đź‘‹ Hi there
I'm Eduardo, a Senior Software Engineer specializing in financial infrastructure, blockchain systems, and scalable backend architectures.
Currently at LootRush, I'm working on a stablecoin platform that connects multiple blockchains with real-world payment systems, including on/off-ramps, card infrastructure, and cross-chain liquidity flows.
My work focuses on building high-performance systems for crypto payments and financial operations, handling complex scenarios like cross-chain transactions, asset conversions, and reliable transaction processing at scale.
