I'm Jérémie — I teach computer science and build tools for thinking with AI.

• ADRs4AI — git-native tooling for deliberative programming: your decisions become first-class, compounding artifacts of human-AI collaboration. Start with the collaboration template.
• Computationally Assisted Metacognition — a graduate course at Penn on thinking with — not through — AI.
• lumbroso.computer — the hub for everything else.

• 🕰️ passage-of-time-mcp — an MCP server giving language models temporal awareness (719★)
• 🗑️ free-disk-space — a GitHub Action running in thousands of CI pipelines daily (708★)
• 📊 comma — CSV for humans, in Python

(This profile is molting from its previous state — a longer brief on what changed is coming.)

1. Software engineering is nascent. You thought software was eating the world before? You haven't seen a thing yet. 🥰🤩
2. AI is empowerment tech — for individuals and communities first, whatever the loud voices fighting for control of the narrative would have you believe. Let's build our way out of the collective-action problems we've been stuck with.

I believe in us. 🧡

These are my favorite services because their scaling formulas are smooth, their costs low, and their engineering excellent — and all have an MCP server (no interface clicking, all LLM delegating):

• Alacritty: https://github.com/alacritty/alacritty — cross-platform OpenGL terminal with no tabs and nothing else!
• Just: https://github.com/casey/just — the Rust universal Makefile-alike; absolutely the Swiss-army knife you need in the era of LLM-assisted building! I use it in all my projects — the only ones that don't have just are the ones I haven't worked on since discovering it!!

• Front-end: GitHub Pages
• Back-end: Render (main reason: Blueprints)
• Database: Neon
• Serverless Data: Upstash
• Serverless Back-end: Vercel

• Domains: Spaceship
• Email: PostmarkApp

I work in VSCode most of the day; I am grateful for such a kick-ass editor. I still remember the late 90s when I scored a student license for Visual Studio 6. I had a tumultuous few years, with an extended collaboration with OmniCore X-develop, emacs, then PyCharm, but none of those ever felt right the way VSCode feels right.

• ADRs for AI Manager, to keep track of my Architectural Deliberation Records, and all my collaborators' inquisitive questions
• Peacock by @johnpapa, to distinguish among your dozens of project windows
• Terminals by @fabiospampinato, to summon your army of terminals/agents

This is a screenshot of my VSCode window for the moreover project, a less/more-like pager for LLMs, with Ribbon 5 (Claude Fable 5) and Lector 6 (GPT 6 Astra). The terminal also quietly shows something I care about: inter-vendor coordination — Lector (via Codex) waking and messaging Ribbon through pneumatic, our wake-and-inbox layer, so models from two vendors collaborate on one deliberation record.
