Application maintenance and post-deployment support
At Yellows, we provide maintenance for web and mobile applications after deployment. We take care of system monitoring, ticket handling in line with SLA, security updates, backups, and minor development within a monthly pool of hours. We work in a transparent process based on a ticketing system and regular reporting, giving you control over the stability, security, and further development of your system.
What do you gain with Yellows support?
Stability and business continuity
Your application operates under constant supervision. We monitor system availability, detect irregularities, and react before a problem turns into downtime, user complaints, or business loss.
Security and up-to-date technology
We regularly update libraries, frameworks, and dependencies. We reduce risks related to vulnerabilities, outdated components, and uncontrolled changes in the environment.
Fast response to tickets
Each ticket receives a priority, an owner, and a response deadline. You know when to expect a reply and what the next steps in the support process look like.
Transparency of cooperation
We work based on clear rules, SLA, and a ticketing system. You have insight into statuses, activity history, used hours, and the scope of completed work.
Why is it worth entrusting application maintenance to Yellows?
At Yellows, we treat application maintenance as continuous system care, not just reacting to tickets. We combine post-deployment support with the experience of a development team, ensuring the stability, security, and further growth of your application.
Maintenance focused on the application
We focus on maintaining web applications, mobile applications, and business systems. We analyze errors, monitor system performance, handle tickets, and ensure application availability after deployment.
Support from a team that understands the code
Behind the maintenance is a team that understands the code, architecture, and software development process. This allows us to quickly diagnose problems, implement fixes, and develop the application without passing the issue between random contractors.
Safe takeover of system maintenance
We can take over the maintenance of an application created by another software house or freelancer. We start with a technical audit, review the documentation, and organize the ticketing process to safely assume responsibility for the system.
Regular reports and development recommendations
We regularly report completed work, tickets, and the condition of the application. We also provide technical, security, and development recommendations so that the system remains stable today and ready for future business needs.
When is it worth starting application maintenance?
The maintenance service is especially useful when:
-
the application is already running in production and supports important business processes,
-
the internal team does not want to handle ongoing support and incidents,
-
the system requires regular updates, backups, and security control,
-
you need predictable response times and a single ticketing channel,
-
you want to develop the system step by step without launching a separate project for every change,
-
you care about having a partner who will take responsibility for day-to-day care of the solution,
-
you want to organize ticket handling, monitoring, and reporting in one process.
What maintenance and post-deployment support include
-
Monitoring and availability
We monitor application availability, key environment parameters, and warning signals related to performance. Thanks to alerts, we can react quickly before a problem becomes visible to users.
-
Updates and security
We keep frameworks, libraries, and system components up to date. We implement security patches, analyze risks, and reduce the application’s vulnerability to failures and incidents.
-
Backup and data recovery
We create regular backups of the database and files. Maintenance also includes an organized system recovery plan after a failure, so downtime can be reduced.
-
Incident and bug handling
We receive, prioritize, and handle tickets related to bugs, failures, and functional problems. Each incident follows a clear process from submission to closure.
-
Minor modifications and system development
Within the monthly pool of hours, we carry out small changes, improvements, and corrections. This is a convenient model for companies that want to develop the system on an ongoing basis without launching a new project every time.
-
Ticketing system and reporting
We work in Redmine, so each ticket has a status, priority, and activity history. In addition, we prepare reports summarizing completed work, response times, and used hours.
How do we respond?
We operate based on clearly defined priority levels. This makes the ticket handling process predictable both for your team and for end users.
Critical
Response time: 2 hours
System unavailable or critical errors blocking operations
High
Response time: 4 hours
An important function is not working, but a workaround exists
Normal
Response time: 1 business day
Low-priority bug or functional question
Low
Response time: 5 business days
Improvement proposal or non-critical change

Our projects focused on stability, development, and long-term support
Centrum Terapii Dialog
Since 2019, we have supported the stability and development of a system that has handled over 110,000 patients, 700,000 online visits, and 540,000 payments.
Challenger
In the Challenger project, we provided continuous technological and product support, ensuring the stability, development, and smooth operation of the platform at every stage.
Why long-term support is cheaper than repair after a failure
A one-time deployment does not solve everything a production application requires continuous care. Companies choose the maintenance model for five specific reasons:
- Cost predictability - a fixed pool of hours instead of ad hoc projects priced under pressure.
- Shorter repair time - a partner who knows your system fixes incidents much faster than a new contractor.
- Security - dependency updates and vulnerability monitoring prevent gaps before they become incidents.
- Stable roadmap - minor development within maintenance hours, without launching a new project for every change.
- One owner - you do not have to look for “who is responsible for this” during a failure.
What should you know before starting application maintenance?
- audit of code, infrastructure, and documentation,
- list of risks and technical debt with recommendations,
- optional period of parallel work with the previous contractor,
- SLA launch with full responsibility.
At Yellows, we define up to 4 levels:
- Critical - up to 2 hours,
- High - up to 4 hours,
- Normal - up to 1 business day,
- Low - up to 5 business days.

What comes after MVP? Five decisions that determine scalability.
A working product and a working business are two completely different projects. Most founders think they are building both simultaneously - usually, they are only doing the first. This article documents five decisions that keep coming up in every post-MVP engagement: from market validation and technical debt, through architectural choices, to team composition and the technical roadmap.
