RecommenderSystems
Recommender systems are intelligent software solutions that use artificial intelligence technologies to provide personalized recommendations to each user. These systems analyze large amounts of data—user actions and purchase history, behavior on the website, ratings, and preferences—and use machine learning algorithms to predict which products, services, or content will be most interesting for a specific person. Why is this needed? Personalized recommendations help keep the client’s attention, increase loyalty, and boost conversion rates: users more often find the products they need and make purchases when offered relevant options at the right time.
The world’s largest companies have been using recommendation algorithms to increase audience engagement for many years: from forming news feeds in Instagram and Facebook to generating music selections in Spotify or video suggestions on YouTube. Previously, such technologies were available only to giants with impressive budgets, but today even a mid-sized business can implement a recommendation system to gain a competitive advantage. Our company SKALAR helps incorporate these advanced tools into your infrastructure—from online stores to CRM systems. Recommender systems are the bridge between data and solutions, enabling businesses to thrive by anticipating customers’ needs before they realize them themselves.

Advantages of the SKALAR approach to personalization and analytics
At SKALAR, we adhere to a data-driven, analytical approach when developing recommender systems. Our solutions combine personalization, automation, and AI analysis for maximum efficiency. Here are the key benefits of our approach:
- Deep personalization. The system adapts to each user by considering their tastes, searches, and purchases, offering exactly what they need. Personalized recommendations boost customer satisfaction and encourage repeat sales, turning one-time buyers into loyal customers.
- Complete recommendation automation. Manual product selection is a thing of the past—algorithms automatically analyze the behavior of hundreds of thousands of users and instantly provide relevant suggestions. This saves time for your staff and ensures constant content updates that match the audience’s current interests, without human intervention.
- AI analysis and multi-criteria models. We employ modern machine learning algorithms capable of considering dozens of factors simultaneously. Our multi-criteria filters evaluate user behavior, product characteristics, sales trends, seasonality, and other parameters all at once. This AI-based approach reveals hidden patterns and offers highly accurate recommendations that cannot be achieved through simpler methods.
- Transparent logic and control. Despite the complexity of AI algorithms, the system’s underlying logic remains clear. We strive for transparency in recommendations, enabling businesses to understand why a particular product is being offered to a specific customer. Moreover, our architecture allows for flexible rule configuration—you can always set your own business conditions and constraints, combining intelligent suggestions with your expert knowledge.
- High performance and scalability. SKALAR’s recommender systems are designed to operate in real time, even under heavy loads. The system instantly updates recommendations when new data is received and can handle increases in audience size and product range. Performance and code optimization allow the solution to be integrated without significantly affecting the speed of your website or application, and the architecture easily scales as your business grows.
- Integration flexibility. Our solution seamlessly integrates with existing IT infrastructures—online stores, mobile apps, CRMs, or any other system. Flexible configuration means the recommender system can be adapted to your unique needs, from specific content formats to industry-specific requirements. We select the optimal technology stack for each project to ensure a seamless implementation and maximum efficiency.
Key stages of recommendation system implementation
Developing an effective recommendation system requires a step-by-step approach. We implement a full cycle of work — from analyzing your business requirements to supporting the final solution. Below are the key stages of implementing a recommendation system in collaboration with SKALAR:
Requirements and Data Analysis
At the first stage, we thoroughly analyze your business case: the goals of implementing recommendations, user profiles, and the specifics of your products or content. We audit available data (sales history, clients, product catalog, web analytics, etc.) and assess their quality and completeness. As a result, we gain a clear understanding of what tasks the system should solve and what data it will be based on.
Solution Modeling and Design
Next, our Data Science experts develop the concept of a recommendation model best suited to your needs. We choose appropriate recommendation methods (collaborative filtering, content-based, association rules, or a hybrid) and design the system architecture. A detailed project plan is created, outlining the algorithms and technologies to be used and how the system will integrate into your existing processes.
Model Development and Training
At this stage, we move on to practical implementation. Our engineers prepare the data for training (cleaning, feature engineering), develop algorithms, and write the code for the recommendation system. The model is trained on historical data, identifying patterns and dependencies. We run experiments with different models and parameters to achieve the best results — high recommendation accuracy and performance.
Integration and Deployment
The ready recommendation system prototype is integrated into your infrastructure. We set up real-time data transfer (e.g., new user actions or incoming products) and embed recommendations into your website or app interface (e.g., "You may also like" blocks on product pages). This phase involves close collaboration with your dev team or IT department for smooth deployment.
Testing and Fine-Tuning
After integration, we thoroughly test the system in a live environment. We evaluate the quality of recommendations and system performance (load testing, response time checks). A/B testing may be conducted to compare algorithms or display formats and determine the most effective setup. Based on test results, we fine-tune the model and algorithms to meet your KPIs (e.g., conversion rate or average order value).
Maintenance and Growth
Implementing a recommendation system is not a one-time project but a long-term improvement. We continue supporting the system post-launch: monitoring recommendation quality as data and user preferences evolve, and retraining models if needed. We can also expand the functionality — adding new types of recommendations, connecting more data sources, or optimizing algorithms to meet changing business goals. Continuous development ensures the system remains effective for years to come.

What recommendation systems we create
Every business is unique, and recommendations can take different forms depending on the industry. We develop a wide range of recommendation systems tailored to the client’s specific needs:
For Online Stores (E-commerce)
Solutions for online retail that recommend products based on customer behavior. These can include product blocks like "Similar to viewed", "Frequently bought together", personalized selections on the homepage, or "You may also like" sections. Such recommendations increase average order value and conversion, helping customers discover new products.
For Content Platforms
Recommendation systems for services with large volumes of content: online cinemas, music apps, news portals, educational platforms. We build algorithms that analyze content consumption (views, listens, likes) and suggest films, music, articles, or courses matching users’ tastes. This increases engagement: users stay on the platform longer and return for more.
Cross-sell Recommendations
Special models that suggest additional products or services complementing a selected item. For example, if a customer is buying a laptop, the system may recommend a laptop bag, software, or accessories. Cross-sell recommendations increase order value and improve user experience by offering everything in one place.
Upsell (Increasing Average Order Value)
Solutions aimed at suggesting premium or better alternatives to what the user is viewing. When a customer browses a product, the system may recommend a higher-tier model or one with enhanced features. Smart upselling increases average check and satisfaction by helping the user get a better-suited product they might have otherwise missed.
Personalized User Experience
Going beyond specific products, we implement personalization across a wide range of user experiences. This includes personalized email newsletters with product picks, smart push notifications based on preferences, or dynamic website content that adapts to each user (e.g., banners and offers relevant to their interests). Such personalization creates the impression that the service “knows” the user – significantly increasing brand loyalty.
