Bobby Mathews
Rust systems engineer. I build distributed infrastructure and write about it.
About
I work on high-performance Rust infrastructure: async runtimes, data pipelines, and systems where latency and throughput numbers matter. Current focus is Solana infrastructure: RPC connection pooling, Geyser gRPC streaming, and time-series indexing pipelines. I also build formal verification tooling for structured document workflows.
Writing
I write about difficult problems in distributed infrastructure and the solutions to close the gaps. Recent work includes a deep dive on Tokio executor starvation failure modes.

Featured Project
Production-grade Solana data pipeline: RPC pool → Geyser gRPC → TimescaleDB → query API. Targeting sub-200ms slot-to-indexed latency for trading and analytics workloads.
RPC connection pool with health-aware load balancing and circuit breaking. Geyser gRPC consumer for real-time streaming. TimescaleDB sink with hypertable optimization. Public query API and live dashboard.

Other Projects
Constrained document verification engine for patent prosecution. Formal grammar verification runs in WASM client-side; local LLM inference via WebGPU. Targets the semantic layer that existing patent tools do not cover.

Controlled benchmark isolating Tokio executor starvation under blocking workloads. Key finding: 101x p99 latency increase under starvation. EC2-controlled environment, reproducible results.

Spot instance orchestration prototype for GPU inference. EC2 tag-based worker discovery, interruption-aware draining, stateless failover. Worked end-to-end; not pursued for economic reasons.
