Independent data engineering.
Specialist expertise.
We help organisations build reliable data pipelines, improve performance and modernise their platforms. A boutique consultancy led by Roland Wenzlofsky, supported by a network of experienced specialists.
Based in Vienna, Austria. Working with international teams.
Start with the problem you need to solve
Your pipelines are unreliable
Build and improve ingestion, transformations and orchestration, with checks and documentation your team can maintain.
Data engineering and integrationYour workloads are slow or expensive
Identify the causes, agree a baseline and test changes against the workloads and operating constraints that matter.
Performance and cost optimisationYou need to choose a direction
Compare improving your existing platform with modernisation or migration. Make the assumptions and trade-offs explicit before committing.
Independent platform assessmentYou are planning a migration
Address business rules, data validation, performance and operational handover alongside the technical conversion.
Migration and modernisationExperience across source and target systems
Our published project accounts describe migration, research data engineering and enterprise reporting work. Each explains the delivery context; outcomes are specific to that engagement.
Retail warehouse migration
Teradata-to-Snowflake delivery with source-to-target reconciliation and knowledge transfer.

Vendor independence means that staying on your current platform and improving it remains a valid recommendation.

Work with Roland Wenzlofsky to define the challenge and delivery approach. We select specialists for the skills your engagement requires, with roles and responsibilities agreed before work starts.
Roland is the founder of DWHPro and author of Teradata Query Performance Tuning. His background includes enterprise data warehousing, performance tuning and platform architecture.
A clear path from discussion to delivery
- Define the problem. Start with a discovery conversation about your goals, platform and constraints.
- Agree the engagement. Put scope, responsibilities, deliverables, fees and acceptance criteria in writing.
- Deliver and hand over. Review progress, validate changes and document the work for your team.
For international projects, we agree working language, meeting times and time-zone overlap before the engagement begins.
