02 / About

I like the part where an idea becomes a working tool.

I’m building my experience in Python and data science through hands-on projects: APIs, small services, data cleaning and machine-learning experiments.

I care about legible code, a sensible scope, and shipping something that is straightforward to use and maintain.
