The client needed to aggregate coupon and promotional data from a large number of websites across multiple countries, languages, and regional formats. Each source had different structures, anti-bot protections, and inconsistent data quality. Scaling the system while maintaining accurate merchant identification and coupon validity was a major challenge. On top of that, the distributed nature of the scrapers required robust monitoring to quickly detect failures and data anomalies.

Challenge

We designed and built a modular, scalable web scraping infrastructure capable of handling hundreds of independent data sources reliably. The system was developed with a standardized data model, shared utilities, and templated scrapers to accelerate onboarding of new websites. Advanced monitoring and validation mechanisms were implemented to ensure data quality and system stability. The result was a resilient, production-grade scraping platform with predictable performance and streamlined maintenance.

scraping-platform

Solution

The system is built around a modular scraper architecture, where each website is handled by an independent, purpose-built scraper while sharing a common core. This approach allows new sources to be added quickly without affecting existing ones and keeps maintenance isolated and predictable. Shared utilities and standardized data outputs ensure consistency across all scrapers, even when dealing with highly diverse site structures and anti-bot measures.

scraping-platform-key-feature-1

Modular Scraper Architecture

To maintain high data accuracy at scale, we implemented a multi-layer validation system that checks merchant identity, coupon relevance, and data consistency early in the pipeline. Automated mismatch detection prevents invalid or unrelated coupons from entering the database, while prioritized source logic improves merchant resolution. These safeguards significantly reduce noise in the dataset and ensure reliable, production-ready data.

Data Quality & Validation System

A comprehensive monitoring framework continuously tracks scraper performance, data yield, and system health across the entire network. Automated alerts detect issues such as zero-yield scrapers, build failures, domain mismatches, and data anomalies in real time. Detailed, context-rich notifications allow the team to react quickly, minimize downtime, and keep the platform running reliably at scale.

Finansi.bg faced the formidable task of developing a platform that could efficiently extract and present critical financial data from a vast and diverse set of documents. The primary challenge was dealing with inconsistently structured data across __2 million documents__, where not all pages held relevant information. This required a sophisticated solution to accurately sift through the noise and extract only the most pertinent data. Additionally, the platform needed to maintain high Google rankings, deliver exceptional site speed, and ensure a seamless user experience across all major browsers, all while controlling costs in processing and managing this extensive data.

To address these challenges, we employed a data-driven approach leveraging __advanced AI__ and __data processing tools__. We integrated a monolithic architecture using Laravel and employed AI-driven data processing to efficiently manage and categorize the vast datasets, which included over __2 million records__ in the document database.

Key technologies included __Retrieval Augmented Generation (RAG)__ for enhanced data retrieval and __VoyageAI__, which provided superior results compared to traditional __OpenAI embeddings__. These tools, combined with __Azure OpenAI Service__ for deploying and scaling AI models and __ChromaDB__ for vector-based data retrieval, allowed us to streamline the process of extracting, organizing, and analyzing financial information with unprecedented accuracy and efficiency.

Finansi case study solution

By using __VoyagerAI__ and __ChromaDB__, we automated the extraction of key financial data from over half a million documents, significantly reducing manual effort and ensuring high accuracy. An entire pipeline was developed __to sanitize and normalize the data__, which was then processed by multiple algorithms to produce standardized outputs. 

Throughout the process, __error detection algorithms__ flagged documents or pages for manual review, ensuring the highest level of data integrity. Out of all processed documents (__over than 2 million__), __fewer than 8k__ required human intervention, highlighting the efficiency and accuracy of the automated system.

Onno Plus needed to rapidly scale its operations while managing an increasing volume of leads, clients, reviews, and legal workflows across multiple platforms. Their existing systems were fragmented, with sales, support, and operations relying on separate tools that didn’t communicate effectively. 

This made it difficult to track performance, automate processes, and scale efficiently. The company required a single, extensible platform that could unify teams, automate repetitive work, and support continued growth without operational bottlenecks.

Lexis Solutions built an AI-first CRM platform that automated key workflows across sales, account management, and legal operations. AI-powered tools analyze review data, assist lawyers in generating review removal requests, and leverage historical case data to improve accuracy and speed. Automated review scraping continuously feeds structured data into the system, enabling smarter prioritization and faster decision-making.

__Pricerobot__ set out to build a real-time insurance comparison platform that enables users across Scandinavian countries to find the best car and home insurance deals on the market. The core challenge was extracting accurate pricing and product data from multiple insurance providers, each with unique business rules, technical implementations, and security protections.

The system had to operate under strict performance constraints, returning normalized and comparable insurance offers within approximately 2 minutes and 30 seconds per request. At the same time, provider websites frequently changed flows, introduced new security mechanisms, or applied aggressive anti-bot protections. The challenge was to design a flexible, resilient system that could adapt to these variations while maintaining speed, reliability, and data accuracy at scale.


Lexis Solutions designed and implemented a modular, adaptive web scraping and automation platform tailored specifically for large-scale insurance comparison. Each insurance provider was isolated into its own dedicated actor, ensuring changes or failures in one provider would not impact others. A centralized API layer orchestrates requests, validates inputs, applies provider-specific configurations, and aggregates results into a unified response.

The architecture was optimized iteratively. Initial browser automation ensured stability and fast delivery, while performance-critical providers were later migrated to direct HTTP-based implementations for speed. Advanced handling of security mechanisms, captcha-solving integrations, and dynamic proxy strategies ensured consistent execution within strict time limits. This approach resulted in a scalable, maintainable system capable of evolving alongside constantly changing insurance provider platforms.
