Senior🎓
Top SchoolGuilherme Dos Santos is a Golang specialist and founder with 16+ years building cloud-native backends, event-driven systems, and DevOps automation across fintech, e-commerce, and AI. He’s driven architectural transformations at scale—defining Go standards at Qonto, cutting search latency sixfold at Delivery Hero, and shipping LLM-powered feedback platforms at Birdie. Comfortable across the stack, he pairs Kubernetes, Terraform, Kafka/Pub‑Sub and CI/CD expertise with hands-on experience in frontend SPA work and embedded systems from earlier roles. As an entrepreneur he built and evolved a SaaS ERP into a microservices platform, and he continues to maintain indie products like a multi-currency net‑worth tracker. An active open-source contributor, he’s contributed to projects such as gRPC‑Gateway and the Elastic Go client, bringing pragmatic API and tooling improvements. Based in Berlin and open to consulting, he favors greenfield projects where clean code, scalable architecture and product thinking meet measurable impact.
