// backend engineering studio

Backends built to stay insanely reliable.

We design, build and scale the server side of your product — in Elixir, Erlang, Java and Rust. Just rock-solid systems.

What we do

01

Backend from scratch

APIs, services and data layers designed for your product's real load — built right the first time, documented and tested.

02

Scaling & rescue

Inherited a backend that buckles under traffic? We diagnose, stabilize and re-architect systems without stopping the business.

03

Team reinforcement

Senior backend engineers embedded in your team — shipping alongside your people and raising the bar as they go.

// stack

The languages we live in

We deliberately specialize. A handful of languages, mastered deeply — not forty, known superficially.

Elixir

Concurrent, fault-tolerant systems on the BEAM. Our go-to for real-time and high-throughput services.

Erlang

The telecom-grade original. When nine nines of uptime is a requirement, not a slogan.

Java

The enterprise workhorse. Robust JVM services that integrate with anything and run for decades.

Rust

Memory safety without a garbage collector. Fearless concurrency for performance-critical services that can't afford to crash.

// AI-assisted

We use AI tools to move faster — scaffolding, tests and boilerplate ship in a fraction of the time. But we stay firmly in control of everything that gets generated: every line is reviewed, understood and owned by an engineer before it reaches your codebase.

How we work

1

Listen

A technical deep-dive into your product, constraints and existing code. No sales fluff.

2

Plan

A concrete architecture and roadmap with honest estimates — before any commitment.

3

Build

Short iterations, continuous delivery, tests as a default. You see progress weekly.

4

Run

Monitoring, on-call support and knowledge handover so your team owns the system.
