Senior developer from 29€ 22€

*Only until the end of October

Our speciality is to be the helping hand when a reliable professional is needed, at a fair price.

You have an extensive project? Do you want to concentrate on specific areas? You urgently need a developer? Native language project management is important to you?

With us you have found a reliable partner who offers a mixture of inexpensive hourly rates and high-quality work. Our business model is based on more than 25 years of agency and freelancer experience of the two company founders Klaus and Greg. We connect flexible Freelancertum with classical enterprise values.

What do we offer?

We offer individual developers or entire development teams, optionally including project management and testing on an agreed weekly hourly basis. (from 5h/week)

Unlike freelancer platforms, we offer comprehensive consulting and easy help and accessibility, especially when a problem occurs – just when it matters. All our freelancers have been extensively tested and proven themselves in projects.

We would be happy to advise you on the specialists you need and also evaluate the effort involved so that you have an overview.

Backend Development

We work with different frameworks and CMS – Laravel  is our favorite food. Otherwise we also like Yii, CodeIgniter, CakePHPO – we also like to develop extensions e.g. for Magento.

Frontend Development

From good old HTML to Bootstrap, Sass, LESS, Stylus, Vue.js, React or Angular, we got it. Marko, Milos, Ilya and co are looking forward to the task

Databases and more

Classical MySQL  is in our portfolio as well as the MongoDB or Elasticsearch. Otherwise we can run Bitbucket, Amazon AWS, PHPUnit, Jenkins …

Project management

New we take care of your complete project. From (Native-language) project management to pixel-perfect quality control. Your  project will be completed on time and within budget . Lesia, Robert and Marko are ready.

A fair model for modern web development

We offer two fair price models. The “team hour” model (37 until the end of October only 30 €), which is ideal if you want to outsource a project to us, or the “developer hour” model (29 until the end of October only 22 €), which is ideal if you need a good head for your team.

Do you need a project appraisal? We do this free of charge and without obligation. We estimate your project with min. and max. hours and the required developer type and create a proper white label PDF with our results. We can also add your logo so that you can send it directly to your customer. This is 1-2 days of work, which we give away for free 🙂

What previous customers say

The ratings come from a large freelancer platform.

How does the cooperation with us work?



The preparation

  • We will discuss your requirements with you, we will be happy to prepare a non-binding estimate.
  • Based on this, we present potential candidates to you who have the appropriate know-how and sufficient time.
  • Now we define a weekly target and a weekly limit of hours (e.g. Marko – weekly target 15 hours, weekly limit 17 hours) and the billing cycle (e.g. 14 days).

The start

  • You get your client access to “Hubstaff” where the working time including screenshots will be recorded
  • You make the first deposit. Our usual modality is advance payment of a cycle. We accept bank debit, Paypal, Payoneer and credit card.
  • The team or developer will contact you about coordination and set up the working environment.
  • The work starts. 

The workflow

  • With “developer hours” bookings you can now start assigning tasks to your freelancer.
  • In the context of “team hours”  bookings, your project manager discusses your wishes and takes care of the process from now on
  • For “Team Hours” bookings we hold regular (daily) Standup Meetings where you are cordially invited to participate. Furthermore, your PM will continuously present the work results to you and work out the next steps with you.

Unused / Limit hours and termination

  • If it should become apparent when reaching the weekly target that there is still work to be done, we ask if we should use the weekly limit. Limit hours will be charged in the next cycle.
  • Unused target hours are transferred to the subsequent cycle, the maximum transferable volume is 50% of a target week.
  • If we are responsible for the reason for the cancellation (illness..), the hours will be transferred without deduction. If the freelancer is not available in time, we will take care of replacement.
  • Cancellations are possible at any time, the contract ends at the end of the paid cycle. Unused hours will be reimbursed.

Why does it make sense to hire us?

because we only admit the best freelancers to our team, and because with us you have the security of a decent company.

How we find new people: We create tenders in various platforms. We receive about 20-40 applications in response to a call for tenders. The tender contains technical questions, approx. 50% are not answered here.

The remaining participants have to fill out a technical questionnaire, here too another 50% are omitted. Those remaining are invited to an interview with Klaus and Greg. In addition to know-how, punctuality, English level and general communication will be tested.

The 2-3 top candidates are tested with a small work task.2-3 If successful, a first job follows with a regular client (at a special price, the client is informed).2-3 If this job was successful and the new freelancer has proven in the long run that he works well, is punctual and reliable, only then can we be sure that he is also a good choice for you.

You need a field we don’t cover yet? Contact us, we will be happy to search for you.


We look forward to discussing your project with you.
