I am a Systems Engineer with more than 10 years of overall experience in different Business Intelligence-related roles. I have been involved on projects related to all technical aspects of a BI solution (from setting up a cloud server up to some basic visualization reports) and hope to apply this experience to solve concrete business questions or automation requests.
Key skills and experiences:
- Highly proficient in SQL, having worked part of my experience as Teradata DBA and the rest as a frequent user (from analysis to table design and performance optimization)
- Experience with various ETL tools (Pentaho, Informatica PowerCenter, Ab Initio) and also with Python scripts used for integration purposes
- Ability to design a BI solution end-to-end starting from the required KPIs and datapoints, and implement via an AWS setup (EC2, Amazon S3, Amazon Redshift, Amazon QuickSight) with one real-life success story
- Acute business sense resulting from years of speaking with business stakeholders from various trades (financing, banking, online commerce)
- Hands-on experience with Salesforce CRM (as an admin and some basic development/Apex) as a result of the integration with our BI setup in a previous role
