PyCon Lithuania 2026

Keynote

Mark Smith

Head of Python Ecosystem, JetBrains

Mark has been writing Python code since the year 2000. But the interesting things about him are that he makes an excellent Old Fashioned cocktail, he likes to design quasi-useful things for 3D-printing, he has a terrible mechanical keyboard habit, and he talks too much in the pub. He lives in Edinburgh, Scotland with his family and too many dogs.
