About

I am a highly experienced Big Data Architect with a strong background in the design and implementation of data warehouses and business intelligence tools. Over the years, I've honed my skills in Scala programming, Apache Spark, and Azure Databricks, specializing in machine learning and big data systems. My professional journey has seen me lead teams and deliver complex projects, such as designing machine learning models to predict system failures and implementing robust data warehouse solutions for various organizations. I graduated with honors in Computer Science from Warsaw University, where my thesis focused on genetic algorithms, heuristic searching, and machine learning. Currently, I am a Big Data Architect at Lingaro Data Science and AI Competence Center, where I design and develop ETL engines using Python and Azure Databricks. Prior to this, I led the BI team at Asseco, where I was responsible for several high-profile projects, including data warehouses and reporting systems for government agencies. My technical expertise is complemented by certifications in Scala, Azure, and Oracle, and I am passionate about continuing to push the boundaries of big data processing and machine learning.

Best back-end engineers I've ever worked with...​

“I interviewed about a dozen different firms. DevsData LLC is truly exceptional – their backend developers are some of the best I’ve ever worked with. I’ve worked with a lot of very well-qualified developers, locally in San Francisco, and remotely, so that is not a compliment I offer lightly. I appreciate their depth of knowledge and their ability to get things done quickly. “
