O|tech engineers data infrastructure for global enterprises. For 25+ years, we've been the team companies call when their data is broken and the stakes are high.

We specialize in three things:

Database Engineering — schema design, migrations, optimization, and automation. We build and maintain the systems your data lives on. PostgreSQL, SQL Server, cloud-native architectures.

Data Quality — deduplication, cleansing, enrichment, and the automated monitoring that keeps it clean. We've profiled and repaired datasets with hundreds of millions of records across FMCG, finance, logistics, and pharma.

CRM & Marketing Data — we make Salesforce, HubSpot, and custom CRMs actually trustworthy. Clean contacts, reliable segmentation, accurate reporting.

Our stack: PostgreSQL, SQL Server, Python, .NET, AWS, Azure. Increasingly: AI/ML for intelligent matching, classification, and anomaly detection.

Working with companies across Europe, the US, and the Middle East.

We're not a body shop and we're not a startup pretending to change the world. We're craftspeople who take data engineering seriously. Our people stay because the problems are hard and the culture respects expertise.
