About

With extensive experience as a Data Engineer and Systems Analyst, I have honed my skills in SQL, PL/SQL, and various data engineering technologies. Currently, I am working at Eviden, where I develop processes to onboard data sources to the Google Cloud Platform, analyze client requirements, and solve complex big data issues. I design, write, and maintain Apache Airflow jobs, develop ETL/ELT solutions, and automate data flows. My technical expertise includes Python, Linux bash scripting, and JSON, allowing me to work effectively with data flows, server connectivity, and multiple technologies. Previously, I worked at Atos as a Data Engineer, focusing on ETL layer design and implementation for new data warehouses. My role as a BI Developer involved working with Oracle and Unix technologies. At PKO Bank Polski, I supported documentation creation, testing, and monitoring of banking transaction systems. My experience at CGI Information Systems included database administration, system monitoring, and SQL programming. I also worked at Orange as a Systems Analyst and SQL Analyst, where I optimized SQL reports, participated in IT projects, and ensured information security. My education at the Warsaw University of Technology provided a strong foundation for my career in data engineering and analytics.

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. “
