Two disciplines, one team

What we do

We work across the whole delivery path, so the code and the platform it runs on are designed together.

DISCIPLINE 01v2.4 · WEB · APIS

Software development

Web applications, APIs and integrations built on proven stacks and written to be maintained.

  • Custom web applications and internal tools
  • REST and GraphQL APIs
  • Integrations with third-party and legacy systems
  • Modernisation of existing codebases
  • Automated testing and code review

DevOps

Pipelines, infrastructure and monitoring that make releases routine and outages rare.

  • CI/CD pipelines and release automation
  • Cloud infrastructure as code
  • Containers and orchestration
  • Monitoring, alerting and incident response
  • Cloud cost and performance reviews

How we work

A continuous, transparent workflow engineered to eliminate surprises.

  1. 01PHASE 1

    Understand

    We start with your goals, your constraints and the system you already have. No proposal before we understand the problem.

    Discovery & System Audit
  2. 02PHASE 2

    Plan

    A short written plan: scope, architecture, risks and milestones you can check progress against.

    RFC Spec & Milestones
  3. 03PHASE 3

    Build

    Small increments, reviewed and tested, delivered through an automated pipeline from day one.

    CI/CD Automated Staging
  4. 04PHASE 4

    Operate

    We deploy, monitor and keep improving. What we build, we can also run.

About

Four parts, one system

Quaternion is an independent software development and DevOps company based in Romania. We take on a small number of projects at a time, so the people you talk to are the people doing the work.

A quaternion has four components that act as a single number. We treat software the same way: code, infrastructure, delivery and operations belong together.

  • Clarity

    Plain language, written decisions, no surprises on scope or cost.

  • Quality

    Reviewed and tested code, reproducible infrastructure.

  • Ownership

    We take responsibility for what we ship, in production too.

  • Pragmatism

    The simplest solution that solves the problem and can grow with it.
