ZTABS builds AI data pipelines for Berlin businesses — ETL/ELT, feature stores, and ML data infrastructure. DSGVO compliant, German hosted, enterprise-grade.
AI data pipeline development in Berlin serves German businesses building the data infrastructure that powers machine learning — from data ingestion and transformation through feature engineering, model training pipelines, and real-time inference serving. Berlin's data pipeline context combines Germany's strict data protection regime (DSGVO requiring privacy-by-design in every pipeline), a mature enterprise data landscape (SAP, legacy databases, complex ERP ecosystems), and a growing AI adoption curve where the bottleneck is not algorithms but data quality, availability, and governance. Data pipelines in Germany: Berlin enterprise context. DSGVO: DSGVO fundamentally shaping pipeline architecture — every data transformation, copy, and storage location needing legal basis. Data minimisation, purpose limitation, and storage limitation requiring pipelines that process only necessary data, for specified purposes, and delete when no longer needed. German DPAs actively auditing data processing activities. Data quality: German enterprises sitting on vast data but struggling with quality — SAP systems containing decades of data with inconsistent formatting, legacy databases with undocumented schemas, and departmental spreadsheets holding critical business logic. Silos: German Mittelstand and enterprise having significant data silos — ERP, CRM, production systems, and department-specific tools rarely connected. AI requiring cross-functional data that pipeline engineering must deliver. Real-time: increasing demand for real-time AI — fraud detection, recommendation engines, and operational AI needing streaming data rather than batch processing. Kafka and event-driven architectures replacing nightly ETL batch jobs. Governance: German data governance expectations being high — Datenkatalog (data catalogue), Datenherkunft (data lineage), and Datenqualitätsmanagement (data quality management) expected in enterprise data infrastructure. Hosting: German data residency — AI training data needing to remain in Germany or EU, with clear hosting in AWS Frankfurt, Azure Germany, or German data centres.

Manufacturing / Data Engineering / AI / Berlin
A German manufacturing company (Berlin headquarters, 3 factories in Germany — automotive components, 2,800 employees, EUR 380M annual revenue) needed AI data pipelines to enable predictive maintenance, quality prediction, and demand forecasting AI. (1) Silos: manufacturing data trapped in 14 disconnected systems — SAP ECC (ERP), MES (Manufacturing Execution System) per factory, SCADA (process control), QMS (quality management), WMS (warehouse), PLM (product lifecycle), CRM, and departmental tools. Access: data scientists spending 80% of time finding and preparing data — only 20% on actual model development. Inconsistent: same data field having different names, formats, and meanings across systems (e.g., "material number" stored differently in SAP, MES, and QMS). History: 8 years of manufacturing data (2.4TB) across systems — valuable for ML but fragmented and poorly documented. (2) Quality: data quality preventing reliable AI. Missing: 15% missing values in critical sensor data — sensor failures, network issues, and logging gaps. Delay: data arriving with variable latency — some real-time (SCADA), some hourly (MES), some daily (SAP batch). Format: inconsistent formats — timestamps in 3 different time zones, measurements in mixed metric/imperial, and German number formatting (comma as decimal separator). Duplicates: duplicate records across systems — same production order appearing in MES and QMS with slightly different data. (3) Scale: data volumes exceeding current infrastructure. Sensor: 2,400 IoT sensors across 3 factories generating 50 million data points daily — current infrastructure unable to process in real-time. Growth: sensor deployment expanding — new production lines adding 800 additional sensors. Batch: nightly batch processing taking 14 hours — results stale by morning. Real-time: AI models needing real-time data — predictive maintenance requiring sub-minute sensor data freshness. (4) DSGVO: employee-related manufacturing data. Worker: production data containing employee information — shift assignments, productivity metrics, and quality records linked to individual operators. Betriebsrat: Betriebsrat (works council) requiring clarity on how employee production data is used in AI — co-determination rights per BetrVG §87. Anonymisation: AI models needing production context but not individual employee identity — requiring anonymisation/pseudonymisation in pipeline.
We built an AI data pipeline platform over 10 weeks — unifying 14 data sources for ML. (1) Data ingestion layer: connecting all sources. SAP: SAP CDC — real-time change data capture from SAP ECC using Debezium, streaming production orders, inventory, and master data changes. MES: MES integration — connecting to 3 factory MES systems via OPC-UA and REST APIs, normalising data models across factories. SCADA: SCADA streaming — Apache Kafka ingesting 50 million daily sensor data points from 2,400 sensors via MQTT bridge. Quality: QMS integration — quality measurement data extracted and normalised from quality management system. Batch: batch sources — PLM, WMS, and CRM data extracted via scheduled pipelines with incremental loading. (2) Data lake and transformation: unified data platform. Lake: data lakehouse — Delta Lake on AWS S3 (Frankfurt region) providing unified storage with ACID transactions. Bronze: bronze layer — raw data from all 14 sources stored as-is with metadata tagging. Silver: silver layer — cleansed, deduplicated, and normalised data with consistent naming, timestamps (UTC), and units (metric). Gold: gold layer — business-ready datasets and ML feature tables optimised for specific AI use cases. Transform: dbt transformations — documented, tested SQL transformations from bronze to silver to gold. Schema: schema registry — Apache Avro schema registry ensuring data contract compliance between producers and consumers. (3) Data quality: ensuring reliable AI data. Profiling: automated profiling — Great Expectations running data quality checks on every pipeline run. Checks: 420 data quality rules — completeness, accuracy, consistency, and timeliness checks across all data sources. Alerting: quality alerting — PagerDuty notification when data quality drops below threshold. Repair: automated repair — common quality issues (missing values, format inconsistencies) automatically remediated with documented rules. Lineage: data lineage — Apache Atlas tracking data from source through every transformation to AI model consumption. (4) ML feature store: powering AI models. Feature: Feast feature store — centralised feature engineering for predictive maintenance, quality prediction, and demand forecasting. Offline: offline features — historical feature computation for model training (aggregations over days, weeks, months). Online: online features — real-time feature serving for production inference (latest sensor readings, current production state). Consistency: training-serving consistency — same feature definitions used for training and inference, preventing training-serving skew. Catalogue: feature catalogue — self-service feature discovery for data scientists with documentation and quality metrics. (5) DSGVO and governance: compliant data infrastructure. Classification: data classification — personal data, sensitive data, and non-personal data classified across all pipeline stages. Anonymisation: anonymisation pipeline — employee identifiers pseudonymised/anonymised before data reaches ML training datasets. Access: role-based access — data access controlled per classification level and user role. Retention: automated retention — data retention policies enforced automatically per German regulatory requirements (GoBD for financial, specific rules for production). Betriebsrat: works council compliance — data processing documentation provided to Betriebsrat, anonymisation approach approved, employee data usage transparent. Audit: audit logging — complete audit trail of who accessed what data, when, and why.
