This year with hopes of attending some events in person, I've pushed a few talks to the Devoxx UK 2022 conference being held from 11-13 of May in London.
This is a rather close location for travel for me so seemed like a good one to put on my Spring list of conferences to target.
The Devoxx series is well know and I've attended and spoken at multiple sessions for the Belgian version in the past. It's very developer centric with a lot of good depth and knowledgable attendees.
My submissions are diverse and across the board as far as technical depth, architectural coverage, and type of sessions.
