Hi, I’m Walery — I build data products, automation tools and backend applications.
Currently open to Python, Data and Automation opportunities.
I primarily work on:
- data and ML pipelines
- desktop applications
- full-stack Django projects
- API services
I enjoy solving messy problems and turning them into usable products.
Outside tech: combat sports, art and books.
