Why Yellows?

Among many IT companies, we try to show that we are a company that you can trust and trust. Trust is based on people, and in Yellows we carefully select our employees. In addition to technical competence, we attach great importance to the other aspects of the candidate's personality. Yellows is guided by values such as: reliability, responsibility, honesty and efficiency.

What programming technologies does Yellows use in their projects?

Currently, we mainly carry out projects in Java and PHP. We work with relational (Oracle, MSSQL, MySQL) and non-relational databases.

What is Agile?

Agile is so-called methodology of implementation of IT projects. We focus on providing visible business value to the client as soon as possible and as often as possible we consult the customer with finished application semi-finished products.

Which of the agile design methodologies is used by Yellows?

In our agile projects, we most often use the SCRUM methodology. What is the alternative to Agile? The classic methodology of implementing IT projects, namely Waterfall. It involves gradual progress through all stages of the project, from analysis through development to testing and implementation and finally to maintenance.

Which design methodology will be good for my project?

In projects with well-defined requirements (ie when the client knows what he wants to receive), the classic methodology, Waterfall, will work best. Thanks to this, we will implement the project as quickly as possible in accordance with functional requirements. However, if the requirements are not well defined (the client is not sure what he needs, or what needs to change over time), this will be a good reason to use the agile methodology.

Does Yellows carry out IT projects only for companies in Warsaw?

No. We work with all who need our help. Distance is not a challenge for us. We have programmers in our ranks in various parts of Poland. As part of our needs, we use means of transport as well as modern technologies. We have experience in working at a distance. Today, in the global world, we can implement a project for you even if your company operates in Hong Kong or Buenos Aires.

How much does it cost to write a mobile application for the Android, iOS or Windows platform?

It depends on the complexity of the designed application. The simplest solutions are possible to implement from several thousand zlotys. Large, complex mobile systems can be more expensive by orders of magnitude. You can get an approximate quote by filling out the form at the bottom of our website.
