Painting technology

We programmed robots painting car bodies of reputable brands

With the scale of, products and systems provided by one of the world’s leading suppliers services mainly for the automotive industry and the use of innovative solutions, the company was looking for a proven and experienced technology partner operating on an international scale. Thus collaboration with Sii was established.


Sii engineers are the authors, for example, of software and drivers to the transport systems for paint shops and software for robots installing sealing and applying paint on the bodywork of cars of the biggest brands in the world. In practice, these solutions have contributed not only to improved quality of production of vehicles, but increased the general performance of factories by running additional painting lines, automation and streamlined logistics. In addition to large-scale activities, the project itself was also technologically advanced, among others, in the use of Siemens or RFID products.

The company had been the first customer of the team, which gave the beginning of the Competence Center Engineering during past years. The projects of automated paint shops were the first realization in the field of automation that we process. It required us to build a unit with a new specialization from scratch. Skills required from engineers involved in these projects are not only connceted with PLC controllers commonly used in industry, but also with extensive knowledge of electrical engineering

Shopping in a modern form

We have built the largest group buying platform in Denmark

Sweetdeal is the largest group buying platform in Denmark, which is used every day by thousands of users. To increase sales and competitiveness on the Danish market, the owner of Sweetdeal, the company Berlingske Media, has decided to entrust Sii the creation of a product to strengthen relationships with customers by means of an innovative digital portal.


The new e-commerce platform is to serve primarily as a modern point of sale of goods enabling the company’s business partners to add new products to the offer in an easy and transparent way. Sii engineers were responsible for the entire process of building the system – from technical analysis, through the development of back-end and front-end, to testing and maintenance solutions. All this is based on the AWS cloud and Magento 2 platform – one of the most advanced solutions for online shops.


The commitment of the team with a wide range of competences and agile methodology of work has resulted in a platform responding to customer business requirements.

The customer is very satisfied with the results of the project, since the new platform will facilitate and optimize the sale of products, and improve cooperation with business partners. With the rapid migration of goods and users, we also managed to maintain business continuity of the company. For Sii it was another successful e-commerce implementation and a strong reference in the field of Magento, we also look forward to working in partnership with the client and are preparing for the implementation of the next project.

When it comes to human life

We co-create safety systems for the New York subway

More than 1.5 billion people a year use the New York subway. Their safety is in the hands of Polish engineers from Sii.


The LIRR project, carried out for the Canadian transportation company Bombardier, aims at improving the efficiency of fault diagnosis and safety of railways in New York. Sii specialists are responsible, among others, for the DMS system collecting data from different devices in the railway infrastructure of the Long Island Rail Road (LIRR) and the Metro-North Railroad. It is equipped with modules reporting and alarming of dangerous incidents associated with the movement of trains and processing information from monitoring devices. As a result, passengers can feel safe 24 hours a day, seven days a week, all year round.

One of our tasks is to check whether a train failure has been processed and recorded in the system and an alarm has been triggered. If the DMS does not work correctly, detecting failures on the railway line will be difficult and may lead to an accident. Human life is at stake, so we need to make sure that the system will respond properly in any problematic situation, even those that the client is not able to predict - says

Combination of fashion and innovation

We are developing a life cycle management system for sports products

One of the world’s largest manufacturers of footwear and sportswear was looking for a partner able to deliver tailored solutions. Sii engineers over the years have gained the trust of the clothing giant which has decided to entrust the company with the implementation of a key project – the creation of a product lifecycle management system.


In order to outperform the competition, the company entrusted Sii the creation of advanced technology solutions to support the design of completely new sports products.  The product lifecycle management system designed and delivered by Sii supports users in the process of ordering elements necessary for the production of shoes, and also allows to track the associated investment. With the new system programmers, designers and product managers can work on ideas from the initial concept stage, through prototype to the final product which is available on store shelves. Currently, all the tasks performed for PUMA are more than 50 engineers from Sii who in their work use a variety of technologies – from Java, the .NET and SharePoint to the Microsoft Business Intelligence.

Crucial for us is that Sii can provide high-expertise project teams within a relatively short time. Their engineers are experts in their respective fields and contribute to our projects valuable, goal-oriented input and a vast experience,

Robot in the role of tester

We designed an automatic touch screen testing system

Bombardier is one of the largest companies specializing in the manufacture and construction of aircraft, locomotives and rail, tram or subway cars. For more than 70 years it has been developing and improving the transport networks in the world.

One of the most important joint projects is the screen testing system. Sii engineers created a special robot prototype to automate touch screen control processes, for instance in trains manufactured by the client. The cooperation involved not only the design of its mechanical components, but also the implementation of the platform for communication with the client (PC), streaming audio and video as well as web interface implementation. As a result, users can now enjoy intuitive and efficient screens.

This task required us to join forces of specialists from several fields. Close cooperation of mechanics, electricians, electronic engineers, embedded programmers and web developers has resulted in the development of a complete solution from scratch. The project of this type was pioneering for Sii, but has not caused problems in implementation and we are pleased with its results.

Secure electronic payments wherever you are

We are building management systems for payment terminals and transaction services

Ingenico is a French company which provides technologies and products needed to support electronic transactions. With the support of Sii users can make secure cashless payments in stores and online.


The core business of Ingenico is based not only on the production of POS payment terminals, but also involves the development of complete payment software and related services, including systems for retailers. However, a completely new and challenging business goal set before the company was to design modern solutions to improve both planning as well as the production process and operation of the company service centers. The knowledge and experience of experts from Sii have resulted in the development of applications supporting terminal lifecycle management – from manufacture to implementation, e.g. in a store. At the same time planning and volume of production of equipment in factories were optimized. Ingenico customers now can enjoy secure payments and wider availability of services throughout the world.

The key to the project is the unique culture of team work and relationship with the client - fully based on trust and close cooperation. It created an unprecedented synergy and spirit of this group, which called itself COMMANDO TEAM. And this team has provided the first production version of the portal of critical importance for the client in record time of 6 months.
