Translating a draconic bloodrager from Pathfinder to 5E

I am planning a summer campaign. I have a player with whom I have played some 5e recently, but who currently plays Pathfinder and has played Shadowrun in the past.

One of the characters he has played in Pathfinder is a draconic bloodrager. He likes the character concept and wants to implement something similar in 5e and is looking for some guidance.

I am not a Pathfinder player, but I have looked at the Pathfinder SRD and I am not seeing that there is a 5E equivalent to the PF draconic bloodrager.

The draconic bloodrager seems something like a 5th Edition multi-classed berserker/eldritch knight/draconic sorceror, only a barbarian can’t cast spells while raging, which seems contrary to the PF bloodrager.

Can anyone provide me with some guidance to pass on to this player?
