Sencha's official partner in Europe

Sencha services

JNESIS has since 2013 a close partnership with Sencha.

This partnership implies constant interactions with the community, an active participation in events at the European level (Sencha Roadshow Paris and Zürich), and two participations as a speaker in the global Sencha convention (San Francisco, 2015 and Las Vegas, 2016).

We also act as a local proxy for French and Swiss clients in need of other services on top of Sencha’s offer, notably for development (on and off-site), training in French, consulting and expertise.
