About

With over a decade of experience as a Principal Data Engineer, System Architect, and Hadoop ecosystem specialist, I have successfully led and contributed to numerous international projects across various industries, including Telco, Finance, Entertainment, Manufacturing, Pharma, and Advertisement. My expertise spans design and delivery of analytical-oriented solutions, OpenSource-based data processing, and project management methodologies such as Agile Scrum and Waterfall. Proficient in multiple programming languages and databases, I excel in architecting and implementing complex analytical platforms using cutting-edge technologies like Apache Hadoop, Apache Spark, and cloud services from Azure and AWS. In my recent projects, I've demonstrated my skills as an Architect and Data Engineer for Telcos in Germany and Poland, where I designed scalable platforms for network quality monitoring and managed data ingestion processes for multiple data sources. Additionally, I served as Lead Architect for a global truck manufacturer, designing analytical platforms for IoT sensor data analysis, with a focus on security and GDPR compliance. My extensive experience also includes roles as a Solution Architect for a global Pharma company, where I optimized historical studies data usage through a new analytical platform, and as a Team Leader and Architect for GG Network, where I spearheaded the creation of one of Poland's first big Hadoop clusters, showcasing my expertise in parallel computing and big data analytics.
