Sorcerer/Fighter Build

I made a sorcerer/fighter build and would like some feedback to make it better.

Interesting choice of Multiclass, any particular reason?

The biggest obstacle you’re going to have is that by splitting your focus between charisma for the spell casting and strength for the fighting you’ve got really low Dex and Con. You're going to be very squishy trying to fight on the front lines, with a really low AC and a really low HP. Most of your spells would also be cast at disadvantage if you were trying to be up close to enemies and melee fight. You could consider switching the strength for Dex, which would solve the AC at least, and then use either ranged or finesse weapons both of which use Dex. However at that point if you’re going ranged why not just use spells?  

Spellwise you missed Shield and Misty Step, two of the best low level spells in general. 

Not sure you want a Javelin considering you have Jump to move far and Magic Missile to hit things distant.  A Bow might be better for when you have to use many ranged attacks.

You also split your levels down the middle.  A lot of the time, specializing in one is more powerful.  If you went Fighter 3/Sorcerer 7, instead, you would get 4th level spells, resistance to your draconic elemental, more damage with it, and more inate sorcery (at the cost of one bonus attack, tactical shift and an ability score improvement..  If you went Fighter 7/Sorcer 3, you get fighting style, at the cost of a 3rd level spell and sorcerors restoration.  

Welp, I can only see the 1st level version now but I would take the least amount of Fighter levels you can.  I wouldn't worry about Extra Attack or Strength, I'd go with True Strike (2024 rules) for melee damage.  2 Fighter levels and Sorcerer the rest of the way will get you most of the good stuff.

Fighter 4 to get the subclass and ASI is fine, I'd still rather have 4th or even 5th level spells though.  IF your plan is heavy armor then the +2 DEX bonus isn't that useful, those points could go elsewhere.  Are you using 2024 rules?

The link should be fixed

First of all, you are missing Cantrips. You get 5 Cantrip spells for your Sorcerer level. Booming Blade and Green-Flame Blade both work with your melee weapons. I also recommend adding some ranged Cantrips like Sorcerous Burst.

Secondly, you should probably tailor some of your spells to support your character during combat. Shield is an absolute must for any melee spellslinger. Misty Step can get you out of sticky situations if you need escape options. Blur also goes a long ways to make it difficult to hit you.

Something to consider: War Caster is great feat to have. It will let you cast spells when your wielding a shield and a weapon or when wielding two weapons. Most importantly, it will give you Advantage on Concentration checks (casting a spell on a Opportunity Attack is pure gravy).
