About DS Stream

Warsaw is home to DS Stream, a consultancy of senior data engineers and data scientists that turns scattered company data into information that supports decisions. Its work spans data pipelines, cloud platforms, analytics and AI, and the firm says it is not tied to any single technology.

Pipeline automation and a managed Airflow service

The firm simplifies pipeline automation and scaling, so that clients can spend their effort on insight and strategy rather than on maintenance. It offers a managed Apache Airflow service, which takes the operational load off the client's own team.

Data engineering and cloud solutions

Data engineering turns disparate data into a dependable base for decisions, and cloud solutions support the platforms those pipelines run on. The company works with cloud infrastructure for the data and for the applications built on it.

Analytics, machine learning and generative AI

Advanced analytics and data science are combined with machine learning and generative AI, so that clients can build custom AI tools and support AI-driven business decisions. The firm says its specialists cover the full range from analysis to deployment.

MLOps for models in production

MLOps brings machine learning and DevOps practices together so that models move smoothly from development into production. Machine learning workflows are automated to improve efficiency and predictability, on a client's own infrastructure or in the cloud.

Case work across FMCG, telecoms and research

DS Stream built an AI-powered research platform for the longevity ecosystem, turning manual processes into real-time intelligence. For Lorenz Polska it worked on category management analytics in the fast-moving consumer goods sector. For Iliada.pl it automated resort package sales with an AI voice bot that the firm describes as the first of its kind in Europe, offering 24/7 multilingual service and instant bookings.

Sectors and senior teams

The firm says it works across FMCG, retail, e-commerce, healthcare, telecoms, finance and logistics for global brands, and that its engineers have more than 10 years of experience in machine learning, data science and generative AI.
