Akshant Sharma

Staff Engineer. I build high-throughput distributed systems and the infrastructure layer that sits underneath product features — ingestion engines, storage primitives, real-time event pipelines.

Currently building infra-ai-streaming — an AI inference observability platform in Rust.

What I'm Building

infra-ai-streaming in progress

An open-source AI inference observability pipeline built for the event volume and metric cardinality that standard monitoring tools break under.

Rust ingestion engine → Kafka → Go consumer → ClickHouse → Grafana
  • Axum HTTP server with channel-based backpressure and per-tenant rate limiting
  • Circuit breaker with Redis overflow buffer and Dead Letter Queue
  • Z-score anomaly detection on inference latency per model
  • Helm charts with HPA scaling on Kafka consumer lag
  • Target: 1M events/min, sub-100ms ingestion P99

Technical Bets

Things I'm doubling down on:

  • Rust for systems programming where performance guarantees are non-negotiable
  • AI infrastructure — inference pipelines, LLM observability, cost optimization at the API layer
  • Kafka internals at scale — partition strategy, consumer group design, backpressure mechanisms
  • ClickHouse for analytical workloads over high-cardinality event streams
  • Kubernetes — operators, eBPF-based observability, cost-aware autoscaling
