Here you can find an overview of my experience, technologies, and competencies.
I am a freelance Business Intelligence and Data Warehouse consultant with over 25 years of experience. I primarily focus on the backend—specifically data modelling, SQL, and various data platforms—where my goal is always consistent: to transform complex datasets into something the business can actually utilize, ensuring the result isn't just another fragile setup that only works on a Tuesday.
I have delivered solutions for organizations such as Nordea, BankData, and eBay, typically working in environments involving Oracle, Teradata, and SQL Server, where I assist in designing, developing, and optimizing data processes to ensure pipelines are reliable, transformation logic is well-documented, and data quality is not merely an ambition but a measurable and improvable metric.
My approach is both analytical and pragmatic, combining technical depth with business understanding, and I thrive best when given the opportunity to make complex systems more robust and simpler to manage, both for the developers involved and those who must rely on the solution in the future.
I utilize AI tools (such as ChatGPT and Gemini) for research, testing ideas, and drafting documentation, but I treat the output as suggestions rather than absolute truths, always validating it against actual data, existing documentation, and context, typically through test queries and the platform's own analysis tools.
The primary benefit lies in speed and structure, while the ultimate quality still depends on asking the right questions, identifying logical fallacies, and ensuring the solution aligns with governance and operational standards.
