Hi! This is Justin 👋

Flightdeck - Your AI software engineering team 🧠

Flightdeck is an orchestration layer for AI coding agents. Works with GitHub Copilot, Claude API, Gemini CLI, Codex, and more. Works out of the box with your existing clis: npm install -g @flightdeck-ai/flightdeck.

Additional projects I contribute to (pinned)

• ONNX
• PyTorch
• ONNX IR
• ONNX Script
• ONNX Adapter for Model Explorer
• ONNX Safetensors
• onnxruntime-mlx: Fast MLX execution provider for ONNX Runtime on MacOS.
• onnx-genai: Prototype of the next runtime for ONNX, in Rust.
• mobius: Convert any model to ONNX (with the help of AI).

Some of my other projects

• Web Praat: Praat as a web app.
• GitHub Attention Set: Code review Attention Sets for GitHub.
• lintrunner-adapters: Adapters and tools for lintrunner. Also available as a GitHub action: lintrunner-action
• onnx-shape-inference: Symbolic shape inference for ONNX using sympy.
• onnx-doctor: Linter for ONNX models
• onnxruntime-easy: Simplified APIs for onnxruntime to allow you to call an ONNX model like a Python function.
• torch-code-tracing: Code trace your PyTorch model and understand its execution.
• clang-format-black: A clang-format config that mimics Python's black formatter style.
• (gist) Best practice for importing in Python
• (gist) Python container typing hierarchy
• diagrams: My diagrams for technical documents.
• torch-onnx-op-matrix: torch.onnx operator support status
• onnx-test-models: Structure only models for testing ONNX tools.
