Work Experience
Data Warehouse and BI Developer
2017 - PRESENT
Intuitive Thinking
- Developed a highly configurable data warehouse framework, refined over the past five years after an initial 6-month project. It combines the configurable star schema's performance and usability and is complimented by the data store flexibility.
- Created a Microsoft Power BI report pack for accounting consultancy clients and included the integration of write-back visuals, facilitating cell-level commenting and budgeting while redesigning the existing star schema data model.
- Built a tool for social media monitoring and reporting using Twitter API and Google Translate API. The tool retrieves social media posts that suggest potential clients' financial wrongdoing for due diligence purposes.
- Utilized Temenos Transact banking data to develop complex logic and provide funds transfer pricing for assets under management (AUM), flow, and margin and base rate analysis.
- Researched various data tools and resources to find new ways of adding value to businesses while attending conferences, exploring new technologies, and keeping up to date with market changes.
- Worked for Fine Win Client using complex SAP Hana data. Reduced Azure DB costs by around 4,000 per month. Stabilized a dysfunctional ETL to reduce the reported issues by around 7 to 1. Led and supported the team on many high-priority projects.
- Reduced cloud database costs for the client by around 30% and decreased tickets raised from five to one, with a piece of work to stabilize and simplify the existing data warehouse BI setup on Azure and Power BI.

Experience
Data Warehouse Framework
Developed a highly-configurable data warehouse framework that has been in production at a private bank in Luxembourg since 2017. The framework was built within the SQL Server and combines the performance and usability of a star schema, complimented by the flexibility of a data store.
The solution uses a dynamic ETL accommodating dimension and bridge, in addition to transactional, snapshot, and accumulating tables. It includes comprehensive logging, covering schema changes, batch details, and ETL steps for maintainability.
As part of the project, I delivered cubes using SSAS, reports using SSRS, used SSIS file exports for third-party systems, and allowed users to maintain their hierarchies and other configuration using Master Data Services.

Client Report Pack Development
Created a new data model and process for implementing predefined Microsoft Power BI reports and data sets that accounting consultancy users can deploy without having a technical background.
Microsoft Power BI write-back tools integrated into the report pack allow budgeting and commenting within Microsoft Power BI. I designed the look-and-feel of the reports and documented the process for future implementations.
