Systems Architecture & Application Security

I build high-performance, memory-safe infrastructure and security tooling. My core focus is on systems-level Rust, POSIX vulnerabilities, and dynamic execution environments.

🏗️ Featured Engineering & Research

  • uutils/coreutils (Open Source Contributor) Contributor to the cross-platform Rust rewrite of the GNU coreutils. Recently mitigated OS-level TOCTOU (Time-of-Check to Time-of-Use) race conditions utilizing openat for secure directory traversal.

  • LAO (Local AI Orchestrator) A commercial-grade, multi-modal AI execution engine written in Rust. Features a custom Directed Acyclic Graph (DAG) scheduler and a dynamic plugin architecture that loads compiled .dylib/.so C/C++ inference engines at runtime via FFI.

  • Argus A high-performance, multi-threaded File Integrity Monitor (FIM). Implements parallel SHA-256 cryptographic hashing to detect unauthorized filesystem mutations across massive directories.

  • Finlingo CTO / Lead Architect. Managing the backend infrastructure and shipping cross-platform iOS/Android builds.

⚙️ Technical Stack

  • Languages: Rust, C/C++, Python, POSIX Shell
  • Systems: FFI / ABI Stability, Dynamic Library Loading, Concurrency (Tokio), Memory Safety
  • AppSec: Vulnerability Mitigation, Fuzzing, Race Condition Analysis, Cryptography
