| Skill | How I use it and what for |
|---|---|
| SQL (T-SQL and PL/SQL) | Analytical queries with window functions and WITH clauses, and large stored procedures (over 8,000 lines) with loops, variables and parameters, on SQL Server (T-SQL) and Oracle (PL/SQL), so reports start from correct figures. |
| Power BI, DAX and Power Query | I build reports from scratch and reusable models, with DAX for the business logic and Power Query to prepare the data, so the business reads fast and trusts what it sees. |
| SAP BusinessObjects and SAP Analytics Cloud | I develop and maintain reports, manage development and production environments, run migrations and train teams, so corporate BI platforms keep running and stay governed. |
| SAP Data Services (ETL) | I load, integrate and transform data between systems, to feed models and reports with clean, consolidated data. |
| Data modelling and semantic models | I design models, from SAP IDT universes to Power BI semantic models, with no duplicates, relational integrity and parameters, so they are easy to explain and cheap to change. |
| SAP HANA, SAP IQ, SQL Server and Oracle | I work with them as sources and targets of data, to connect reports with the systems where the real data lives. |
| Client and stakeholder relationships | I gather requirements, validate deliverables and talk directly to the business, to turn what they need into an analytical solution that answers a real decision. |
| Team leadership and training | I led a team of 3 on a project (planning and delivery) and taught SAP BusinessObjects and SAP Analytics Cloud courses, so client teams can work independently. |
| Row-level security (RLS) | I restrict which data each person sees within a single report, so it can be shared with several users without exposing information that is not theirs. |
| Agile / Scrum, Jira and Confluence | I work in Scrum teams, with the work in Jira and the documentation in Confluence, to deliver iteratively and with traceability. |
| Azure Databricks and Unity Catalog | I build and maintain notebooks on Silver and Gold tables governed with Unity Catalog, to prepare in an orderly way the data that Power BI consumes. |
| Applied AI | I use it for specific tasks and as support for documentation, always reviewing the result, to save time without losing rigour. |
