Walery – Portfolio

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.

In my work I combine three perspectives: analytical — I turn numbers into insights and decisions; engineering — I break problems down and look for the simplest solutions; humanistic — I make sure the result is readable and useful.

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.
