About Nicolay

As an experienced Data Engineer and technical team leader, I possess the skills and knowledge to set up and maintain robust data stacks using a variety of tools and platforms. My expertise includes mastering Databricks, Snowflake, DBT, and AWS, which enables me to design and implement highly efficient data pipelines. In addition, I am familiar with the Microsoft Stack, including SQL Server, SSIS, SSAS, SSRS, and Power BI.

Building high-performance Data Warehouses is one of my core competencies, and I am proficient in various schemas such as the star schema or Data Vault 2.0. If you need performance optimization for your database, I can apply techniques such as query optimization and the elimination of bottlenecks in your data stack. I offer performance optimization services for platforms such as Redshift Database, SQL Server, and Snowflake. I also have experience setting up Data Lakes for use cases such as data ingestion into Snowflake, Databricks, or Athena.

Practically, I can support your company by implementing a data stack with these tools that enables data processing, data modeling, and data visualization. I am able to provide ongoing maintenance and optimization to ensure optimal performance of the data stack. My industry expertise includes e-commerce, mobility, marketing, and the energy sector, and I can deliver valuable insights and analyses by creating comprehensive reports with Power BI, Google Looker, SSRS, and Tableau.

In addition, I am proficient in agile methods and possess the flexibility to adapt to changing project requirements and schedules. Please do not hesitate to contact me for further information on how I can support your data engineering projects.
