Rockstar🎓
Top SchoolKaviraj Kanagaraj is a Senior Software Engineer with 11 years of experience building high-performance, correct distributed systems and cloud-native infrastructure, currently at ClickHouse after senior roles at Weaviate and Grafana Labs. He specializes in backend engineering with deep hands-on expertise in Go, Kubernetes, Terraform and observability tooling, and has contributed to notable open-source projects like Grafana Tempo and Weaviate, improving deployment configs, gRPC APIs and serialization. Kaviraj bridges product and infrastructure concerns—designing scalable microservices, automating deployments, and hardening runtime configurations for production reliability. Colleagues rely on him for pragmatic refactors and test-driven fixes that reduce operational friction at scale. An engineer who enjoys low-level detail, he often surfaces subtle improvements (e.g., JSON struct tagging and runtimeconfig adoption) that yield measurable system robustness.
