Nix Infrastructure & Embedded Systems Consulting

Flaky builds, unreproducible environments, and slow CI pipelines cost your team time every day. I fix that by making your entire stack declarative, versionable, and auditable with Nix.

I specialize in reproducible build infrastructure, embedded Linux, and systems programming in Rust. I maintain packages in nixpkgs, contribute to the Linux kernel, and have introduced Nix across firmware and software teams in production environments.

What I Offer

Declarative Infrastructure with Nix

Most build systems accumulate hidden state over time. Nix eliminates that by making every dependency explicit and every build reproducible from source. I have used this in production across firmware, kiosk systems, and CI/CD pipelines.

I can help you:

  • Design and implement Nix-based CI/CD pipelines for reproducible builds across environments
  • Migrate legacy build systems to declarative Nix configurations
  • Write custom NixOS modules for your specific infrastructure needs
  • Build containerized and VM-based testing environments that spin up in seconds
  • Create development environments that work identically for every team member

Automated Testing & Quality Assurance

Testing embedded and Linux-based systems is hard because the environment matters as much as the code. I build test infrastructure that runs your software in environments that mirror production exactly, using NixOS VM orchestration and hardware-in-the-loop setups.

Services include:

  • Integration testing across multiple services with automated orchestration
  • Kiosk and embedded system test automation
  • Continuous testing pipelines integrated with your existing CI tools
  • Test environments provisioned from the same Nix configuration as production
  • QEMU-based virtual hardware testbeds for testing firmware and embedded software without physical devices

Secure Embedded Systems

Security in embedded systems has to be built into the hardware, not bolted on afterward. I implement trusted execution environments and hardware-backed security primitives for devices where compromise is not an option.

Expertise in:

  • OP-TEE trusted application development and integration
  • Hardware-backed cryptographic operations and secure key storage
  • ARM TrustZone implementation for secure/non-secure world isolation
  • Secure boot implementation for embedded Linux targets

Systems Programming & Performance

When correctness and performance are non-negotiable, I write systems code in Rust. I also work at the kernel level when the problem lives there, including driver development and platform support.

I specialize in:

  • Rust development for systems where reliability and memory safety are critical
  • Linux kernel driver development and platform support (current maintainer of Dell PC platform support)
  • Memory-safe refactoring of critical C codebases
  • Cross-compilation for embedded targets including aarch64

Who I Work With

I work best with teams that have hard infrastructure problems and the technical appetite to solve them properly.

  • Platform and DevOps teams struggling with unreproducible builds, slow CI, or brittle deployment pipelines
  • Embedded and firmware teams building secure IoT devices, kiosks, or edge computing platforms
  • Security-focused teams requiring trusted execution environments and hardware-level security primitives
  • Product teams dealing with flaky tests, complex multi-service architectures, or environment drift between development and production

Engagement Models

Consulting Projects – Fixed-scope work with defined deliverables, typically 2 to 8 weeks. Ideal for migrations, proof-of-concepts, or building specific infrastructure from scratch.

Retainer Arrangements – Ongoing access to specialized expertise for teams that need regular support, code review, or architectural guidance.

Architecture Review – A focused engagement to evaluate your current systems and deliver concrete recommendations with an implementation roadmap.

Why Work With Me

Nix, Rust, OP-TEE, and Linux kernel development is a rare combination. Most engineers know one or two of these deeply. I use all of them together in production, which means I can see problems that specialists in any single area would miss.

I also focus on leaving teams better than I found them. Every engagement includes knowledge transfer, documentation, and clear explanations of architectural decisions. You should understand what I built and why, not just that it works.
