Who I Am

Summary

Full-stack software engineer with 3.5 years of commercial experience delivering 8+ production platforms following Agile principles. I build with TypeScript, React, NestJS, PHP/Laravel, PostgreSQL, MySQL, and AWS — owning features end-to-end from database schema to deployed UI.

My work spans CRM platforms, warehouse management systems, pricing tools, supplier portals, and internal tooling. I contribute across the full delivery lifecycle including CI/CD pipelines, Grafana observability, infrastructure automation with Ansible, and serverless architecture on AWS.

Full-stack software engineer with 3.5 years of commercial experience delivering 8+ production platforms following Agile principles, using TypeScript, React, NestJS, PHP/Laravel, PostgreSQL, MySQL, and AWS. Owns features end-to-end from database schema to deployed UI, including serverless architecture (AWS Lambda), infrastructure automation (Ansible, Docker), CI/CD pipelines, and observability (Grafana, Sentry). BSc Computing Science with First Class Honours from the University of Glasgow.

Capabilities

How I Can Contribute

Turn operational and commercial workflows into clear, maintainable software. Comfortable with ambiguous requirements, iterative delivery, and cross-functional feedback.

Build responsive, data-rich interfaces with reusable components, predictable state/data fetching, accessible markup, and test coverage where it protects behaviour.

Design and implement APIs, service boundaries, validation, database-backed workflows, integrations, and migration-safe changes across modern and legacy systems.

Build and maintain CI/CD pipelines (Bitbucket Pipelines, GitLab CI), Docker-based environments, Ansible-provisioned servers, AWS Lambda deployments, Grafana dashboards, and Sentry error tracking across all production systems.

Use tests, static analysis, code review, refactoring, and clear abstractions to make systems safer to change without introducing unnecessary process.

Create focused tools and scripts that reduce manual work, connect systems, and make repeated engineering or operational tasks easier to execute.

Use AI coding tools like Claude Code, Codex, and Gemini as part of daily development workflows for code generation, review, debugging, testing, and architecture planning. Integrate Claude and OpenAI APIs into production applications.

ABSMS: Automated Bash Script Marking System

Honours Dissertation · University of Glasgow · 2024

92.5
SUS Score
Top 10%

Designed and developed a full-stack web platform for automated marking of UNIX/Bash scripts in an educational setting. The system provides role-based access for students and markers, handles assignment creation and submission management, and automatically grades Bash scripts by executing uploaded test files against submissions.

Students receive formative feedback on their first submission and summative feedback on their second, with the option to request manual re-marking. The platform was evaluated through automated testing and a user study that produced a System Usability Score of 92.5, ranking in the top 10% of all SUS scores.
