High-Throughput Distributed Event Streaming & Telemetry Mesh
Distributed Systems & Infrastructure Lead · Oct – Dec 2025
Engineered an event-driven telemetry and distributed tracing collector capable of processing 100,000+ metric spans/sec with Kafka, ClickHouse, and OpenTelemetry.
What I learned
- ✓Designed partitioned Kafka topics with compacted changelogs and idempotent producer semantics for exactly-once processing guarantees.
- ✓Implemented vectorized ClickHouse analytical aggregations, optimizing columnar compression codecs to achieve an 8x reduction in storage.
- ✓Developed automated SLO tracking dashboards with Grafana and Prometheus alerts for tail-latency (p99) anomaly detection.
