Nix Consultancy

Victor provides Nix consulting for organizations that need reproducible, secure development environments and cloud infrastructure. Based in Mexico City, he works with teams across Latin America and globally.

What I help with

Dev Environment Provisioning

Reproducible developer setups with NixOS and Home-Manager. Every engineer on your team gets the same tools, same versions, same behavior — no more “works on my machine.”

Security Hardening

Nix provides cryptographic guarantees on every dependency. Auditable build graphs, hermetic builds, and reproducible deployments eliminate entire classes of supply-chain vulnerabilities.

Cloud & CI Provisioning

NixOS-based server infrastructure, container-less deployments, and CI pipelines built on Nix. Deterministic builds from development to production.

Migration & Training

Incremental adoption strategies — from adding a single shell.nix to full NixOS infrastructure. Training for your engineering team on Nix fundamentals and Dendritic patterns.

Clients in Mexico

Three organizations in Mexico are currently using Nix with Victor’s guidance:

Financial services firm

Adopted NixOS for security-hardened development environments. Every developer workstation is provisioned from a reproducible NixOS configuration, ensuring compliance with internal security policies and auditability of all installed software.

Software consultancy

Uses Nix for cross-project development environment provisioning. Teams switch between client projects with different toolchains (Java, Python, Node.js) instantly via Nix flakes — no global installs, no version conflicts.

Cloud infrastructure startup

Deployed NixOS-based cloud provisioning for their platform. Server configurations are version-controlled, testable, and rollback-safe. CI pipelines use Nix for deterministic builds across staging and production.

Why Nix?

• Reproducibility — builds are deterministic, byte-for-byte identical across machines
• Security — every dependency is pinned by hash, eliminating supply-chain attacks
• Rollbacks — atomic system updates with instant rollback on failure
• Multi-project — developers work on multiple projects without dependency conflicts
• Auditability — the entire dependency graph is inspectable and verifiable

Engagement

Consulting engagements are flexible — from a few hours of guidance to ongoing infrastructure support. Victor brings the same quality and depth to client work as to his open-source ecosystem.
