Octanix Americas LLC
Elixir/BEAM systems, Bayesian inference, data science and analytics. Two decades of enterprise systems engineering
Octanix Americas LLC is an independent Elixir/OTP engineering practice in Detroit, MI, focused on the harder end of BEAM systems work. Active since 2025 under Octanix Americas; the underlying practice extends back to 2011 (Credorax PCI-DSS payment processing, Boston + Malta). ## Engagement profile: architecture-level Elixir/OTP design and implementation, performance engineering and observability, Rust NIF hot-path integration for performance-critical inner loops, regulated-environment system delivery (PCI-DSS, financial services, healthcare-class), and BEAM-on-FreeBSD specialty work. Fully remote, async-friendly, all US and Canada time zones. ## Capability anchors — public artifacts: - eXMC (github.com/borodark/exmc) — Bayesian probabilistic-programming framework on Elixir/BEAM. NUTS sampler, dual-averaging step-size adaptation, mass-matrix estimation, EXLA/EMLX/BinaryBackend runtime swap, Rust NIF tree-builder hot path. Seven-phase optimization study landed at 1.9x faster than PyMC on hierarchical models. - sim_ex (github.com/borodark/sim_ex) — discrete-event simulation on Elixir with 23 PropCheck stateful properties and Rust NIF at 6.4M events/sec. ACM SIGPLAN Erlang Workshop 2026 at ICFP paper submitted. - nx_vulkan — Vulkan GPU tensor backend for Nx; only known production GPU compute path for Elixir on FreeBSD. - zed — ZFS-plus-Elixir declarative BEAM deploy tool with Bastille jail-orchestration adapter live-verified on FreeBSD 15 Contact: io@octanix.com — github.com/borodark — Detroit, MI, USA.

Software Mansion
Elixir consultancy and open source maintainers, building real-time systems for clients and the ecosystem.
400+ person consultancy that has been working with Elixir since 2017 and invests heavily in the ecosystem's open source. We're the people behind Membrane, Popcorn, and LiveDebugger – so we know the ecosystem from the inside out. Our work covers the full range of what Elixir can do: web development with Phoenix and LiveView, real-time applications with WebRTC, multimedia pipelines with Membrane Framework, AI-powered audio and video processing, distributed systems, and low-level integrations with C, C++, and Rust. We also work on Elixir-in-the-Browser and offer team augmentation for companies already running Elixir in production. If you're building something serious with Elixir, we've probably done something close to it.
