Building things that actually run.
I'm a final-year BSc (Hons) Software Development student at the University of Stirling, based in Falkirk. I came up through Forth Valley College on an HND (Graded Unit B) before articulating into the honours years, and I'm now in Year 4, the final stretch before graduating in 2027. I'm strongest in Java and Python, comfortable in C++ and C#, and I pick up whatever the problem in front of me needs.
My GitHub is a working logbook: a distributed mutual-exclusion system passing tokens between a controller and three nodes over TCP sockets, an extension to the Triangle language compiler for my CSCU9A5 module, a machine-learning classification project on forest-fire data, Dockerised databases, ethical-hacking coursework, multi-site web scrapers on the Apify platform, and a fair few Java games for when I want to enjoy myself.
I'm looking for an internship or a graduate role where I can keep shipping and keep learning from people better than me. Honest about what I know, fast at picking up what I don't, and genuinely good company on a team.

I'm actively seeking an internship or graduate role. If you're building something interesting, let's talk, the connection's open.
Final-year (Year 4) BSc (Hons) Software Development student at the University of Stirling, on track to graduate in 2027 after completing my HND at Forth Valley College (Graded Unit Grade B). Proficient in Java and Python and experienced in C++ and C#, with honours-level work spanning distributed systems, compiler construction, machine learning and full-stack development. Beyond coursework I ship real projects, from Dockerised web apps to Python and JavaScript scrapers on the Apify platform, and I build and tune my own PCs. Seeking an internship or graduate role to turn this practical, self-directed experience into production software.
Education
BSc (Hons) Software Development, University of Stirling, Scotland
January 2025 to 2027 (expected) · Years 3-4 (Honours) · Currently Year 4 (final year)
Distributed Mutual Exclusion System | Java, TCP Sockets, Swing
Built a token-ring mutual exclusion system in which a controller coordinates critical-section access across three nodes over raw TCP sockets
Designed components for connection handling, mutex logic, message buffering, logging and graceful shutdown to keep concurrency safe and observable
Visualised the running system through a four-panel GUI (one controller and three nodes)
Triangle Language Compiler (CSCU9A5) | Java, Gradle, picocli, TAM
Extended an educational Triangle-to-TAM compiler with new language features, including a loop-while-do control structure, curly-bracket blocks and a "double" (**) operator
Added a constant-folding optimisation pass and an AST statistics visitor that walks the syntax tree to report node counts
Built a professional picocli command-line interface exposing output, AST visualisation, folding and statistics options
Cationary (CatDictionary) | Java, SQL, Docker
Developed a full-stack Java Swing cat-breed dictionary application backed by a SQL database, deployed via a separate Dockerised database container
Engineered a layered architecture: DAO data-access layer, service layer with interfaces/implementations, factory pattern, authentication/login, a quiz feature and admin tools
Authored full software-engineering documentation: functional/non-functional requirements, inception document, project plan and testing logs
Built a Python Apify actor that aggregates job listings from 14+ boards across the UK, US and EU (Reed, Totaljobs, CV-Library, Indeed, Adzuna, GOV.UK and more) into one deduplicated dataset
Implemented salary parsing with currency detection (GBP/USD/EUR), cross-board deduplication and filtering by job type, location and minimum salary
Containerised the actor with Docker for serverless deployment on the Apify platform
