I debug agents where abstractions leak.

Contributor to production AI infrastructure across NVIDIA NeMo Agent Toolkit, Strands Agents, LiteLLM and the OpenTelemetry ecosystem.

Fixed structured-stream handling in Agent Security guardrails, preventing typed streaming chunks from being analyzed as Python representations. Introduced a shared typed stream-to-text conversion path with regression coverage across PII detection, content safety and output verification — NVIDIA/NeMo-Agent-Toolkit#2236.

Fixed forced structured-output retries where a generic tool_choice could allow provider-native tools to preempt the required output tool. Added regression coverage for the multi-cycle retry path — strands-agents/harness-sdk#4263.

Diagnosed incorrect model-capability metadata that forwarded unsupported reasoning_effort=minimal parameters to providers. The fix landed on main through the upstream registry batch PR, superseding my original proposal (#40547 → #40581).

Local-first, event-sourced, crash-recoverable, budget-bounded multi-agent delivery orchestrator.

308 offline tests · SIGKILL recovery · 64-way concurrent claim race · mypy strict + ruff clean.

A lightweight debugging and visualization tool for agent execution traces.

Agent Loop → Events → JSON IR → Visual Trace

Built for debugging agent execution, state transitions, tool calls and failures.

Fixing Bedrock operation-duration telemetry by moving shared client-level metric state into per-call contexts: correct per-call latency measurement, concurrent request state isolation, and an OpenTelemetry histogram regression test.

I care less about patch size and more about producing a complete evidence chain from failure to verified fix.
