Summary
Fernando Pradas is a Senior Software Engineer with 7 years of experience building secure, scalable distributed systems for high-traffic platforms, including Letgo and OLX Autos where he helped support tens of millions of users and thousands of RPS. He specializes in backend architecture and led the shift from microservices to Kafka-based Event-Driven Architecture, cutting response times and improving consistency while standardizing CI/CD and observability practices. As a hands-on engineering lead he balances mentorship, coding, and strategic decisions to align engineering with business outcomes and has driven measurable improvements in deployment speed, reliability, and code quality. He also explores SRE and DevOps, applies pragmatic engineering over perfection, and has taught backend frameworks at the master’s level with near-perfect evaluations. Early in his career he co-founded a crypto project and shipped audited Solidity contracts to mainnet, showing a knack for secure, production-grade solutions beyond traditional backends. Based in Oregon and originally from Spain, he thrives at the intersection of technology, leadership, and continuous improvement.
