About the project

Ariadna is a nationwide research panel that gathers Poles’ opinion on various topics related to everyday life. Respondents receive points for completed surveys, that can be exchanged for interesting rewards or for charity purposes.


Our task was to prepare the specification for the current system, optimize a large database, create a new system with refreshed and modern look, along with streamlined invitations sending process (over 1.5 million e-mails per month).

We started our work with code analysis of several company applications. Then we prepared the specification of the current application, which helped us to create a new one for the updated survey system. Thanks to this, we’ve managed to optimize and reduce database size, which has reached an enormous size over the years.


We started work on the new application version by defining website goals, writing down the most important functions and designing mockups. With prepared screens our graphic designer has created a modern and comprehensible website, which is fully responsive at the same time.

New application

Having an extensive specification available, we developed a new version of the survey system. We built the application based on PHP 7 using the latest version of the symfony framework. The creation of a new research panel was a big challenge, as the application consists of three separate, complex programs, which are:

1) Surveys system, that enables to conduct CAWI research.

2) E-commerce, that enables to order prizes with earned points.

3) Administration panel for employees.


The main requirement set by the client was to adapt application and database to the new requirements of GIODO / RODO. In addition to advanced work to secure personal data in the database, we have introduced a number of security solutions.

Example: the application checks where an employee is logging in from. When logging in from outside the office, ones must enter the code received by SMS.

E-mail platform

Ariadna sends over 1.5 million e-mails monthly. Our task was to optimize sending invitations process - both when it comes to the mail server and the program itself. Code refactor has speeded up mailing process by more than 4 times!

Servers administration

Our administrator has analyzed current server environment and and based on this prepared a new one that is more suited to the application of this size. This significantly improved application’s speed and decreased server costs.
