I’m Lucian Lazar, a data consultant and trainer with 20 years of experience across industry and academia. I currently build data solutions at Remote and author data and AI courses for Pluralsight.
Data consulting and training in SQL, data engineering, and AI
I help teams design databases, improve SQL performance, and build reliable data pipelines across Oracle, SQL Server, PostgreSQL, MongoDB, and cloud platforms such as Snowflake and Databricks.
I offer practical training in SQL, database development, data engineering, and AI for developers, analysts, and business teams. Topics range from advanced SQL and query tuning to prompt engineering, AI in databases, and AI agents. My approach draws on industry experience, university teaching, and online course creation.

Data solutions
Since 2010, I’ve worked on an enterprise sales performance management platform that calculates commissions and incentives for Fortune 500 and FTSE 100 companies and processes tens of millions of rows of data a day. As its go-to database engineer, I’ve:
- Helped build an MCP server prototype that lets AI agents query client data in natural language through controlled, read-only access.
- Delivered direct database access that lets clients query their data from their own BI tools with read-only permissions.
- Built and maintained the Oracle code behind the platform’s data processing, including data migrations and troubleshooting failed loads.
- Delivered recurring data reports for clients, leadership, professional services, and product teams, and supported the company’s AI initiatives.
