extensively involved etl development using iics informatica power center 9x10x experience working informatica iics tool effectively using data integration premises cloudbased data migration multiple source systems experience iics data integration administrator monitor services experience building service connectors real time integration third party applications like google cloud storage bigquery strong technical experience building data integration processes constructing mappings tasks task flows schedules parameters used informatica designer components source analyzer transformation developer mapplet mapping designer worked extensively complex mappings using multiple transformations like source qualifiers expressions filters joiners routers union unconnected connected lookups aggregators hierarchy builder hierarchy parser stored procedures rank normalizer sequence sql experienced performance tuning jobs strong finding bottlenecks fixing using various tuning methods like session partitioning reducing lookup sizes using persistent caches pushdown optimization etc experience implementation cdc scd1scd2 high experience rdmbs oracle including complex sql constructs ddl
