Hello World.

With a year of dynamic experience as a Software Engineer at Amazon and two insightful internships at Barclays, I've cultivated a solid foundation in feature development and collaborative dynamics. Through taking ownership of delivery workstreams for global features I have assisted in customer retention, automated service alarming and real-time cloud usage analysis.

Beyond my career, my passion for machine learning and innate curiosity has driven projects such as language-based stock analysis models, hybrid recommender systems, contributions to national curriculums and a published paper that found its way into news, blogs, and radio discussions across Canada, Brazil, the US, and the UK.

Thinking towards my future, my path is now aimed at the crossroads of technology and management. With a balanced experience in owning crucial meetings, rapid prioritisation and technical design I'm excited about the prospect of contributing my skills to higher-level software engineering roles and transitioning into entry-level management positions.

Join me as I navigate these paths and work towards bringing a balanced blend of innovation, customer delight and practicality to my work.

A Practical Deep Learning-Based Acoustic Side Channel Attack on Keyboards

As part of my MEng at Durham University (2018 - 2022), I performed an experiment in which I wanted to see if a deep learning (DL) model built for image recognition could apply it's state-of-the-art architecture to the relatively underexplored problem of keystroke acoustic classification. This paper went on to get some international attention...
