optimized database systems provide solution data analytics experience conversion build database programs objects snowflake oracle teradata worked projects wide range data projects including data warehouse software services data migration ability build processes using snowsql command line interface javascript stored procedures near real time bulk batch loads knowledge creating snowflake user defined functions materialized views merge statements query optimization using profiler created snowpipe continuous data load aws s3 buckets azure blob storage good knowledge snowflake virtual warehouse internal external stages materialized view zero copy cloning query profiling user defined functions transient tables advanced dml like merge common table expressions good knowledge various dimensional models like star schema hybrid models strong experience extraction transformation loading etl data various sources data warehouses data marts using informatica power center repository manager designer workflow manager workflow monitor metadata manger created complex mappings using mapplets new transformations like sql transaction control worked data migration processes files database across relational databases good experience working various type facts slowly changing dimension scd tables handson experience across stages software development life cycle sdlc including
