Senior🎓
Top SchoolLauan Guermandi is a Lead Software Engineer and architect based in São Paulo with 9 years designing cloud-native, event-driven systems for fintech and enterprise clients. He specializes in Azure and GCP, .NET backend stacks (C#, ASP.NET Core), Kubernetes, Kafka/RabbitMQ, and resilient patterns like CQRS, Event Sourcing and SAGA to deliver scalable distributed systems. At Stone and previous banking and finance projects he has moved from senior engineering to technical leadership, blending hands-on development with system-level architecture and team mentoring. Certified in Azure fundamentals and data, he emphasizes Clean Architecture, DDD and pragmatic SOLID practices to keep systems maintainable under scale. He publishes technical insights on Medium and maintains an active GitHub, signaling a commitment to sharing learnings beyond day-to-day delivery. A less obvious strength is his track record of bridging operations and design—bringing observability and monitoring practices (Datadog, ELK, Grafana) into architecture decisions early.
