What it is

What you are actually getting.

Maintenance is where most products die slow. We provide ongoing engineering care so your live application keeps getting better instead of slowly worse.

The result XpansionIT delivers for Web Application Maintenance.

Who it is for

Is this the right fit for you?

This is a good fit when

  • Your team has shipped the product but no one has bandwidth to keep it healthy.
  • Security patches, dependency updates, and performance regressions are piling up.
  • A experienced engineer left and the system is degrading without their knowledge.

You probably do not need this yet if

  • You have an in-house team already covering maintenance.
  • Your product isn't live yet - it needs building first.

How it works

A clear path from first call to launch.

  1. 01

    Onboarding deep-dive

    Two weeks of system immersion: architecture, runbooks, common failure modes, deployment topology. We can't help if we don't know the system.

  2. 02

    Defined scope, named engineers

    Reserved experienced hours per month, named engineers, agreed-upon SLAs for security patches, performance issues, and bug triage.

  3. 03

    Quarterly health reviews

    Every quarter we audit dependencies, security posture, performance trends, and tech debt. The system gets healthier, not just less broken.

What you gain

The outcomes that matter to your business.

  • A product that stays secure, fast, and up to date.
