Just call me Keilo.

I’ve built products for people the mainstream ignores: those handed tools that were never designed with them in mind. I’ve led innovation at global financial institutions, worked at the edge of human-centred design and emerging technology, and shipped platforms that operate across languages and contexts most product teams never encounter. I’m an AI practitioner. I think in systems. I apply the same standards to a passion project as to a nine-figure platform.

I’m also a reef keeper.

Three tanks. A 900-litre mixed reef. A 500-litre mixed reef. An 800-litre fish-only that is, honestly, the most forgiving of the three. Together they represent years of iteration, some genuine losses, and a continuing education in patience, water chemistry, and the particular humility that only a closed ecosystem can teach you.

ReefDiary came from a single frustration. When something went wrong, I had no reliable record of when things started to shift. Parameters measured but never connected. Notes scattered across four apps. Memory I couldn’t trust. I build platforms for a living. I work with AI daily. And I still couldn’t answer the one question every reefer eventually needs to answer — what changed, and when?

So I built what I always wanted. A logbook that thinks. A system that sees the trend before you do. A tool built with the same seriousness the hobby demands.
