Currently, I am working as a Data Scientist in the Financial Crime Threat Mitigation department at Mthree for HSBC in Poland since July 2020. My primary responsibilities include working on a fraud detection classification project and leading the transition from old to new data source systems, which involved modifying all existing pipeline and modeling scripts. I am skilled in applying new logic for running dbt pipelines in Python and SQL to generate high-quality data and create champion models in BigQuery. Additionally, I write testing scripts in Python to compare output versions, handle confidential data with risk control measures, and work within an agile methodology. The technologies I use include Python (with libraries such as pandas, sklearn, numpy, matplotlib, sns), JupyterLab, SQL, GCP (Google Cloud Platform), BigQuery, Github, and JIRA. Previously, I worked as a Data Scientist in the Advanced Analytics team at Cisco Poland from July 2019 to July 2020. During this time, I developed regression and classification models using supervised machine learning algorithms and analyzed both structured and unstructured data from various sources such as SQL, Snowflake, and Hana. I also gathered project requirements through stakeholder meetings. Before Cisco, I was a Data Analyst in the Evidence Lab department at UBS Business Solutions Poland from January 2017 to June 2019, where I transformed and analyzed large datasets into client-friendly Excel models, automated data management processes using Python, and conducted industry research using market research methodologies. My educational background includes a Bachelor's degree in Information Technology and Econometrics from AGH University of Science and Technology in Cracow, Poland, which I completed in September 2017.Tech Stack

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. “
