About Keerthi Kumar S R

I build distributed systems that don\'t fail — and define the architecture that makes sure they never have to.Over 8 years, I\'ve moved from writing the code to setting the technical direction — designing systems at 30K+ PPS and 10K+ QPS, leading zero-downtime migrations across mission-critical infrastructure, and driving platform decisions that compound across engineering orgs. I operate where ambiguity is highest and the blast radius of a wrong call is largest.At Intuit, I spearheaded the zero-downtime migration of Golden Signal observability pipelines handling 30K+ PPS and 15K+ TPS — not just executing the migration, but designing the parallel-environment strategy and phased rollout blueprint adopted across 6 high-scale pipelines. I architected a multi-region Grafana and Mimir query layer with automated AWS RDS Global Writer failover, validated at 10K+ QPS. I drove org-wide security governance automation for users — defining the permission model, building migration tooling, and delivering 100% audit overhead reduction with zero end-user disruption.At Rakuten, I defined and executed the technical strategy that scaled the SixthSense Observability platform 50x in 3 months — redesigning the backend architecture with streaming services, back-pressure handling, and query optimisation. I reduced GC pause times 3x, delivered 30% annual cost reduction via hot/cold storage architecture, and built the metrics correlation framework that enabled automated root cause analysis — all within 3-month delivery windows.What I bring at Staff level:→ Technical strategy & org-wide architecture decisions under ambiguity→ Engineering multiplier: I set blueprints, write design docs, and unblock teams — not just ship code→ Zero-downtime systems design for workloads where failure is not an option→ Platform cost architecture — FinOps thinking baked into every design decision→ Cross-functional leadership across infra, product, security, and customer successDeep expertise: Java · GoLang · Kubernetes · Kafka · Grafana · Prometheus · Mimir · Numaflow · Elasticsearch · ClickHouse · gRPC · GCP · AWS · Redis · RBAC · Federated IdentityCurrently Senior SWE at Intuit. Actively targeting Staff and Principal Engineering roles at companies operating at extreme scale — observability, platform engineering, distributed data infrastructure.Let\'s connect if you\'re solving hard infrastructure problems.
