AI systems engineer working on agent runtimes, inference infrastructure, and developer tooling. Go, Rust, TypeScript, Python.
My work usually sits in the layer between a probabilistic model and something someone has to sign off on: capability and authority boundaries, durable state, retained evidence, and the terminal surfaces agents run through.
- gripline — credential-containment gateway for inference APIs. Terminates reusable API keys at the trust boundary, reissues scoped internal assertions, and enforces lanes and hard limits, so a key that leaks authorizes less than it appears to. Go, Apache-2.0.
- Athena — local-first agent runtime built around a single authoritative reasoning loop: capability discovery, retained evidence, delegated execution, governed multi-runtime operation. Public beta. Python, MIT.
- Kontrol — local control plane for web and CLI coding agents: MCP workspace access, ACP worker dispatch, human review gates. Derived from Waishnav/devspace (MIT), extended with worker dispatch, durable review loops, supervised missions, and policy approvals. TypeScript, MIT.
- AegisKeys — Go TUI for key custody and provider configuration in coding-agent workflows, with a no-leak render check in the release gate. Ships signed releases with cross-platform binaries. MIT.
21 merged PRs into projects maintained by other people.
- QwenLM/qwen-code — 13 merged: auto-memory recall, per-model settings resolution, the shared tool-permission flow, settings.json comment preservation, cost estimation, search exit semantics.
- HarvardMadSys/hybridInference — 5 merged, 18 total: storage erasure races under advisory locks, trusted-proxy client-IP resolution, prefill-load-aware routing, prefix-cache locality validation.
- Unity-Lab-AI/ATree — authored the semantic and code-intelligence engine: scope-aware resolution with C3 MRO, multi-language symbol analysis, and the MCP integration behind it. That engine is most of what ATree became.
- josstei/maestro-orchestrate — added Qwen Code as a supported runtime, including the dynamic hook-adapter resolution that replaced its single-adapter design, plus a fix for LLM-emitted string numbers breaking phase lookups.
- SOLLOL — load balancing and routing for distributed Ollama clusters: node discovery, VRAM- and load-aware placement, health scoring, automatic failover. Published on PyPI.
- tsmigrate — deterministic TypeScript 6→7 migration engine: ordered transforms, atomic transactions, verification oracles, agent escalation over MCP.
- Agent-Interop — compatibility gateway between coding agents and local or hosted models, with a conformance and replay harness for tool calling.
- Portico — Go connection manager for local services and provider-backed tunnels.
- GitNexusRelay — real-time code-graph visibility for agents and humans, extending GitNexus.
Agent-governance work in progress — behavioral policy, durable state, and behavioral measurement as separable layers: CognitiveFrameWorks, CognitiveStateWorks, DigitalPsychology.

Precision machinist (±0.00015") → contract IT → self-taught systems work. B.A. Psychology, George Mason. Four years as the primary caregiver for my son, which is why the work is asynchronous and why I care about agents that hold up under constraints rather than agents that demo well.
