About me

I write Python scripts to clean data, automate repetitive tasks and prepare import files. I combine Excel spreadsheets, API responses and website data into structured datasets, charts and product catalogues.

For a commercial e-commerce project, I built a workflow combining ERP spreadsheets, product-page data and descriptions generated through the OpenAI API. The output was a validated XML file containing 260 products for import into IdoSell, with duplicate checks and review spreadsheets for ambiguous records.

I can help with: • cleaning, merging and converting Excel, CSV, JSON and XML data; • API integrations and web scraping; • product-data preparation and e-commerce imports; • OpenAI API workflows with structured-output validation; • scientific and measurement-data analysis, numerical calculations and visualisation; • generating PDF documents from structured data using Python and LaTeX.

I hold an MSc in Physics from the University of Warsaw and engineering degrees in Technical Physics and Aut

Jul 2025 - Aug 2025

Research Intern — Data Analysis

Center for Theoretical Physics PAN

Analysed cosmological simulation data, generated structure maps and catalogues, and statistically compared results across methods. Implemented a V-web classifier in Python.

Apr 2023 - Sep 2023

Research Intern — LHCb Data Analysis

Institute of Nuclear Physics PAN

Analysed LHCb experiment data using ROOT, C++ and Python. Applied event selections to reduce background and fitted statistical models using B2DXFitter.

Oct 2019 - Oct 2022

Mechanical Designer — Student Rover

Silesian University of Technology

Designed and built mechanical subsystems for a student rover, including suspension-design work. Used Autodesk Inventor, Fusion 360 and SolidWorks for CAD modelling and ANSYS for structural analysis.

Portfolio

Cosmic structure analysis in Python

For a CFT PAN project, implemented a V-web classifier and data reader in Python and adapted existing T-web code. Compared simulated structure catalogues across methods and resolutions, then published code and notebooks.

3D CAD modelling of rover components

Designed and built mechanical subsystems for the Silesian Phoenix student rover, including suspension-design work. Used Autodesk Inventor, Fusion 360 and SolidWorks for CAD modelling, and ANSYS for structural analysis.

HEP-Dooble: YAML-to-PDF generation

Developed Python scripts that turn YAML content into particle-physics educational cards. The workflow generates LaTeX and compiles PDFs with pdflatex, automating the preparation of print materials.

Python: 260-product import for IdoSell

Built a Python/pandas workflow combining ERP spreadsheets, website data and OpenAI API descriptions. Produced validated XML for 260 IdoSell products, with duplicate checks and spreadsheets for reviewing ambiguous records.
