About
I'm Emile Harel. Self-taught developer — manual labour → backend → AI R&D in five years. CoSine is where I help people build software they understand. The thing I'm best at isn't writing code. It's teaching people to teach themselves, so the software they ship gets safer with every iteration.
Day job: Software Engineer in Capitec's AI R&D space. I build and run the memory and tooling that has to survive real users at real scale. CoSine is where I bring that same discipline to people now building their own software — business owners, small teams, solo founders.
South African, currently in Austria.

Curiosity. I read schemas before I read marketing. The interesting question is always the one underneath.
Ideas to life. A diagram is a hypothesis. The shipped system is the answer.
Off-screen. The success metric is what happens when the screen is dark.
