03 / A little more

Curious by default.
Careful by practice.

I like working at the intersection of a clear user experience and a dependable system underneath it. My path has moved between paywall development, e-commerce, JavaScript, Python, data workflows and deployment, always with the same question: how can this process become clearer, faster or more useful?
