The system of statistics for soccer matches

URL: https://www.parimatch.com/en/

Duration:  7 months 

Details of the project: For the one of leading sports betting companies in the CIS countries Parimatch (https://Parimatch.com), we developed a very complicated system of statistics based on the results of soccer matches. This statistical system permits generate reports in the context of soccer teams, players and judges.

The results of soccer matches we had to receive from one of specialized analytical agencies through REST API what was one of the biggest challenges in this project because the data provided by this agency had a lot of mistakes as well as we found a lot of errors in REST API. As a result we not only successfully completed development of this statistical system for Parimatch but we helped IT team of specialized analytical agency debug their REST API and fix most of errors in functionality of this REST API.

Rittal GmbH & Co. KG

URL: https://www.rittal.com/

Duration: 6 months 

Tangram Group of companies signed a sub-contract with one of the Canadian IT companies which acted as an official contractor of Rittal GmbH & Co. KG  Rittal is a German manufacturing company, part of the Friedhelm Loh Group  and at the same time Rittal is world's leading system supplier for enclosures, power distribution solutions, IT infrastructure, and software & services. Rittal is one of the top six fastest-growing German companies (Accenture), ranked 80th in the world's top market leaders from Germany. 
 

Details of the project: The main goal of this project was in migration of a huge list of Rittal's products from internal ERP system SAP Hybris into E-commerce platform Magento v2.*.

At the first stage of this project we planned the structure of PostgreSQL database and performed migration of products from the database of the internal ERP system SAP Hybris of Rittal into this external PostgreSQL database. The biggest technology challenge was in the migration of data from SAP Hybris because SAP Hybris does not have API or end customer did not provide any information about existing API.

At the second stage of this project we configured the set of complicated Magento plug-ins to successfully perform import data from the PostgreSQL database into Magento database.

We did not like the idea about migration from SAP Hybris into intermediary PostgreSQL database with future import into Magento database but for some reason it was a key requirement our customer (i.e. this Canadian IT company)  so we handled it.

Technologies: Magento v2.*, Zend Framework, LAMP (Linux, Apache, MySQL, PHP5), OOP, MVC, GIT, PostgreSQL, xHTML, CSS, JavaScript, DOM, XML, AJAX.
