Hi, I'm Ankur Rathore

Lead Systems Architect | High-Throughput Data Pipelines | Linux Performance

I am a Technical Lead with 12+ years of experience designing and scaling distributed backend systems. My day-to-day involves architecting enterprise IoT platforms and event-driven data pipelines (Python, Go, Kafka, AWS).

In my open-source work, I go as close to the metal as possible. I build zero-cost abstractions, eBPF network filters, and Linux kernel observability tools natively in Rust to eliminate CPU overhead and solve extreme tail-latency bottlenecks.

Core Stack & Technologies

  • Systems & Performance: Rust, C, eBPF (Aya/XDP), Linux Kernel ABI, Custom Memory Allocators
  • Backend & Distributed: Python (FastAPI/Django), Go, Kafka, Apache NiFi
  • Cloud & Infrastructure: AWS (Serverless & VPC), Kubernetes, Docker, Rancher
  • Databases: PostgreSQL, CrateDB (Time-series), DynamoDB, Redis

Current Research & Open Source

  • Building xdp-ai-guard: A line-rate eBPF/XDP firewall in Rust protecting AI inference servers from volumetric DDoS attacks.
  • Building tsastat: A Linux Thread State Analysis (TSA) profiler extracting microsecond-level CPU scheduler metrics.
  • Optimizing sharded-timing-wheel: Implementing $O(1)$ constant-time scheduling and custom Slab Allocators in Rust to eliminate heap fragmentation.
