Service detailsNeed additional development capacity without hiring another full-time employee? DEVPLANX provides outsourced and subcontracted software development for new and existing projects – from individual features and API integrations to web systems, maintenance and modernization.

Not every software requirement justifies hiring another employee or engaging a large software house. Sometimes a project needs to move forward, a feature is stuck, an existing system needs improvement, or the internal team simply has more work than it can handle.
DEVPLANX provides outsourced and subcontracted software development for companies, software houses, agencies and businesses that need additional development capacity for clearly defined technical work.
Features, management systems, portals, dashboards, customer areas and business functionality for existing or new applications.
User interfaces, business logic, APIs, databases and server-side or client-side functionality.
Connecting existing platforms, CRM systems, external services, forms, automation tools and data sources.
Bug fixing, troubleshooting, feature changes and improvements without rebuilding an entire system unnecessarily.
Improving existing applications, gradually replacing outdated components and removing technical limitations that slow down future development.
Development can also cover the first version of a new product, from defining the initial scope to creating a working product that can be tested with real users.
Software companies and digital agencies do not always need to outsource an entire project. Sometimes they simply need another developer to take responsibility for a clearly defined part of the system while working within the existing codebase and development process.
DEVPLANX can work directly with your technical contact, handle defined development tasks and allow you to maintain your existing relationship and brand with your client.
You do not need to rebuild a system just because the previous developer is no longer available or the internal team is overloaded. We first review the existing code and understand the problem before deciding how the project should move forward.
The objective is to preserve what already works and change only what is actually necessary.
Depending on the project, development can include React, Next.js, Node.js, TypeScript, WordPress, React Native, Flutter, APIs, databases and existing software platforms.
The technology itself is not the starting point. The priority is understanding the existing system, the problem that needs to be solved and the safest way to integrate new development without unnecessary complexity.
We review the project, task, existing system and the technical or business objective.
We determine what is included, which systems or components are affected and what a completed result should look like.
Development is performed within the existing codebase, tools and development environment whenever practical.
The changes are tested to ensure they work correctly and do not create unnecessary issues elsewhere in the project.
You can start with one clearly defined task. If a larger need becomes clear, the engagement can be expanded based on the actual project requirements.
It is suitable for companies, software houses, agencies and businesses that need additional development capacity for a project, feature, integration or existing system without immediately adding another internal hire.
Yes. DEVPLANX can take responsibility for a defined part of a project while working within the existing codebase and process, allowing the software house or agency to maintain its client relationship.
Yes. We can review an existing codebase, fix issues, add features, build integrations or upgrade selected components without unnecessarily rebuilding the entire application.
Yes. The engagement can begin with one clearly defined task or feature before expanding the scope if additional work is required.
Depending on the project, development can include React, Next.js, Node.js, TypeScript, WordPress, React Native, Flutter, APIs, databases and existing software systems.
Pricing depends on scope, complexity, the condition of the existing codebase and the type of engagement. After an initial review, we can define the work required and provide an appropriate quote.
