Experience
Design and Implementation of ETL Servers
As the system support manager, I worked with my team to prepare ETL environments for our customers. We pulled data files from S3 buckets, a local hard disk, and a central database, unpacked them, and extracted useful and meaningful data using custom data readers and format files. The descriptive data from data sources were loaded into Oracle and the RAW data into the Cassandra database.
Cars Health and Performance Monitoring
Using the OBD2 connector, I collected real-time data from many car sensors and sent them to a server. A script on the server pulled those logs and fed them to a dashboard that read the data and visualized it to make it easier for the owner to compare the current readings with previous ones. For someone equipped with the needed knowledge, this dashboard can predict problems before they happen.
