About Archy Wilhes

Co-founder & CTO of Castella. 22 years of age. Singapore-based. Preparing to do a master’s in comp sci and then one in art.

  1. I had formally reduced the Erdös-Szekeres conjecture into a constraint unsatisfiability problem [pdf on arxiv] && come up with a new proof for the Moessner’s theorem with double induction [pdf on arxiv] && completed a Ph.D. module in Programming Language Theory - all these when I was 19. And then I lost my virginity.

  2. I founded my first start-up at 16 (back in 2012) and eight months later it died. I began freelancing & working for different start-ups since then.

  3. I was the lead developer & 5% shareholder of a start-up that got on to TechCrunch Disrupt London 2016. Still, just like most start-ups eventually it died.

  4. I speak English, Cantonese, and Mandarin fluently. But most importantly, I run Arch Linux and use spacemacs -)
