I'm a software engineer at Sage. I build systems, and I care more than I probably should about how they're put together.
Most of my time outside of that goes into tools, scripts, and configuring things until they work exactly the way I want — five hours well spent on a 0.0001% improvement, every time.
I believe in libre and open source software — use it, contribute when I see the need, and genuinely care about the distinction.
Sometimes I write things down at devadathanmb.in — from how systems work to how everything else does, sometimes.
