Monthly retainer

Senior ownership of your codebase: roadmap execution, incident prevention, architecture improvements and cost discipline, month after month.

Duration
monthly
Who for
Product teams that want ongoing ownership of their system, and agencies that need a white-label delivery partner.
How it starts
After the audit or the pilot. Sized to the work, no long minimum term.

What changes for youFewer incidents, more frequent releases, and a clear owner who answers when the phone rings.

What you get

  • Execution of the roadmap: upgrades, migrations and refactors, module by module
  • Incident prevention: monitoring, alerts, fixes before they become escalations
  • Architecture improvements and cost discipline
  • A direct channel to the engineer, not to an account manager
  • A short monthly report on what changed and why

Method

How we work

Four rules that have kept us away from failed rewrites and 3 a.m. incidents.

01

Incremental beats rewrite

We moved a production SaaS platform from a mixed PHP and Node.js stack to Symfony 7, with verified behavioral parity, while the product kept shipping. We recommend a rewrite only when the audit numbers actually support it.

02

Tests go in before the refactor

We document existing behavior, generate and verify tests, then change things. Nothing reaches production without the safety net.

03

AI orchestrated, human judgment

We use AI agents daily, including multi-agent setups, for tests, review, migrations and documentation. They compress delivery time. Architecture, decisions and accountability stay human, and we answer for every change that reaches production.

04

Boring on purpose

Clean architecture, small units, unexciting technology that keeps working. We write code as if someone else maintains it tomorrow, because that is exactly what will happen.
