About

With over 15 years of deep, hands-on experience, I specialize in building modern data platforms that drive innovation, scalability, and measurable business value. From designing Lakehouses and Data Warehouses to leading large-scale cloud migrations and integrating Gen AI capabilities, I bridge cutting-edge technology with real-world impact. My journey spans all three major clouds—Azure, GCP, and AWS—and tools like Databricks, Synapse, Snowflake, BigQuery, and Fabric. I've helped financial institutions, insurers, and global enterprises modernize their data ecosystems using Lakehouse, PySpark, CI/CD, and IaC principles. I was also a speaker at conferences such as Data Science Summit, SQL Day, CDO Forum, Data & AI Warsaw, Tech Summit and Microsoft Tech Summit, where I share insights on topics like Databricks, Gen AI, Microsoft Fabric, GCP, and cloud-native data architectures. 🔧 Core Competencies: - Cloud Data Architecture (Azure, GCP, AWS) - Modern Data Warehousing & Lakehouse (Databricks, Fabric, Synapse, BigQuery, Snowflake) - Gen AI Integration in BI & Data Platforms - Scalable ETL/ELT Pipelines (PySpark, Data Factory, Dataflow, Glue) - CI/CD & IaC (Azure DevOps, Terraform, Cloud Build) - Landing Zone design - Multicloud Migrations & Optimization - Public Speaking & Thought Leadership - Team leading If you're building a future-ready data platform or seeking to modernize legacy systems with AI and cloud-native tools—let’s connect. 🔗 Blog: https://medium.com/@mariusz_kujawski
