My name is Aldwin. I'm back-end-leaning full-stack (web-) developer with over 13 years of full time professional experience at various software development agencies. Besides that, I have years of hobby-programming and open-source experience, with Fluture[1] being my most well-received.
I've been leading small teams for the last eight years, focusing on developer enabling work such as process management, devops, software architecture, and coaching.
I'm very passionately in particular about functional programming, and I'm hoping to coach teams when it comes to the cross-over between functional programming and software architecture - something a lot of developers who are new to FP struggle with.
Although I have been involved in a huge variety of software types, I'm particularly well-experienced when it comes to real-time, offline-first web-applications and real-time data processing.

Some people's brains just work this way. Here's an example of a somewhat popular and regularly maintained library written in a similar style: https://github.com/enkimute/ganja.js/blob/6e97cb45d780cd7c66...
Once your learn to recognise the commonalities, you'll see examples everywhere. The most extreme and stereotypical version is the billboards written by some homeless people. You can probably picture it already in your mind's eye: A wall of very dense text with little whitespace or structure, and a mix of fonts and colours seemingly at random.
I had a brilliant mathematician friend who wrote like this. He would squeeze and entire semester's worth of study notes into a single sheet of paper, on one side. It was impenetrable gibberish to everyone else, but the colours and 2D positioning let him build a mental mind-map.
For people like this, if you reformat their code even a tiny bit, their mental map is invalidated, and they lose track of it completely and become upset. I discovered this (the hard way) when applying automatic code formatting tools to the codebases I mentioned previously.
Personally, I find this type of thing to be absolutely fascinating, because it's the intersection of many fields of study, and hence is under-studied. There's elements of pedagogy, psychology, literacy, compute science, etc...
It's an open question how we can get large groups of neurodiverse humans to collaborate on a codebase when they don't even "read" or "think" in compatible ways!
