A browser UI for pricing derivatives with QuantLib
Clean UI for derivatives pricing, but QuantLib bindings and domain-specific modeling already exist.

Pure ESM library for heat and salt diffusion models makes this reusable beyond just steak.
Home cooks who want precision grilling backed by physics

Along the way I calculated exactly how far in advance to salt meat (spoiler: even when it's frozen!), realized the best dry brine is usually "cling brine" (covered), derived approximate charcoal quantities with physics, and much more.
As with the pancake calculator[1], I did an insane amount of grilling to develop this. And like the pancake one, it's a pure ESM library with frameworks around heat and salt diffusion and the other underpinnings, making it easier to develop more recipes.
