Esbri
Esbri is an escrow app for buyers and sellers who don't know each other. The money is held until the goods arrive, a small panel of arbiters decides if the two sides disagree, and every stage has a deadline so nobody can trap the funds by going quiet. The deal terms are public to anyone; the dispute conversation and its evidence stay private to the people involved.

Challenges and learnings
Never trust what a client says about who it is
check permissions against the source of truth rather than a cached copy
an error that guesses its own cause wastes more time than one that says nothing
convenience defaults quietly turn into safety holes
reproduce the bug before fixing it or you fix the wrong layer
free-tier limits shape the design more than preferences do
write the tradeoff down instead of hiding it.
