Building hyper-performance edge security engines, sub-microsecond network inspection runtimes, and resilient systems software in Rust, C++, and Linux.
🛡️ Featured Systems Project: Spryzen+
Hyper-Performance Network Security & Telemetry Engine — Zero-Allocation Packet Processing at Line Rate.
- 4.83 Million RPS packet ingestion throughput on single-node bare metal.
-
207 ns P99 latency with zero dynamic heap allocations on the packet wire path (
Cow::Borrowedstack slices). -
27.99 ns Zero-Alloc Fast-Path Normalization: Bypasses heavy regex and unicode normalization passes via a compile-time 256-byte lookup table (
NEEDS_DEEP_NORM_TABLE). -
0.00 ns
$O(1)$ RISKY_CHAR_TABLE: Replaced 24 chained character branches with single-instruction vectorized byte lookups. - Lock-Free Concurrency: Ring buffers and atomic ring queue scheduling eliminating thread context-switching locks.
-
Adaptive Rayon Bulkhead: Inline sub-microsecond processing for standard payloads (
$\le 8\text{KB}$ ); bulkhead thread-pool isolation for jumbo payloads ($> 8\text{KB}$ ) protecting Tokio worker threads from ReDoS.

|---|---|---|---|
Cloudflare Pingoracloudflare/pingora(22,000+ ★) |
PR #996 | RFC 9110 §15.6.6 upstream timeout mapping: Resolved upstream timeout classification in Cloudflare's core reverse proxy. Mapped upstream connect, TLS handshake, and read/write timeouts to 504 Gateway Timeout instead of generic 502 Bad Gateway. |

Tokio Async Runtimetokio-rs/tokio(27,000+ ★) |
PR #8405 | Semaphore integer overflow fix: Resolved critical permit-leak bug in SemaphorePermit::merge where permit counts exceeding u32::MAX wrapped and permanently leaked permits upon drop. Converted storage to usize with safe checked arithmetic. |

Astral uvastral-sh/uv(45,000+ ★) |
PR #21457 | Cross-process file lock timeout propagation: Decoupled lock acquisition from static timeouts by threading configurable timeout options through EnvironmentOptions across Astral's entire workspace toolchain. Passed all 55 CI matrix suites across 11 OS/arch targets. |
