Hi, Gray Cells was established in 1996 as a holding company. With associates we were focussing on Oracle as database, application and reporting. As the Oracle products on reporting then were not satisfactory, we used Business Objects for reporting, which later on would be acquired by SAP. Since 2011 we have added cloud to our focus and because of the acceptance of the use open source software by major companies, we took that on as well. Because of the maturity, the many products you get and the continuous research and development on existing and new products, we chose for Amazon Web Services as the platform in the cloud. Nowadays we are able to help you from building applications, interfacing from and to other applications to managing the data warehouse along with business intelligence and data analysing in the cloud. Terms we are familiar with : Tibco Jaspersoft, QlikView, Tableau, SAP BI, MapInfo, Talend, ElasticSearch, Logstash, Kibana, Java, Git, Apache, Tomcat, Spark, Cassandra, Kafka, Python, Oracle, Amazon Web Services, Redshift, IAM, VPC, OSx, Unix, Linux, Windows, data vault, star, snowflake and probably many more.
