TopDev rebuilt our payments core while the old one was still running — zero downtime, zero lost transactions. They operate like an elite internal team, not a vendor.
Every agency promised us 'AI features.' TopDev was the only one that showed up with evaluation metrics and shipped a copilot that actually resolves tickets.
Two audits, fifty million fuzz runs, and not a single exploit since mainnet. In DeFi, that's the only metric that matters.
They cut our AWS bill by a third and doubled our deploy frequency in one quarter. The infrastructure now feels like a product, not a liability.
