At a glance#
Demir Technology is an Amsterdam-based data and AI consultancy. We operate at the intersection of Data Engineering, AI Engineering, and Data Science — building modern data estates on Microsoft Fabric and ontology-instructed AI systems that combine knowledge graphs with LLMs.
The work is delivered by Fatih Demir — Data Engineer, AI Specialist, and Microsoft Certified Trainer (2008–2024) with 25+ years across meteorology, cyber security, academia, and the modern data stack.
Based in the Netherlands, working with clients across Europe — remote and on-site.
Core focus#
Data Engineering & Microsoft Fabric. Expert in architecting unified data estates. Leveraging Microsoft Fabric together with Apache Kafka and Flink to build high-throughput ETL/ELT pipelines that ensure real-time data availability and governance.
AI & GenAI Engineering. Moving beyond standard models to design ontology-instructed AI systems — integrating knowledge graphs with LLMs to create semantic engines that understand business logic, not just process text.
Data Science. Applying rigorous statistical methods and machine learning to optimization problems, validated by Azure Data Scientist credentials.

How we work#
Pragmatic engineering — choosing the right tool for the job, not the most fashionable one. Clean, documented, testable code that your team can maintain long after the engagement ends.
- Flexibility — short sprints or long-term embedded roles
- Autonomy — hit the ground running, minimal hand-holding
- Transparency — clear communication, regular updates
- Quality — we don’t ship code we wouldn’t want to maintain ourselves
