The developers who are there when your team isn't.
Skip the months-long search for a developer. We take over your legacy system and are ready in 2 weeks. You don't have to freeze features or wait months for results.
- 19 years of web development
- 60+ projects delivered

Until your system is looked after again
Post the job, screen applicants, wait out notice periods, onboard.
First an honest assessment, then ongoing development alongside day-to-day business.
Time to fill IT roles in Germany: Bitkom 2025
Does this sound familiar?
You don't need to recognize all of them. Two or three of these already cost a lot of money over time.
The role has been open for months
The job ad is live, but the right applicants aren't coming. Every month without a developer makes the backlog bigger.
Your only developer is out
They're sick, have resigned or are on holiday, and suddenly operations stall. All the knowledge was in their head.
Nobody dares to touch the code
The codebase has grown over the years. Nobody fully understands it anymore, so nobody changes it.
Every update is scary
Even small changes can break something nobody expected. So nothing gets changed at all.
Updates have been postponed for months
Nobody internally feels responsible. Every month the update gets bigger and more expensive, and new security gaps appear.
The business is waiting on IT
The feature wish list keeps growing because there's no internal capacity. Ideas stall, and customers wait.
Agencies want long contracts first
Before anyone even looks at the code, you're asked to commit for months without knowing whether the collaboration will work.
You don't know how bad it really is
Is the software stable, or is it just waiting for the next outage? Without an honest assessment you can't decide what comes next.
It doesn't have to take that long
The gap can be closed in 2 weeks, not 8 months.
Agencies and recruiters earn money from placements, so a long hiring process doesn't bother them much. We start right away and work on your system while you take your time finding the right hire.

What it feels like afterwards
This is what it looks like once the points above are solved.
The gap is closed
Work keeps moving even while the role is open. You can take your time finding the right hire.
No standstill when someone is out
Knowledge no longer lives in one head. If someone is out, operations keep running.
The code makes sense again
The code is cleaned up and documented. Even a new developer finds their way around quickly.
Changes without the stomach ache
Automated tests protect what works today. New features ship without breaking something elsewhere.
Your software is up to date
Updates land regularly and are tested first. Known security issues are closed.
The business delivers again
Feature requests get built instead of gathering dust. IT is no longer the bottleneck.
You stay flexible
You start with a short assessment and then decide whether and how to continue.
You know where you stand
An honest assessment in plain language: what's fine, what's risky and what comes first.
How we work
Four steps, from the first look at your code to software that runs well again.
1
Assessment
In 1 to 2 weeks we look at your software and tell you honestly where it's stuck and what comes first.
2
We join in
We start working right away and don't need weeks of onboarding.
3
Build and clean up
New features ship while we clean up in the background and install updates.
4
Happy end
Your software runs reliably, makes sense again, and you get regular reports in plain language.
What we offer: interim development for PHP and JavaScript
It starts with a short sprint. Afterwards you decide whether and how to continue.
Code Readiness Sprint
1 to 2 weeks
An honest assessment of your software. It's worth having even if you don't continue with us.
- Codebase review
- Prioritized list of problems
- Quick fixes where possible
A developer for as long as you need
ongoing
We take over development with a fixed monthly budget of hours, until the role is filled or for the long run. You get something like an interim head of technology who takes full ownership of the project.
- Ongoing development
- Modernization without new features having to wait
- Full project ownership
Updates as a service
monthly or quarterly
Your software stays current, and nobody internally has to take care of it.
- Fixed update cycle
- Testing included
- If an update breaks something, we fix it
Sprint result not useful? We'll rework it at no extra cost.
Who it's for
Do you recognize one of these situations? Then we can help.
Companies without their own developer
Your software is business-critical, but nobody in-house can keep developing it.
Teams with a single developer
All the knowledge depends on one person. If they are out, everything stops.
Companies with an open developer role
Hiring takes time, but the work still has to move forward. We bridge the gap until the right person is found.
Grown PHP and JavaScript systems
Symfony, plain PHP, React or Next.js: often in use for many years and never properly cleaned up.

What an Unfilled Developer Position Really Costs Per Month
An open developer role does not just sit quietly on a headcount spreadsheet. It costs money every month, in delayed features, overtime, and deals that stall. Here is how to put a number on it.

Frequently asked questions
What does the Code Readiness Sprint cost?+
It depends on the size and state of your codebase. We estimate the effort in the intro call, and you get a concrete quote up front. We don't do long contract terms.
What if the sprint result isn't useful?+
Then we rework it at no extra cost. You should walk away with an assessment you can actually work with.
How quickly can you start?+
Usually within 2 weeks. Because we only work with a few clients at a time, we confirm availability in the intro call.
Do you work with our existing team?+
Yes. We fit into your processes and tools. If there's no team, we take over development entirely and document everything so someone else can take over later.
Which technologies do you work with?+
Our focus is PHP (mainly Symfony) and JavaScript/TypeScript (React, Next.js, Node.js), plus MySQL, PostgreSQL, Docker and CI/CD. We also take on older versions like PHP 5 or 7.
What happens if we fill the role after all?+
Even better. We hand over properly, with documentation and onboarding, so the new person can get productive quickly.
Your system won't wait 8 months.
In 30 minutes we'll figure out how we can help.
