Before AI can deliver results, the data has to be right

AI and analytics projects stand or fall on the quality of the data. When numbers contradict each other, platforms remain half-empty, and pipelines run without testing, even the best model won’t help.

We lay the foundation: integrated, quality-assured data that’s reliably available —operated in production rather than as a proof of concept gathering dust in a drawer.

Less Technology. Better Business.

Engineering That Makes a Difference in Production

Full-scale implementation instead of a pilot project

About 70% of our projects result in a fully operational platform—with tested code and senior engineers on board from day one.

Architecture Without the Clutter

Our Medallion Reference Architecture supports the use case with 20–30% fewer components—it’s lean, maintainable, and free of over-engineering.

Manufacturer depth without commitment

Certified on Snowflake, Databricks, Microsoft, and AWS, but with no commission—we recommend what your use case needs, never what’s best for our bottom line.

Costs from the very beginning

We incorporate FinOps from day one: tagging, right-sizing, and alerts typically reduce your cloud costs by 20–40% compared to standard practices.

Data Engineering Services: The Foundation of Analytics and AI

Data engineering services encompass the expertise and infrastructure that ensure your data is reliably available, integrated, quality-assured, and usable —including platforms, pipelines, modeling, and operations. They form the foundation upon which analytics and AI can be built in the first place, and are therefore almost always the critical path. As a data engineering consulting firm, we combine strategy, architecture, and tool selection.

Within Data Engineering Services, we focus on the data foundation—the bedrock. Our sister teams in Data Science, AI, Analytics, and Governance Consulting handle the models built on top of it, BI reporting, and comprehensive governance programs, so you get everything from a single source. There’s only one thing we deliberately avoid: pure tool licensing and reselling—this ensures our recommendations remain unbiased.

Data Engineering, Analytics, or Data Science—Which Comes First?

If your data isn't flowing reliably, data engineering is the first step. If the data is there but no one understands it, data analytics takes over. If you have data and reporting but are missing only the predictions, data science comes into play. In practice, these three often run in parallel —the data foundation remains the critical path.

DWH Consulting, DWH Services, and Data Integration—three specialized services

Three terms that are often used interchangeably actually have different meanings:

  • Data Warehouse Consulting: the conceptual side—modeling and architecture.
  • Data Warehouse Services: the implementation side—setup and operation.
  • Data Integration Services: the specific task of connecting source systems and consolidating data.

Whether ETL or ELT, data lake or lakehouse, data mesh or streaming—we classify these terms as needed. ELT dominates in modern cloud and lakehouse architectures, while ETL remains relevant in regulated or legacy scenarios.

Here's How We Build Your Data Platform

A data platform is not an off-the-shelf product. We build it using carefully coordinated components —from the initial assessment to ongoing operations—and deliberately choose the simplest architecture that meets the need.

Six interlocking building blocks

We deliver production-ready, scalable platforms rather than isolated proof-of-concepts. These six building blocks are interconnected:

  • Strategy & Assessment: Maturity Level, Target State, Prioritized Roadmap with Business Case.
  • Architecture & Design: Target architecture based on Lakehouse, data warehouse, or streaming; data model and security concept.
  • Platform Architecture: Cloud-native, with Infrastructure as Code, CI/CD, a data catalog, and observability.
  • Pipeline Development & Integration: heterogeneous sources, batch and streaming, with built-in quality checks.
  • Migration & Modernization: Moving a Legacy Data Warehouse to a Cloud Lakehouse—Low-Risk and in Phases.
  • Operations & Optimization: Run, SRE Mindset, FinOps, and Performance Tuning.

In our day-to-day work, we use Azure and AWS, Snowflake, Databricks, and Microsoft Fabric, Airflow and dbt, Kafka and Flink—the choice depends on your use case.

DWH Modernization: Replacing Legacy Systems Without a "Big Bang"

We’re phasing out Oracle, Teradata, and SAS in favor of cloud lakehouses—Snowflake, Databricks, or Fabric. Instead of a risky “big bang” approach, we’re using the Strangler Fig pattern with parallel operation: the old and new systems run side by side for a while, reconciliation tests ensure data consistency, and the cutover takes place step by step.

Data Integration: Reliably Connecting Heterogeneous Sources

SAP via OData, CDC, and BW extraction, plus Salesforce, ServiceNow, IoT telemetry, and legacy databases: Our Data Integration Services connect what belongs together. Our approach is always consistently robust—source profiling, a “CDC-first” approach wherever possible, binding schema contracts, and a quality gate before data flows to the destination.

When Building a New Home Is Worth It—and When It Isn't

Most projects start from one of four scenarios. AI or GenAI is planned, but the data isn’t ready—it lacks quality, integration, or a governed platform. A legacy data warehouse like Oracle, Teradata, or SAS is expensive, slow, and at the end of its lifecycle.

Data silos produce conflicting figures, and reporting loses credibility. Or a cloud migration is hampered by growing data volumes and increasing regulatory requirements—DORA, NIS2, and the EU AI Act are ramping up the pressure for traceability.

  • Building a new system is worthwhile if your current system is demonstrably at its limit, if several demanding use cases are on the horizon, or if data volumes are growing significantly.
  • We advise against this if the actual problem lies in data quality, ownership, or modeling; if only a single report is affected; or if, ultimately, you are simply looking for a new tool.

In the second case, it is often sufficient to optimize the existing system, set up a targeted data mart, or gradually modernize individual domains.

From the CDO to Executive Management

The decision to adopt a data platform usually involves several stakeholders—each with different priorities. We address each one with the argument that matters most to them:

CDO / Head of Data

Faster, more reliable data for analytics and AI, as measured by time-to-insight.

IT Management/CIO

Stability and manageable costs through an SRE mindset, automation, and FinOps.

Department

Finally, reliable data and self-service—no more waiting on hold with IT.

Management

Investment security through a clear business case, ROI, and cost of delay.

Four industries in which we excel

Through our own projects, we are familiar with the recurring data challenges and regulatory considerations in each of these industries. This saves time in the planning phase because your platform is built on proven models, and industry-specific requirements are factored in from the very beginning.

abstract-linen 2

Energy Industry & Utilities

Smart meter data, market communication, and time series processing on KRITIS-compliant platforms—with the rollout under the MsbG, these will become massive time series that place high demands on performance and governance.

Typical use cases: feed-in and load forecasts for solar and wind, grid utilization analyses, and asset monitoring. The higher the share of volatile generation, the more forecast accuracy and grid stability depend on reliable real-time data.

Manufacturing & Industry

Four Phases to a Productive Platform

We develop data platforms iteratively and with a focus on risk management—without a “big bang” approach and with an eye toward measurable results. Four clearly defined phases take us from the initial consultation through the proof of value to stable, long-term operation.

Phase 1: Diagnosis & Target State

In one to two weeks, we’ll talk with your stakeholders, assess your resources, current state, and maturity level, and refine your vision. The result will be a prioritized roadmap with a business case and initial quick wins—a clear roadmap instead of a mountain of concepts.

Phase 2: Architecture & First Breakthrough

During the architecture design phase (three to four weeks), we define the target architecture, tool selection, data model, and security and FinOps concepts. The PoC then runs an end-to-end process—including tests and a catalog—with the first run typically completed in four to six weeks.

Phase 3: Development & Integration

Over a period of three to nine months, we scale up to include additional sources and domains and migrate legacy systems in phases. Depending on the project, we work on a fixed-price basis, on a time-and-materials basis, with a dedicated team, or—most commonly—with a hybrid team, supplemented by south-shoring with senior management oversight.

Phase 4: Operation & Optimization

After go-live and hypercare, we can take over day-to-day operations upon request: Run, SRE mindset, FinOps, and tuning—either as a managed service or as part of the customer’s team. We are guided by hard KPIs—time-to-insight, pipeline reliability, data quality, cloud costs, and ROI.

For one insurer , the time-to-insight dropped from 11 to 2 days, reliability rose from about 90% to over 99%, and cloud costs fell by about 35%—even as data volume doubled.

Platforms currently in production

Our data platforms are integral to our customers’ day-to-day operations—across a wide range of industries, from the public sector to the energy industry and insurance.

In two weeks, you'll know where you stand

Before you invest, we provide clarity. Our Data Engineering Assessment delivers an assessment of your current state, a maturity level, and a prioritized roadmap—including a business case—in about two weeks, with minimal effort required from your team. You decide whether to use the results to guide implementation or to safeguard your existing systems.

Assessment & Maturity Level

We review the data landscape, sources, pain points, and existing platform.

Target Architecture Recommendation

Lakehouse, DWH, or streaming—the tool selection is made in a vendor-neutral manner based on an evaluation grid.

Business Case & Roadmap

Quick Wins, Cutover Strategy, and the Next Steps—with or without subsequent implementation.

Let's talk about your data foundation

Without a reliable, integrated data foundation, analytics and AI won’t work—it’s almost always the critical path to any data-driven initiative. If you lay a solid foundation from the start, you won’t have to spend a fortune later on data quality and migration.

This is exactly where we come in: as engineers who deliver platforms designed for productive operations— vendor-neutral, with FinOps, and a proven migration playbook.

Frequently Asked Questions About Data Engineering Services

  • Snowflake or Databricks—which platform is right for us?

    We decide this together using an evaluation grid rather than based on a preferred platform: dominant use cases, existing team skills, current cloud setup, data volume, latency, compliance, and cost patterns. We’re certified for both and aren’t tied to any commission—often, a combination of the two or Microsoft Fabric is the better solution.

  • How much does a data engineering project cost—and at what point does it pay off?

    We’ll kick off with a business case in about two weeks. The cost of delay and unoptimized cloud costs are usually more expensive than the project itself; built-in FinOps typically reduces cloud costs by 20–40%. Depending on the project, billing is either a fixed-price package or a time-and-materials model.

  • Can't we set this up ourselves in-house?

    You can—though doing it in-house usually takes twice as long. We provide proven templates and access to vendors, and hand over the platform fully configured so your team can continue managing it on its own.

  • How do you ensure data privacy and compliance in data pipelines?

    We incorporate compliance as a gate in the pipeline, not as a downstream audit. This includes quality testing with dbt, Great Expectations, and Soda; a data catalog with automated lineage; access control models using RBAC and ABAC; tag-based masking and PII classification; as well as GDPR-compliant pseudonymization and data erasure strategies. We factor in the Data Act, NIS2, and the EU AI Act from the very beginning.

  • How does data engineering fit into our AI strategy?

    AI is only as good as the data it’s based on. For GenAI today, even unstructured data—such as documents and texts—must be usable, classified, and tagged with lineage. That’s why we’re designing the platform from the ground up to handle both structured and unstructured data, ensuring the data readiness that models can rely on.
