About

As a Business Intelligence developer and data analyst with over 12 years of experience, I have honed my skills in supporting senior management decisions within the financial and IT sectors. My expertise includes writing advanced T-SQL queries, creating complex stored procedures for financial data analytics, and developing ETL processes using SSIS and Talend. Additionally, I excel in creating ad-hoc and subscription-based reports using SSRS and Power BI, managing and developing databases on MS SQL Server, and developing data warehouses and data vault models. With a strong foundation in mathematics and statistics, I have built and implemented credit scoring models and designed business systems, such as electronic credit applications. Throughout my career, I have held various roles, including Senior Data Warehouse Engineer at RCI Banque, Business Intelligence Developer at Liberty Mutual Insurance, and Fullstack SQL Developer at PwC IT Services. I have successfully developed data warehouses, managed databases, and created ETL processes across different platforms, including AWS and Azure DevOps. My greatest accomplishments include restoring SQL Server functionality, migrating data sources, and creating key performance indicator reports from scratch. With advanced certifications in SQL Server, Power BI, and AWS, I am well-equipped to tackle complex data challenges and provide valuable insights to drive business decisions.

Best back-end engineers I've ever worked with...​

“I interviewed about a dozen different firms. DevsData LLC is truly exceptional – their backend developers are some of the best I’ve ever worked with. I’ve worked with a lot of very well-qualified developers, locally in San Francisco, and remotely, so that is not a compliment I offer lightly. I appreciate their depth of knowledge and their ability to get things done quickly. “
