Work Experience Overview
This role focused on implementing comprehensive software testing methodologies to ensure product reliability and compliance with requirements. Working within a specialised quality assurance team, I developed and executed test strategies for complex e-commerce systems with particular emphasis on discount calculation logic and payment processing validation.
As part of the Software Testing Team at King's College London, I was responsible for designing and implementing testing frameworks for a sophisticated shopping cart system. This project-based position involved working in a structured testing environment with an emphasis on systematic fault identification and comprehensive test coverage.
