I live in Bangkok and spend most of my time outside on foot — football, badminton, wandering around with no particular destination, and talking to strangers for longer than is strictly normal. When I'm indoors it's usually at the piano, jamming with whoever will join me. A lot of the writing here started as one of those wanderings.
The work is real but it isn't the whole of me. I got curious about computers around grade 7 and never really stopped; that took me through backend work, data pipelines and a stint of AI research, mostly by saying yes to things I wasn't qualified for yet. I'm not especially good at any of it. I just like the bit where something confusing slowly stops being confusing.
Bangkok. Football, badminton, wandering, piano when the neighbours allow it, too many half-written drafts.
