About Me

I'm a Full Stack Developer. My background is in Theoretical Physics having completed my First Class masters in July 2018. I currently work full-time for Dunelm as a Full Stack Developer developing mainly focusing on payment. Specifically, implementing a new payment method in the backend which is event driven using AWS.

For my role, I work across the full stack, from working on the front end build using React to improve the UX and UI to using AWS Lambda functions, SQS, SNS, DynamoDB and S3 adding backend services.

I’m constantly learning new tools and technologies, currently focusing on UX, UI and using AWS for back end web development.

When I’m not developing, I spend my time traveling. I enjoy experiencing the wide range of cultures the world has to offer. I've also recently enjoyed drone flying.
