Systems software engineer focused on Rust, Linux kernel networking, eBPF/XDP, and high-performance distributed systems. Founder of Spryzen, architecting low-latency packet-processing and security proxy infrastructure reaching 6.92M PPS and 4.83M sustained RPS. Author of 11+ upstream systems contributions merged and reviewed across Tokio, Wasmtime, smoltcp, Foundry, Cloudflare Pingora, and Hyper.
🛡️ Featured Systems Project: Spryzen
Hyper-Performance Network Security & Telemetry Engine — Zero-Allocation Packet Processing at Line Rate.
- ⚡ 6.92 Million PPS: L3/L4 wire-speed packet filtering via eBPF/XDP kernel bypass (Aegis XDP), dropping volumetric DDoS flood frames directly in the NIC DMA ring (
XDP_DROP). - 🚀 4.83 Million RPS: Sustained horizontal line-rate throughput across multi-core bare-metal proxy cluster node deployment (~200k–240k RPS per dedicated vCPU).
- 🔬 18.54 ns (0.0185 µs): Pure CPU zero-allocation inspection latency (53.9M ops/sec single-core capacity) verified across 1,000,000 requests.
- 🛡️ 100.00% OWASP CRS Mitigation Score: 39/39 attack vectors blocked with 0.00% False Positive Rate across clean traffic.
- 💉 Automated Penetration & Fuzzing Verified: Intercepts
sqlmap&nikto, fingerprints viawafw00f, and survived 10,000 extreme packet mutations with 0 crashes. - Lock-Free Concurrency & Zero-Allocation: Ring buffers, cache-pinned 256-byte branchless LUTs, and thread-local L1 hash caches with 0 bytes of heap allocation on the hot path.

PR #27049 | Snapshot manifest validation & zero-chunk division guard: Enforced SnapshotManifest::validate() to reject malformed manifests with blocks_per_file == 0 prior to expansion. Hardened ChunkedArchive::num_chunks() and chunk_relative_path() with saturating arithmetic to prevent zero-division panics during snapshot downloads. |

PR #4191 | Watch stream heartbeat recovery: Fixed silent stream freeze in PendingTransactionBuilder::watch (#4181, #3881) when HTTP pollers skip the exact mined block due to network jitter. Automatically scans skipped block ranges across poll heartbeats to ensure pending transactions are never hung indefinitely. |
