ENGINEER
Engineering is more than code and schematics — it's a way of thinking about data and technology as tools to create value.
HUMANIST
Art, design and storytelling are three languages I use to convey ideas — in projects, space, and form itself.
Who I am
Hi! I’m Walery — an engineer, programmer and analyst. I have over a decade of experience in the electrical and telecom industries and several years’ practice in Python, data analysis and modeling.
On a daily basis I work on analytics, technical documentation and audits, but what I enjoy most is designing and building tools that genuinely improve workflows — from automation and data pipelines to reporting and machine-learning models.
I most often work with Python (pandas, scikit-learn), SQL and Power BI. I also use Django and FastAPI in projects, and tie everything together with Git — mainly for building apps, automation and analytical tools.
After hours I draw, paint and develop my own web projects — realizing my own ideas and testing new solutions.
If you need someone who can translate an idea into a working tool — get in touch.
What I Can Help With
Analytics & Development
I design and implement data pipelines, ML models and web applications. I combine engineering experience with analytics to build tools that support processes and decisions.
Standards & Training
I create technical documentation, guidelines and engineering standards. I conduct audits and certification training, ensuring clarity and practical implementation.
Visualization & Reporting
I design reports and dashboards in Power BI and Excel — tailored to the audience and ready to use. I make sure the data speaks for itself.
Projects
ML Training Intensity Prediction
A complete ML pipeline (scikit-learn + FastAPI) developed from my thesis: data from Garmin, Random Forest with R²≈0.93, and REST API. You input your heart rate, distance, and activity data, and you get estimated calories per minute (the model was trained on our own data, so it's not universal).
Pandas Tabular Convert
A CLI tool for converting CSV, Excel, JSON, Pickle, and Parquet to a unified DataFrame (Pandas). It allows for structure preview, column cleanup, and export.
Python - Text Similarity Analysis
Compares a master document with other files using TF-IDF and cosine similarity. Useful for analyzing large datasets and detecting similarities.
Data Analysis & ML Projects
A collection of projects in Power BI, Excel, Python, and R for visualization, statistical analysis, and predictive modeling.
Windows Registry Tweaks
A collection of minimalist .reg tweaks for Windows 10—context menus, telemetry, UI animations. Each folder contains a pre-made tweak and a file to restore the original.
Pygame Alien Shooter
Retro-arcade gameplay in Python and Pygame. Waves of space invaders, dodging and shooting—with hero selection and increasing difficulty with each round.
Tkinter Utility Tools
Tkinter desktop application with a set of small system tools: a secure key generator, a duplicate finder, and a detector of paths exceeding the 260-character limit.
Tkinter Tesseract OCR
Lightweight GUI app (Tkinter + Tesseract) for OCR: load an image, crop the area with the mouse and extract text ready to copy.
Tkinter Document Viewer
Lightweight PDF, EPUB, and MOBI viewer in Python (Tkinter). Zooming, text search, page navigation, and full-screen mode.
Flask PDF Tools
Web application for working with PDFs: combining and splitting - with CAPTCHA protection and built-in security mechanisms.
OpenCV Sketch Effects
GUI app (tkinter + OpenCV) that transforms images into sketches, contours, and tattoo-ready tracing templates. Generate pencil, binary, and grayscale effects with live preview and export.
Folium City Visits
Visualization in Python/Folium (.html map). The CLI application generates an interactive map of Poland with colored city markers based on data stored in SQLite.
Tkinter File Organizer
GUI file organizer (Tkinter). Scans folders, sorting images, documents, videos, audio, and archives into dated directories—with SHA-256 deduplication and preview mode.
