How I can help your business:
Optimize your query to save money. For instance, a 1 TB query may cost $6.50 in GCP, but after optimization, it can be as low as $0.06. Imagine running hundreds of such queries. I provide service in query optimization and logical/physical model support in order to avoid poorly written queries.
What is more important is having all your data sources connected to your data platform. I have broad experience with ETL processes, such as setting up CDC for replication and configuring further processes to deliver data into target tables. In addition, writing queries to manipulate and load huge amounts of data into tables is one of my main strengths.
Automation of manual Excel reports is a vital step in a company's success. Having your data visualized allows managers to track changes and react quickly to situations. BI reports and dashboards can be updated on demand or on any scheduled frequency. Modern software like Tableau and Fine BI allows to visualize any kind of data, making it understandable for colleagues with any level of experience. Along with visualization, I offer analytical reports based on statistical tests to gain more insights from your data.
