Martin L.

I’m a self-motivated data professional, passionate about what I do. I take initiative, meet deadlines, and always focus on solving my clients’ problems. Thanks to that, I’ve built a strong reputation in my company, and now I’m working to do the same in the freelance community.

I’m comfortable working with both technical teams and business roles. I make sure to understand the needs behind each project, communicate clearly, and deliver effective and scalable solutions with business value.

My experience covers the full data pipeline: I’ve worked on both ETL and ELT processes, data modeling (Star Schema and Data Vault), and data visualization. I’ve designed pipelines on-prem and in the cloud, with a current focus on Snowflake. I’ve also worked on metadata and data catalogs, helping to structure back-end systems of a custom Data Lake platform.

Some of my key contributions include:

- Designing and optimizing data pipelines

- Creating reusable templates for dimension tables

- Replicating data models across environments

- Working with metadata for better data governance

I’m reliable, curious, and always open to learning. I’m actively looking for projects where I can contribute with what I know, while continuing to grow and provide data-driven value.

Don’t hesitate to reach out if you think I can help with your data challenges!
