Tremend designed and built for ING Bank a complex card linked loyalty solution, intended as a powerful marketing tool that allows merchants to target very specific client segments (using bank’s demographic and transactional data) to deliver promotions.



From a technological perspective, the system had to deliver real time filtering with sometimes more than dozen criteria over hundreds of millions of transactions for millions of users.


A NoSQL environment was the most suitable candidate for this task and ElasticSearch emerged as a winner due to its high performance, almost SQL like capabilities to be queried.



Partnering with bank’s architects, Magento has been chosen as the best fit to replicate the shopping process that happens behind the scene. Significant customizations of the open source platform were required to pass security auditing and penetration testing. Since the system is real time with zero caching, Magento’s bootstrap process was dramatically improved in a concentrated effort that resulted in amazing response times.



Building Bazar solution from scratch, using a dedicated Scrum team, Tremend helped ING turn its ambitious ideas into a highly scalable platform that successfully serves bank’s clients. From a technological perspective, the highly available filtering engine based on ElasticSearch became a critical tool within the bank’s ecosystem, being adopted in other solutions and departments.
