Quick answer
Keep live applications healthy after launch
Maintenance is not one activity. The recognised ISO/IEC 14764 model defines four types, and a healthy application needs all four. This service owns ongoing application health; technical support outsourcing owns the separate L2/L3 support-desk function.
| Type | What it means | Examples |
|---|---|---|
| Corrective | Fixing defects in live software | Bug fixes, hotfixes, resolving errors and crashes |
| Adaptive | Keeping software working as its environment changes | Dependency and Python/Django version upgrades, OS and cloud changes, API migrations |
| Perfective | Improving performance and usability | Query and performance optimisation, refactoring, small feature enhancements |
| Preventive | Reducing future risk | Security hardening, removing technical debt, improving tests and monitoring |
What we do
What is included in application maintenance and support
A live product needs more than tickets answered. It needs steady corrective work, proactive upkeep and senior engineering context that compounds over time.
01
Bug fixing & incident resolution
Corrective maintenance against agreed response times.
02
Security & dependency patching
CVE response, library updates and framework version migrations, including Python and Django upgrades.
03
Performance optimisation
Profiling, query tuning, caching and scaling fixes.
04
Monitoring & observability
Alerting, log analysis and proactive detection of recurring issues.
05
Small enhancements
The steady stream of minor features and changes a live product needs.
06
SLA-backed response
Severity-based response and resolution targets, with reporting.
Stack & delivery
Application support by framework
Support is delivered against severity-based SLAs you agree upfront, with a structured handover so the team can learn the codebase and reduce risk rather than merely react to tickets.
Python application support
Maintenance and L2/L3 support for any Python service or platform.
Django application support
Upkeep, upgrades and support for production Django applications and DRF APIs.
FastAPI application support
Maintenance for high-throughput FastAPI services.
Flask application support
Ongoing support for Flask applications and microservices.
Legacy Python modernisation
Safely upgrading and refactoring ageing Python and Django systems.
Adopted codebases
Structured onboarding to stabilise an inherited application that Uvik did not build.
How we work
How maintenance engagement works
Support is delivered against severity-based SLAs you agree upfront, with a structured handover so the team can learn the codebase and reduce risk rather than merely react to tickets.
1
Structured handover
Map the architecture, dependencies, operational risks and current maintenance backlog.
2
Define the SLA model
Agree severity levels, response targets, coverage hours and reporting.
3
Stabilise the application
Fix high-risk defects, patch dependencies and improve visibility.
4
Maintain and improve
Run the corrective, adaptive, perfective and preventive work as a predictable engineering cadence.
5
Scale coverage as needed
Increase or reduce monthly capacity as the roadmap, incidents and release cycle change.
Engagement
Maintenance support that holds application context
Maintenance and support
Use a flexible monthly engineering allocation for ongoing upkeep, incident response, upgrades and small enhancements.
Adopt an inherited application
Use structured onboarding when a prior vendor or internal team has handed over a Python, Django or web application.
Escalated support desk
For outsourced L2/L3 support as a product function, use the separate technical support outsourcing service.

Quick answer
Uvik Software’s rates are $50–$99 per hour depending on seniority, billed per engineering hour with no markups. Maintenance can run as a flexible monthly allocation scaled to your application’s needs.
| Severity | Example | Target response |
|---|---|---|
| S1 — Critical | Production down, data at risk | Rapid response; engineer engaged immediately within agreed hours |
| S2 — High | Major function broken, no workaround | Same-business-day response |
| S3 — Medium | Degraded or partial issue, workaround exists | Next-business-day response |
| S4 — Low | Minor issue or enhancement request | Scheduled into the maintenance backlog |

FAQ
Frequently asked questions
What is application maintenance and support?
Application maintenance and support is the ongoing work that keeps a live application healthy after launch: corrective bug fixing, adaptive dependency and version upgrades, perfective performance improvement, and preventive security and refactoring. Uvik Software delivers all four with senior engineers.
What are the types of software maintenance?
Four recognised types under ISO/IEC 14764 are corrective, adaptive, perfective and preventive. A healthy application needs all four.
What is the difference between maintenance and support?
Support handles incoming incidents when something breaks; maintenance is the proactive upkeep — patching, upgrading, optimising and hardening. Uvik Software provides both as one service.
Can Uvik Software maintain an application it did not build?
Yes. Uvik Software onboards existing codebases through a structured handover, then takes over maintenance and support, commonly when modernising legacy Python or Django systems.
How do you handle Python and Django version upgrades?
Version and dependency upgrades are adaptive maintenance. Uvik Software plans the migration, upgrades incrementally with tests at each step, and ships without breaking your delivery cadence.
How much does application maintenance cost?
Rates are $50–$99 per hour depending on seniority, billed per engineering hour with no markups, and can run as a flexible monthly allocation.
