Summary
🤩
Rockstar🎓
Top SchoolAlexandre Liberato is a senior back-end engineer based in São Paulo with a decade of experience building cloud-native financial and fintech systems using Go, Java and clean architecture. He has led design and implementation of production-grade microservices—most notably the open-source Amazing Ledger—applying DDD, TDD and instrumentation practices to deliver auditable, observable payment and banking services on AWS/Kubernetes. A pragmatic problem solver, he drove the first OpenTelemetry adoption at his company and routinely turns prototypes (PDF extraction, CEL rule engines) into low-latency, memory-efficient services. His background as a founder of an access-control startup gives him hands-on expertise in embedded systems, OCR and performance tuning, and he pairs that breadth with disciplined engineering processes like small PRs, semantic commits and versioned architecture docs.
