Summary
👤
Senior🎓
Top SchoolLucas Ferreira is a Lead Software Engineer based in São Paulo with 12+ years building robust backend systems and leading multidisciplinary teams. He specializes in Node.js/TypeScript, microservices, and AWS serverless patterns, with repeated impact on performance and observability—designing CloudFront + Lambda@Edge caching that cut response times by 40% and instituting standardized error logging that captured 100% of critical errors. Lucas has driven database migrations and testing frameworks across PostgreSQL, MongoDB and QLDB, and champions fast local testing with tools like LocalStack to accelerate CI/CD. He pairs hands-on optimization (e.g., reducing API latency by 60% and audio playback to <500ms) with people leadership, mentoring engineers and owning hiring decisions. Now building the intelligence layer for U.S. construction data at Martelo, he combines deep platform experience with a knack for practical automation and measurable reliability gains. An avid pragmatist, he often surfaces non-obvious wins by focusing on testability and observability as first-class features.
