JXTNGX

I build Cursor-first labs and factories: learn a skill/stack by typing it in a lab, or specify a product or task intent and let a Cursor team ship it in a factory.

Trajectory: MS in AI → open source contributor and developer advocate for PyTorch Lightning, LitGPT, and torchmetrics → AI/ML Engineer for applied AI and autonomy.

Stack: PyTorch, Hugging Face, NVIDIA, Cursor, Grok, LangChain + LangSmith, AWS.

Compute: NVIDIA DGX Spark and M5 Max 48GB


Cursor-first

The IDE is the operating system. Grok and Cursor subagents are mentors or a staffed team — never a mystery box that owns the repo.

Surface Job
Lab You write every line of domain code. Agents explain, quiz, review. Official docs are the spine. Definition of done: you can recreate it from a blank file.
Factory You write the spec (@init-*, discovery). Chief Architect, SME, Scrum, engineers implement the spec. Not a lab.
Command Factory Directorate (ops + engineering). Routes a campaign across labs and factories. Does not implement.
Plugin Cursor plugin (rules, skills, agents, commands). Ships into the editor, not as a product repo the user types by hand.

Commands start work (@start-lesson, @init-extension). Commands do not silently finish it in a lab.


Design

Grok and Cursor exponentiate output. They do not replace T(n) / S(n), profiles, linters, call graphs, or the engineering floor.

Language contracts: Python, TypeScript, Swift, Kotlin (Jetpack Compose), Rust, C++20 (CUDA). First principles include AI-amplified craft plus common software engineering practice and design patterns as named tools for real seams.

Labs

Beginner → advanced in one language and topic. Harnesses do not do the exercise.

Repo Topic
cursor-rust-lab Rust
cursor-cuda-lab CUDA C++20
cursor-robotics-lab C++20 + ROS 2
cursor-rtos-lab Zephyr RTOS (native_sim / QEMU)
cursor-langchain-lab LangChain agents (Python / TypeScript)
cursor-data-engineering-lab Python DE for AI/ML
cursor-game-theory-lab Algorithmic game theory (NumPy / PyTorch)

Factories

Spec-driven boilerplate. Init interviews, then a Cursor team ships tickets.

Repo Product
cursor-fullstack-factory Fullstack app
cursor-deep-learning-factory PyTorch / Hugging Face
cursor-langchain-factory LangChain, provider-agnostic (LangSmith, Harbor)
cursor-grok-factory Grok + Cursor SDK (LangSmith, Harbor)
cursor-extension-factory Cursor/Open VSX extension (TS host + Rust crate)

Command

Fleet C2. Ops liaises; engineering routes. Example campaign: tabletop swarm (Reachy Mini-class + MicroDuck-class).

Repo What it is
cursor-factory-command Directorate over the factory fleet

Developer Tools

Products you run, not curricula.

Repo What it is
