Why I rewrote our deploy pipeline in Go
From 7-minute Bash spaghetti to a 90-second Go binary. The case for treating CI scripts as real software.
Lx8 Labs — a small studio in the Bell Labs lineage. We build
engineering tools, ship open-source research, and
run fixed-scope consulting for teams that take operability seriously.
Small, fast, honest software.

Lx8 Labs was built around the intersections of DevOps, AI, and theoretical physics — three lineages that don't usually share a roof. The studio is a single small institution carrying that work forward, piece by piece, project by project.
My work spans cloud infrastructure, developer tooling (Tupã IDE), and original research on light-gravity interactions. I believe the best engineers understand the fundamentals deeply — which is why every course and product I build starts from first principles.
Lx8 Labs is inspired by Bell Labs: a place where scientific curiosity and engineering excellence coexist. We're just getting started.
Practical, in-depth courses built by a DevOps engineer. No fluff — just what works in production.
39 classic algorithms as interactive 3D visualizations — from Euclid's GCD (300 BCE) to Tim Sort (2002). Watch the source code highlight in lock-step with the 3D scene as live variables update.
i, j, arr[mid], distances, memo tables — anything that matters.Hardware kits born from our studio, comprehensive books, and partner collaborations.
Each project is a bet on a future that doesn't exist yet.
Three-channel taxonomy of light–gravity coupling. An original research framework by Alexei Ferreira (2026) with interactive 3D visualization.
Infrastructure for ideas that scale globally.
Strategic engineering guidance from someone who's shipped it in production. No jargon — just results.
Real-time 3D built with Unity 6 — physics, game mechanics, and interactive simulations running natively in the browser via WebGL.
The three-channel taxonomy of light–gravity coupling — interactive 3D exploration of mass density, angular momentum, and the cosmological constant.
Video breakdowns of complex engineering patterns, physics visualizations, and studio logs.
Once or twice a month: a deep technical write-up on whatever we just shipped or learned. DevOps post-mortems, AI experiments, paper breakdowns. No marketing drips.
From 7-minute Bash spaghetti to a 90-second Go binary. The case for treating CI scripts as real software.
Three.js + 350 lines of CSS. No framework. Why constraints made this site faster than every framework alternative.
What changes when you stop selling time and start selling outcomes — and why most engineers should try it.
