What I'm looking for

I'm looking to advance my agile career with a growing or high-performing company, contributing my technical background and supporting people and cross-functional teams in a challenging environment.

At MIMECAST, I work on migrating facts and dimensions from SQL Server to Snowflake using DBT, and on moving on-premises SQL to AWS. I also create SSIS packages and support data validation and testing.

I assist the Scrum Master by facilitating stand-ups, sprint refinement, planning, and retrospectives, and support Product Owner backlog maintenance. Previously, I developed BI solutions at Hollywoodbets and worked on SQL, SSRS, and ETL projects at Coronation Fund Managers, Kurtosys, and Omni Africa.
