(Also known in realspace as Luciano Laje).
Software engineer from Buenos Aires, Argentina, working as an AI Engineer — building software with AI assistance, learning with it, and shipping on that footing. Working professionally since 2016, through consulting firms including Accenture and Globant.
🔭 Currently at Mercado Libre (MELI), researching and developing GenAI initiatives and tooling enablement for development acceleration.
- Python — most of what I write now, at work and outside it. Still shedding Java habits.
- C/C++ — tooling, scripting, CLI work, and the lower-level side of AI engineering.
- Swift/SwiftUI — learning it, aiming to ship my own software for Apple platforms.
I work with AI assistance across all of it. In these three I keep it on a short leash: I want to understand every line that ships. Outside them, when a project genuinely needs something else, I lean on it harder. Java is where I have the most mileage, and it still comes out when it's the right tool for the job.
Most of my public work is Claude Code and Codex tooling — design systems, an instructor, repo automation, local-model strategy — distributed through two marketplaces:
- lux-solari-plugins — the Claude Code catalog
- lux-solari-codex-plugins — the Codex catalog
A few of the individual pieces:
| three-axes-framework | Calibrates agent behavior across Mastery, Consequence and Intent, so it doesn't produce past my understanding |
| tri-swiss · lux-swiss | Two sibling house-mark design systems — related governance, distinct palettes |
| sage-instructor | Adaptive programming instructor with structured courses and verifiable exercises |
| hannah | Repo analysis plus hardware-aware local model recommendations |
| claude-trip-computer | Real-time cost and telemetry for Claude Code sessions |
| whiting | Wires a repo's CHANGELOG.md to GitHub Releases on a version tag |
I write about the craft — and about whatever else is in the way — at luxsolari.is-a.dev.
Analog and digital, taken seriously. I shoot 35mm, develop my own rolls, mix my own black-and-white chemistry, and make copy prints in a home darkroom. Colour gets developed and scanned. Digital is Fujifilm, edited toward classic film looks.

Ranked, narrative games, RPGs, sim racing. A good share of my analogies come from here.
