Alex

Hi 👋! I’m Alex - sometimes going by the memorable name of 0x416c6578 online. I’m a backend software engineer working in financial technology (specifically Open Banking payments).

I am currently interested in:

• Scala
• Go

In general, the content on this website and my Github page is created without the aid of LLMs. Whilst I appreciate the power of these tools for generating code - and I do absolutely use them as a learning aid - I believe it a better use of my free time to truly understanding the things I am working on.

As our island of knowledge grows, so does the shore of our ignorance. - John Archibald Wheeler
