Solutions Architect & Software Developer

Greetings, I’m Paul Bradley.

I’m an AWS Solutions Architect and Go Software Developer. I focus on designing & developing software that leverages Lambda technology to deliver cost effective and stable solutions. My daily work project has been featured on the AWS public sector blog : Breaking down patient data silos in UK healthcare with serverless cloud technology.

This is my personal site; therefore, this site’s content is not endorsed by my employer, government, or dog. I work for the national health service as a solutions architect & software developer.

In my spare time I write short stories: standalone tales of 1,000–3,000 words, in genres including science fiction, horror and supernatural. My first collection, se7en is available for download in all the popular ebook formats.
