Support · Maintenance · Modernization

Application maintenance and support with SLA. And modernization while you keep running.

We take over the system your business runs on, even if another company built it: assessment, bug fixing, SLA-backed support, documentation and gradual legacy modernization, while operations keep running.

Talk to a specialist Build your system brief
SLA-backed support We take over legacy systems Incremental modernization PHP, Java, .NET, Node & more Monthly reports
Defined SLA and support
Priority levels, support channels and response times agreed in the contract, not left to goodwill.
Documented knowledge
Architecture, routines and decisions recorded in your repository. Your system is never hostage to one person, or to us.
Modernize without stopping
Modules replaced gradually, with planned windows and rollback, while operations keep running.
Proactive monitoring
Metrics, logs and alerts so we act before users open a ticket or the system goes down.
Signs it's time

When your system becomes a business risk

The situations that bring most companies to us.

The vendor is gone

The system runs your operation, but whoever built it has left and nobody knows what to touch without breaking something.

Bugs piling up with no priority

Tickets dragging on for weeks, no clear sense of what's urgent and no estimate for a fix.

Slowness and crashes

Frozen screens, jobs that take hours and instability right at peak times.

Unsupported technology

Old versions of the language, framework, database or operating system, with no more security updates.

Only one person understands it

All the knowledge lives in one person's head. If they take a vacation or leave, everything stalls.

Team stuck on maintenance

Your team spends the month firefighting and new features never leave the backlog.

Solutions

From urgent tickets to a modernization plan

One partner to maintain, stabilize, advise on and evolve your system.

SLA-backed support

Support by priority level, with response times and channels defined in the contract, ticket triage and follow-up until resolution.

Corrective/preventive maintenance

Production bug fixes, root cause analysis and preventive work such as reviewing scheduled jobs, cleaning up logs and checking backups.

Technical advisory & assessment

Review of architecture, code, infrastructure and risks, with clear recommendations so management and the tech team can decide next steps.

Legacy modernization

Modules replaced gradually using the strangler pattern: the new runs alongside the old until it takes over each part, with no big-bang rewrite.

Version upgrades

Upgrades of language, framework, libraries, operating system and database, with testing and a rollback plan.

Security fixes

Updates to vulnerable dependencies, fixes for pentest findings and good practices for access, passwords and data.

Method

From assessment to continuous evolution

First we understand and stabilize. Then we maintain with SLA and modernize in stages.

1Assessment

System assessment

Review of code, architecture, infrastructure, dependencies and ticket history to understand risks and priorities.

Risk and priority report
2Transition

Transition & handover

Access, environments and knowledge taken over carefully, with your current team or previous vendor whenever possible.

System documented and under control
3Stabilization

Stabilization

Critical bugs fixed, monitoring and alerts in place and backups verified before any bigger change.

Critical incidents under control
4Support

SLA-backed support

Tickets handled by priority, corrective and preventive maintenance, and deploys with testing and rollback.

SLA tracked month by month
5Modernization

Incremental modernization

Modules upgraded or replaced in stages, starting with what carries the most risk or the most return.

Less legacy at every stage
6Evolution

Evolution & monthly reports

Continuous improvements, technical backlog reviews and a monthly report on tickets, SLA and technical debt.

Decisions backed by data
Transparency

Know exactly how your system is doing

Support shouldn't be a black box. Tickets, SLA, technical debt and upgrades are visible in dashboards and reports. And because Devskin also works in DevOps, QA and security, the same team handles whatever comes up.

  • Tickets by priority, with response and resolution times tracked
  • Technical debt mapped and paid down gradually, alongside day-to-day requests
  • Dependencies and versions monitored, with alerts for known vulnerabilities
  • Every deploy logged, with automated tests and a rollback plan
  • A monthly report in plain language for management and the tech team

FAQ

Application maintenance FAQ

It depends on the size and criticality of the system, the stack, the expected ticket volume, the SLA levels and how much evolution and modernization is in scope. After the first conversation, your proposal includes a fixed monthly fee, with no end-of-month surprises.
Tickets are classified by priority, from a system that's down to a non-urgent change. For each level, the contract defines support channels, coverage hours and response times, based on how critical your system is. Every month you get a report on SLA compliance.
Yes, it's one of the most common scenarios. We start with an assessment of the code, infrastructure and risks, then run a planned transition of access, environments and knowledge, with the previous vendor whenever possible. Bigger changes only come after the system is stable.
In most cases, modernizing in stages is safer: the system keeps running while modules are upgraded or replaced one by one. A rewrite can make sense when the codebase can no longer evolve, and that recommendation comes out of the assessment, with risks and costs side by side.
The goal is to keep operations running. Changes happen in stages, are tested in staging and released in maintenance windows planned with you, with a rollback plan. When some downtime is unavoidable, as in certain database migrations, it's agreed on well in advance.
Fill out the brief or message us on WhatsApp. In the first conversation we learn about the system, its current situation and your priorities. Within 48 hours you receive a proposal with the engagement model, scope and pricing. Once approved, we start with the assessment and transition.
