After the successful delivery of the main module of the discount management system for the Njuškalo classified ads portal, the second phase of the project was approached, which involved adapting the entire system to increased usage volume—during the technical analysis, a growth trend in the number of integrated merchants was observed, as well as increased dynamics in the change of commercial conditions in the market, which required additional upgrades to the existing solution. In accordance with the client's priorities, the project was implemented in a very short time frame, while maintaining delivery quality and stability of all existing functionalities, ensuring uninterrupted support for the client's business processes and their partners.
Functional context of the discount management system
The main task of the implemented system is to enable efficient and automated management of prices for products advertised on Njuškalo—the system encompasses all processes related to defined types of discounts, from promotional and seasonal to personalized and temporary reductions based on specific parameters such as product category, seller status, or ad duration. In addition to basic price management, the system takes into account rule priorities, dependencies between different promotions, and real-time dynamic data updates—this ensures that every portal user sees up-to-date, valid, and market-competitive prices without manual interventions, which is especially important in the dynamic environment of online advertising where prices change frequently.
Technical aspects of scalability and performance optimization
In order for the system to respond to the increased number of requests and growing data volume, it was necessary to carry out a series of technical optimizations—a key component was the redistribution of resources within the infrastructure, including database optimization through indexing and query restructuring, refactoring of key algorithms for discount calculation for faster execution, and the introduction of caching mechanisms at the feed level that reduce the load on backend services. In parallel, horizontal scaling of services communicating with the client's external systems was also carried out, to prevent the possibility of congestion or interruption during peak loads, for example during Black Friday promotions or other seasonal increased activities.
XML feed processing and validation as a critical functionality
One of the most important functionalities of the system relates to the preparation and sending of XML feeds containing data about products, associated discounts, and sales conditions—the system generates feeds according to the precisely defined client specification, with an emphasis on full compliance with technical and business rules that regulate ad display on the portal. Before sending to the client's server, all data goes through multi-layer validation that includes checking the XML structure, semantic correctness of data, and logical checks ensuring that illogical or contradictory records are not sent, for example negative prices or multiple promotions that cancel each other out. This approach minimizes the risk of errors and guarantees the accuracy of content available to end users, which is of direct importance for the portal's reputation and user satisfaction.
Integration with the public data processing system
After final validation, XML feeds are delivered to the client's external system, which further processes them and synchronizes with the frontend display on the portal—this phase requires a high level of reliability and time precision, as any delay or incorrect processing can lead to inconsistency between displayed information and the current state of prices and discounts. To avoid undesirable situations, mechanisms for monitoring and resending feeds in case of failure have been implemented, as well as reporting to system administrators about any suspicious or unusual activity through automatic notifications. The system thus creates a closed, self-monitoring loop between commercial conditions, technical delivery, and user data display, ensuring consistency at all stages of processing.
Delivery quality and focus on system stability
Special attention was paid to ensuring that all changes and upgrades are fully compatible with the existing system and do not negatively affect functionalities already in production—through the implementation of several test scenarios in real operating conditions, it was confirmed that the system reliably processes even multiple times larger data volumes than in the initial phase, while maintaining stability and responsiveness of all services. In addition to technical aspects, an important element of the project's success was continuous contact with the client for rapid validation of results and decision-making on the fly, which allowed the system to be optimized precisely according to actual business needs, not just technical assumptions that might deviate from practical requirements.
Strategic value of the system in the broader business context
Given that the Njuškalo portal represents one of the key places for online advertising and trade in the region, the reliability and scalability of the price management system have a direct impact on user experience and offer competitiveness—the developed solution is not just a technical tool but also a strategic mechanism for rapid adaptation to market changes. The ability to precisely control promotional activities, along with automation of a large number of operational tasks, significantly contributes to business efficiency for both the client and their commercial partners who daily use the platform to present their products and services—the system thus becomes an integral part of the digital trade infrastructure, ensuring stability, flexibility, and long-term business sustainability in an increasingly dynamic online environment.
