Systems & Infrastructure Engineer

San Francisco, CA · Graduating December 2026 (BS Computer Science, USF)

I build high-performance systems tooling and isolated backend infrastructure, primarily in Rust. My work spans OS-level security mitigations (POSIX/kernel space), low-level memory management, and real-time AI agent architectures.

• uutils/coreutils — Contributor (Rust)

  Patched critical TOCTOU (Time-of-Check to Time-of-Use) symlink race conditions across install, ln, and tac during the private-disclosure window of a Canonical-funded Zellic audit. Authored cross-platform mitigations extending fd-anchored primitives (openat, mkdirat) to bypass dynamic path resolution vulnerabilities. Engineered an iterative parser for the expr utility, completely eliminating stack overflow faults for deeply nested inputs. (#13333)

  Fixes cited for CVE-2026-35356 and CVE-2026-35362, currently shipping in Ubuntu 26.04. (#9792, #10140, #10991, #11505)

• zed-industries/zed — Contributor (Rust)

  Resolved Git staging corruption in the user interface by patching the buffer_diff implementation. Addressed underlying synchronization issues between the text buffer and the diffing engine to prevent invalid hunk evaluations from propagating to the UI. (#60584, resolving #60424)

• pig — Private Inference Gateway (Rust)

  Building a capability-aware inference gateway that treats each running model, hardware target, and runtime configuration as a schedulable ModelInstance. Implemented constraint-based routing across heterogeneous backends using measurable capabilities and live runtime signals, including vision support, reasoning modes, placement policy, context limits, and availability. Exposes an OpenAI-compatible chat-completions API while keeping inference scheduling and execution cleanly separated from higher-level agent planning.

• simgit — Disk-Efficient Multi-Agent Git Worktrees (Rust)

  Engineered a copy-on-write Git worktree CLI (sg) designed for concurrent AI agent isolation. Bypasses standard checkouts by leveraging APFS clonefile, Linux reflink, and fuse-overlayfs fallbacks to share a single baseline's physical disk blocks across N agents. Benchmarked at 8.0x less physical disk usage for 8 concurrent agents compared to standard worktrees.

• Finlingo — Co-Founder & Lead Engineer

  Architected the backend infrastructure for an autonomous financial action-agent. Built a highly concurrent WebRTC voice pipeline (LiveKit) with custom SIP trunk telephony and VAD-based interruption handling. Secured user infrastructure using AES-256-GCM field-level encryption and isolated backend execution environments (LXC).

Pushing the limits of local agent infrastructure and sprinting toward Q3 goals at Finlingo. Actively exploring Systems, Core Infra, and Security Engineering roles for Q1 2027.
