, which can cause accidental configuration changes in applications.
Technical contribution: Published as a reusable Python package that provides a protected constant object with reassignment prevention, deletion protection, and uppercase naming enforcement.
Tech: Python, PyPI, Developer Tools
Role: Package author and maintainer
Impact: Released as a public Python package supporting safer constant-style configuration in Python projects.
pymentorbot (PyPI)
A beginner-friendly Python learning assistant package that explains Python keywords, built-in functions, common errors, and core programming concepts with simple examples and CLI support.
Problem solved: Python beginners often struggle to understand keywords, errors, and programming concepts quickly without reading long documentation.
Technical contribution: Published as a reusable Python package with explanations for Python keywords, built-ins, common errors, search/list commands, quiz mode, and friendly fallback messages.
Tech: Python, PyPI, CLI, Developer Tools, Education
Role: Package author and maintainer
Impact: Released as a public Python learning tool to support beginners, students, and developers who need quick Python explanations from the terminal or Python code.
world-data-austine (PyPI)
A Python package that provides structured world reference data for developers, including countries, capitals, cities, currencies, languages, continents, animals, fruits, and colors.
Problem solved: Global and country-related data is often gathered manually from multiple sources, which is repetitive and inefficient for developers building educational, utility, or data-driven applications.
Technical contribution: Published as a reusable Python package to provide easy programmatic access to curated world datasets.
Tech: Python, PyPI
Role: Package author and maintainer
Impact: Published as a public Python package supporting reusable access to structured world data in Python workflows.
morsekit (PyPI)
A Python package for encoding and decoding Morse code, designed to simplify text conversion workflows for developers, educational tools, and lightweight applications.
Problem solved: Morse code conversion is often repeatedly implemented in small scripts and learning projects, leading to duplicated effort and inconsistent implementations.
Technical contribution: Published as a reusable Python package to provide a simple and standardised interface for Morse code encoding and decoding.
Tech: Python, PyPI
Role: Package author and maintainer
Impact: Released as a public Python package contributing reusable functionality to the Python developer ecosystem.

Research & Expertise
My research and engineering work focus on cybersecurity, blockchain, secure digital systems, and digital twin security. I am particularly interested in how trustworthy architectures can improve resilience, integrity, and accountability in modern software systems.
Through my PhD and publications, I have explored blockchain consensus security, cybersecurity performance measurement, and trust frameworks for digital twin management. Alongside research, I apply these ideas in practical software systems and public technical contributions.
