Principal backend engineer and Node.js cloud-native architect.
ColombiaWhat I'm looking for
I’m a Principal Backend Engineer with 13+ years architecting cloud-native, serverless systems on AWS. I lead mission-critical migrations from monolithic, on-premise setups to fully serverless architectures that keep services continuously available.
At Galicia Bank, I’m driving the modernization of core banking infrastructure—payment settlement and accounting—using Lambda, Step Functions, EventBridge, and DynamoDB. I delivered zero-downtime deployment across payment flows, designed event-driven workflows processing 150K+ transactions daily with sub-second latency, improved DynamoDB query response times by 65%, and reduced MTTR by ~50% with proactive Datadog monitoring and alerting.
I also bring deep expertise across backend engineering and security, including Node.js/TypeScript and Golang, distributed systems, and event-driven architecture. From identity management work with OAuth2/OpenID Connect, SAML, LDAP, RADIUS, PKI, and WebAuthn to high-performance integration platforms and serverless microservices, I mentor teams and reinforce clean, auditable engineering practices—supported by AWS certification and Scrum/Agile experience.
