Walery – Portfolio

ENGINEERING

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 with over a decade of experience in production, electrical and telecom industries, and several years of practice in Python, data analysis, and automation. On a daily basis, I work on documentation, design, reporting, audits, machine learning, and custom-built tools — from automation to data-driven solutions.

I combine three perspectives: analytical — turning numbers into value, engineering — with a structured approach to problems, and humanistic — emphasizing clarity and practical usability.

After hours I draw, paint and develop my own web projects — like an online gallery or a tongue-twister platform. Below are the areas I operate in and where I am happy to help — all tied together by one thing: I enjoy building things that work. If you’re looking for someone who combines engineering with creativity — get in touch! I’d be glad to take on a new challenge.

PS. Even if your idea doesn’t fit the listed areas, write to me — we’ll figure something out.

What I Can Help With

Telecommunication & Electrical

Years of experience in the telecom, electrical and industrial (R&D) sectors — from design and analysis, through cost optimization and risk management, to audits and quality control. From environments where quality is paramount, I’ve developed an approach grounded in analysis, effectiveness, and attention to detail.

Data Analysis, Automation & ML

I design and implement data-driven solutions — from pipelines and process automation in Python to predictive models and Jupyter analyses. I combine engineering insight with data science to create tools that deliver real business value.

Technical Documentation, Guidelines & Training

I create and manage technical documentation: designs, guidelines, engineering rules, and standards. I ensure clarity, compliance, and practical usability, including when conducting training courses that support the implementation of standards..

Custom Solutions

I build applications, automations and tools — from MVPs to full-scale systems. I integrate data, develop predictive models and optimize workflows, delivering reliable code and working solutions without unnecessary extras.

Visualization & Reporting

I design reports and dashboards in Power BI, Looker, and Excel that connect data with a narrative, show key metrics, support decisions, and help manage performance—no fancy charts, just insights that matter.

Creativity & Design

I draw, paint and design — from murals and illustrations to custom artwork on training equipment and interior elements. I also work with technical and CAD design, combining engineering precision with a creative approach to form and detail.
