We build and run infrastructure and software.

A studio from Cartago, Costa Rica. From the Linux box and the hypervisor up to the API, the data pipeline, the web app, and the AI agent. Security and penetration tests are how we earn the right to operate a stack. On confidential systems, agents see metadata only; humans approve the script; the data never enters the model.

ls projects cat security.md contact

~/infra

$ uname -a

Arch, Debian/Ubuntu, FreeBSD, RHEL, and Amazon Linux on Proxmox VE, KVM, and bare metal. We provision, harden, and operate the machines our software runs on.

~/oss

$ git remote -v

We build on open source and contribute back, and release our own tooling under the CodeStrux organization on GitHub.

cat security.md

Security and penetration tests.

This is a CodeStrux strength. We pentest the environments we operate and the ones you hire us to test — hosts, networks, identity, secrets, and the path from laptop to prod. Findings stay with the operators. We close exposure with the team that owns the box.

On confidential systems, the same discipline: agents see metadata only. The CodeStrux Tech team approves the script. The payload never enters the model.
