# Software development & modernization

Move an existing application forward with new features, targeted improvements and a practical modernization plan.

A useful application does not always need a complete rewrite. We assess the current codebase, understand the problems holding it back and propose changes that support the next business goal.

A prioritized improvement plan and working changes that can be reviewed and released in manageable stages.

## What we can deliver

### Assessment and takeover

Review the codebase, dependencies, deployment process and known issues. Identify what can be reused and where changes carry risk.

### Features and migrations

Extend existing workflows, update frontend or backend components and plan technology migrations around the parts that need to change.

### Performance and reliability

Investigate slow paths and recurring errors, improve test coverage for important behavior and prepare clearer deployment and monitoring practices.

## Where this helps

### An inherited application

Establish how the system runs, restore a reliable local setup and agree on the first improvements.

### A backend that needs to evolve

Introduce new API behavior or migrate selected responsibilities while preserving the workflows users depend on.

### A product ready for its next phase

Add features and address technical debt so regular development becomes easier to plan and verify.

## From the first conversation to delivery

Start with access to the repository, environment documentation and the issues that matter most. Agree on a bounded first change before a broader migration. Experience includes participation in a PHP-to-Node.js/NestJS migration, frontend development and production maintenance within RESIMO / YSLAB.

## Questions about this service

### Can you take over work from another developer?

Yes, after assessing the codebase, access and deployment setup. The assessment determines the scope and what is needed for a reliable handover.

### Do you always recommend rewriting?

No. We compare targeted fixes, incremental migration and a rebuild against the actual business need, system condition and available budget.

### Do you offer ongoing support?

Yes. We can agree on a monthly development scope and support arrangements. Availability and response expectations are defined explicitly for the project.
