Hi I am Upul Rajasekera and specialized in Data Engineering, Business Intelligence technologies (SSIS, SSRS) and SQL Server (Complex Queries / Procedures, Query Optimization). My overall Data Engineering and Business Intelligence experience is 9+ Years and also I have worked with many leading companies in Sri Lanka.
