Last week, we attended the Social Safety Net Product Studio Convening and came away inspired! Thanks to @SchmidtFutures for making it happen. At PolicyEngine, we're harnessing tech to help households, policymakers, and developers compute the impact of safety net benefits.

With Dynare folks moving to Julia (github.com/DynareJulia/Dynar…), you can expect to see more of this. In fact, they are looking to hire #julialang developers, so if you're interested see (discourse.julialang.org/t/th…). This work wasn't with that group, but we collaborate!
