I specialise in solutions within the Azure ecosystem: Azure Data Factory for ETL (SQL for heavy transformations, some python via docker/databricks), Data Lakes for storage, Azure SQL DBs for ready to use data and Power BI Semantic Models for analytics. I've both designed and developed such solutions from scratch, and I love the challenge of trying to figure out new things, from how to build integrations, to actually tackling them, automating every step, handling errors, documenting crucial undocumented information, etc.; the less I've got to work after handover the happier I am.
