Scalable backends
High-throughput backend systems on Phoenix and OTP, using the concurrency model of the Erlang VM to stay responsive when traffic climbs.
Elixir Development
Elixir Development for Real-Time Systems That Stay Up
When thousands of users need live updates at once, most backends buckle. Elixir on the Erlang VM was built for exactly that moment, and so are the systems we ship with it.

What we build with Elixir
Concurrency, uptime, and scale are where Elixir earns its keep. This is the work we use it for.
Real-time applications
Live dashboards, chat, notifications, and collaboration features where updates reach every connected user instantly, without polling hacks.
Phoenix and LiveView apps
Rich, interactive web applications with LiveView, cutting out a whole layer of frontend complexity while keeping the experience fast.
Migration to Elixir
Overloaded backends moved to Elixir in phases, gaining fault tolerance and headroom without taking the product offline.
Your app should not slow down when traffic spikes
Tell us about your current stack and load profile, and we will show you where Elixir fits and what it would take.
Start a ProjectHow it works
How an Elixir project runs with us
- 01
Define the load
We establish what the system serves, how many concurrent users it must carry, and where the pressure points are.
- 02
Design for concurrency
Phoenix, OTP supervision trees, data flow, and APIs are planned around real traffic patterns, not optimistic averages.
- 03
Write clean Elixir
Idiomatic, well-structured code with concurrency built in from the start, peer reviewed by senior engineers.
- 04
Test under pressure
Performance, integrations, and failure modes are tested the way production will actually behave, including load and recovery.
- 05
Deploy and observe
CI/CD, monitoring, and alerting go live with the system, so process load and errors are visible from day one.
Why AIoptimix
Why teams pick AIoptimix for Elixir
Senior Elixir engineers
Engineers who understand OTP, supervision, and the BEAM, not developers translating object-oriented habits into a functional language.
Built for uptime
Fault tolerance is designed in with supervision trees and graceful degradation, because real-time products cannot afford blank screens.
Clean handover, no lock-in
Documentation, deployment guides, and a structured handover come standard. You own the code, the accounts, and the infrastructure.
Start small, scale freely
Begin with one engineer or a focused build, then grow the team as the product proves out. No lock-ins engineered to bill you.

Frequently asked questions.
What is Elixir best suited for?
Products that need many simultaneous users, live updates, and high uptime: chat platforms, live dashboards, collaboration tools, IoT backends, and SaaS products with real-time features. The Erlang VM underneath it has decades of telecom-grade reliability behind it.
Can you migrate our existing backend to Elixir?
Yes. We review the current system, identify which parts gain the most from Elixir, and migrate in phases so the product keeps serving users while the new architecture comes online.
Is Elixir overkill for a normal web app?
Sometimes, and we will tell you if it is. Elixir shines when concurrency and uptime are genuine requirements. If a simpler stack serves your product better, we recommend that instead: right tool for the product is how we work.
Do you handle the full delivery, not just backend code?
Yes. Architecture, Phoenix and LiveView development, database work, frontend integration, deployment, and monitoring can all be delivered by one team, with a fixed written scope and USD pricing.
