Web Application
Maintenance and Monitoring

Modern web applications are made up of multiple interconnected layers: backend services, frontend interfaces, APIs, databases, infrastructure, and a long list of third-party integrations. Each of these layers evolves on its own schedule, with its own release cycles, deprecation timelines, and security advisories. Keeping a web application healthy means keeping all of these layers compatible with each other while the ground shifts underneath them.

This is why web application maintenance is rarely a single task. A framework upgrade can trigger changes in dependencies, which can affect the database driver, which can change how the application talks to its infrastructure. A browser API update can break a frontend component that the backend depends on for a critical workflow. The work isn't just about applying patches. It's about understanding how a change in one layer ripples through the others and managing that change to keep the system stable.

We make sure your whole stack, from infrastructure to web application, stays stable. We specialize in maintaining both frontend and backend, specifically, Django on the backend and React on the frontend, and work with trusted partners such as Scalingo to ensure your infrastructure is also maintained properly.

Django is known for its long-term stability, maintainability, and backwards compatibility. This makes it a strong foundation for building business-critical applications. However, maintaining a Django application involves more than simply upgrading the Django framework itself. It also typically involves updating Python versions, third-party packages, database drivers, and the supporting infrastructure that the application runs on.

As a result, maintaining a production Django application requires familiarity not just with the framework but with its broader ecosystem, Django ORM behavior across versions, package compatibility, security advisories, deployment tooling, and the conventions of the specific codebase. If a business doesn't have dedicated Django developers in-house, a software support contract with a specialized Django agency is often the most practical way to handle long-term maintenance.

React powers the user-facing side of many modern web applications. It's a strong choice for building interactive, responsive interfaces, but the React ecosystem moves quickly. New versions of React, its supporting libraries, and the build tools around it can release breaking changes within weeks of each other, and what looks like a small update can quickly turn into work across many parts of the application.

Maintaining a React application means keeping it compatible with browsers, APIs, and backend systems, all of which also update regularly. Without regular maintenance, frontend applications gradually become harder to update, less stable, and more difficult to integrate with newer systems and services. Outdated dependencies can also introduce security vulnerabilities and compatibility issues that affect both reliability and user trust.

Although React is our preferred frontend framework, we also work with applications built on Vue, Stencil, and other modern frameworks, so existing systems don't need to be rebuilt to come under maintenance.

Logistics systems are typically of critical importance, and downtime or disruptions can genuinely be expensive, which is why software takeovers in this sector demand particular care and attention to detail.

We inherited Rhenus's existing logistics suite from a previous maintainer, then migrated the entire stack from a Kubernetes setup to Heroku without a single unplanned outage along the way.

That migration required upgrading the application's stack, rewriting parts of the codebase made outdated by those upgrades, and ensuring that the intricate data synchronization between the ERP and the dispatch server kept working throughout, without data loss or corruption.

The broader point is that taking over complex software written by someone else, stabilizing it, modernizing it, and keeping it running for the people who depend on it day-to-day is a core part of what we do.
