Iago Nus Martinez

I am a Data Engineer specialized in transforming data into practical, business-ready solutions. I work with Python, SQL, database modeling, efficient ETL development, and query optimization. I also build dashboards in Power BI, Metabase, or Grafana, and use Docker to create reproducible environments, along with Git for clean and reliable version control.

My working style is agile, organized, and results-oriented: I listen to what you need, design scalable solutions, and deliver value from the very first sprint. I take on all types of projects — from extracting information from a simple Excel file and creating a clear visualization, to more complex data engineering solutions.

I add value through:

• Python development for automation, cleaning, analysis, and small internal applications.

• Robust and scalable database modeling aligned with business needs.

• Clean and efficient ETL pipelines focused on stability and maintainability.

• Optimization of database performance and SQL queries.

• Use of Docker to create reproducible testing environments and make execution easy for any client.

• Working with Git to ensure traceability, structure, and smooth collaboration.

• Building functional and clear dashboards in Power BI, Metabase, and Grafana to support decision-making.

My goal is to provide you with reliable data processes, useful visualizations, and tools that are easy to understand and maintain.
