Design the data architecture
We create a system that meets previously identified needs. Thanks to our expertise, you can be confident that your data architecture will be stable, efficient, and ready to support your business’s dynamic growth.
Dimension tables are essential for joining with fact tables to enable efficient query execution and optimal performance through structured relationships and indexing techniques.
Implement and migrate data and systems to the cloud
The next stage is the secure implementation of the new architecture and migration of your data, data storage, and company systems to the cloud. We complete these tasks quickly, minimizing risks and ensuring the shortest possible downtime.
Support management and optimize
We provide comprehensive support so that your data architecture operates smoothly and maximally supports business operations. We monitor performance, implement improvements, and optimize costs.
Understanding and reducing data redundancy is also critical for improving data management and optimizing query performance.
Discover our clients’ success stories
We helped Celsium build a data warehouse that reduced costs by PLN 180,000 per year
We integrated data from meters, SCADA, billing, and weather systems into a single data warehouse on Google Cloud Platform. We created advanced ETL processes, data quality control mechanisms, and dashboards in Tableau to support daily analysis of heat production and consumption.
The result? Meter failures detected in one day (previously one month), operational data updated three times a day, and significant savings thanks to heat source optimization and better demand balancing.
We built a modern data warehouse in GCP for PŚO
We helped Polski Światłowód Otwarty design and implement a scalable Data Lake architecture on Google Cloud Platform. We integrated 13 data sources, created automated ELT processes, access security, and a data model that serves as a single source of truth within the organization.
The result? Independence in reporting, rapid integration of new systems, readiness for future needs, and cost savings by eliminating on-premise infrastructure.
We helped AMS leverage data from DOOH media and maintain its position as a leader in outdoor advertising
We built a modern data ecosystem for AMS, a leader in OOH and DOOH advertising. We combined data from media, internal systems, Proxi.cloud, and CitiesAI to create a unified data warehouse in BigQuery with near real-time analysis.
The result? Data-driven targeting, campaign automation, better results for customers, and a stronger market position thanks to programmatic buying based on actual reach.
We helped Tutlo automate data integration and build a modern real-time ETL
In collaboration with the Tutlo team, we designed and implemented a data integration architecture based on serverless Google Cloud components. The system enables data synchronization from dozens of sources—including CRM—with full monitoring, CI/CD automation, and readiness for further scalability.
The result? A stable and flexible data ecosystem, ready for process automation, ML projects, and dynamic development of the educational platform.
We helped FunCraft forecast ROI and optimize UA budgets in the mobile gaming industry
We implemented a comprehensive BI solution for an American game studio, integrating data from Adjust, stores, and advertising platforms into the BigQuery warehouse. We built advanced dashboards in Looker Studio and predictive ROI models that enable accurate budget decisions—even with a long return on investment cycle.
The result? The FunCraft marketing team works faster, more efficiently, and with full control over their data.
Performance and cost issues?
We have a solution for that.
Too much data, too little performance
The data volume exceeds the infrastructure’s capacity, leading to system overload and longer query processing and analysis times.
Rising infrastructure costs
Non-optimized queries and a large amount of data, including duplicates and rarely used resources, strain the budget.
Company growth requires scalability
Your infrastructure is not ready for an increase in data volume, limiting innovation and planned expansion.
Systems require cloud support
A lack of a scalable data warehouse reduces the performance of data processing solutions used in your company.
