I'm offering
Hi from London! I'm a Data Engineer with good Datawarehousing and BI experience. I love to solve challenges in business analytics from data integration to near-real-time solutions. Having worked with cloud and on-prem solutions, I can offer reliable and predictable outcomes within a certain timeframe. I also like to be in part of migration projects where I can show the return of the migration decision, especially from traditional solutions to the cloud. Looking forward to working with you.
